It is dense and white arteria hyaloidea purchase cheapest lozol and lozol, and continuous with the cornea anteriorly and the dural sheath of the optic nerve posteriorly blood pressure chart according to age and weight best 1.5mg lozol. Across the posterior scleral foramen are bands of collagen and elastic tissue hypertension kidney disease buy lozol with a visa, forming the lamina cribrosa blood pressure what do the numbers mean generic lozol 1.5mg otc, between which pass the axon bundles of the optic nerve. The outer surface of the anterior sclera is covered by a thin layer of fine elastic tissue, the episclera, which contains numerous blood vessels that nourish the sclera. The brown pigment layer on the inner surface of the sclera is the lamina fusca, which forms the outer layer of the suprachoroidal space. Slightly posterior to the equator, the four vortex veins draining the choroid exit through the sclera, usually one in each quadrant. About 4 mm posterior to the limbus, slightly anterior to the insertion of the respective rectus muscle, the four anterior ciliary arteries and veins penetrate the sclera. The histologic structure of the sclera is remarkably similar to that of the corneal stroma (see the next section), but it is opaque rather than transparent mainly because of irregularity of the collagen lamellae and higher water content. It is inserted into the sclera at the limbus, the 27 circumferential depression at this junction being known as the scleral sulcus. The average adult cornea is 550 fim thick in the center, although there are racial variations, and about 11. They run parallel to the surface of the cornea and, by virtue of their regularity, are optically clear. The lamellae lie within a ground substance of hydrated proteoglycans in association with the keratocytes that produce the collagen and ground substance. The endothelium has only one layer of cells, but this is responsible for maintaining the essential deturgescence of the corneal stroma. The endothelium is quite susceptible to injury as well as undergoing loss of cells with age: the 2 2 normal density reducing from 23,000 cells/mm at birth to 2000 cells/mm in old age. Endothelial repair is limited to enlargement and sliding of existing cells, with little capacity for cell division. Sources of nutrition for the cornea are the vessels of the limbus, the aqueous, and the tears. The sensory nerves of the cornea are supplied by the first (ophthalmic) division of the fifth (trigeminal) cranial nerve. The transparency of the cornea is due to its uniform structure, avascularity, and deturgescence. It is the middle vascular layer of the eye and is protected by the cornea and sclera. Iris the iris is a shallow cone pointing anteriorly with a centrally situated round aperture, the pupil. It is positioned in front of the lens, dividing the anterior chamber from the posterior chamber, each of which contains aqueous humor that passes through the pupil. The sphincter and dilator muscles develop from the anterior epithelium, which covers the posterior surface of the stroma and represents an anterior extension of the retinal pigment epithelium. The heavily pigmented posterior epithelium represents an anterior extension of the neuroretina. Iris capillaries have a nonfenestrated endothelium, and hence do not normally leak intravenously injected fluorescein. Pupillary size is principally determined by a balance between constriction due to parasympathetic activity transmitted via the third cranial nerve and dilation due to sympathetic activity (see Chapter 14). The Ciliary Body the ciliary body, roughly triangular in cross section, extends forward from the anterior end of the choroid to the root of the iris (about 6 mm). It consists of a corrugated anterior zone, the pars plicata (2 mm), and a flattened posterior zone, the pars plana (4 mm). They are composed mainly of capillaries and veins that drain through the vortex veins. The capillaries are large and fenestrated, and hence leak intravenously injected fluorescein. There are two layers of ciliary epithelium: an internal nonpigmented layer, representing the anterior extension of the neuroretina, and an external pigmented layer, representing an extension of the retinal pigment epithelium. The ciliary processes and their covering ciliary epithelium are responsible for the formation of aqueous. This alters the tension on the capsule of the lens, giving the lens a variable focus for both near and distant objects in the visual field. The longitudinal fibers of the ciliary muscle insert into the trabecular meshwork to influence its pore size. The arterial blood supply to the ciliary body is derived from the major circle of the iris. The Choroid the choroid is the posterior segment of the uveal tract, between the retina and the sclera. It is composed of three layers of choroidal blood vessels: large, medium, and small. Blood from the choroidal vessels drains via the four vortex veins, one in each of the four posterior quadrants. It is suspended behind the iris by the zonule, which connects it with the ciliary body. The lens capsule is a semipermeable membrane (slightly more permeable than a capillary wall) that will admit water and electrolytes. With age, subepithelial lamellar fibers are continuously produced, so that the lens gradually becomes larger and less elastic throughout life. The nucleus and cortex are made up of long concentric lamellae, the lens nucleus being harder than the cortex. Magnified view of lens showing termination of subcapsular epithelium (vertical section). These nuclei are evident microscopically in the peripheral portion of the lens near the equator and are continuous with the subcapsular epithelium. The lens is held in place by a suspensory ligament known as the zonule (zonule of Zinn), which is composed of numerous fibrils that arise from the surface of the ciliary body and insert into the lens equator. The lens consists of about 65% water, about 35% protein (the highest protein content of any tissue of the body), and a trace of minerals common to other body tissues. The trabecular meshwork is triangular in cross section, with its base directed toward the ciliary body. It is composed of perforated sheets of collagen and elastic 35 tissue, forming a filter with decreasing pore size as the canal of Schlemm is approached. The internal portion of the meshwork, facing the anterior chamber, is known as the uveal meshwork; the external portion, adjacent to the canal of Schlemm, is called the corneoscleral meshwork. The longitudinal fibers of the ciliary muscle insert into the trabecular meshwork. In most areas, the retina and retinal pigment epithelium are easily separated to form the subretinal space, such as occurs in retinal detachment. But at the optic disk and the ora serrata, the retina and retinal pigment epithelium are firmly bound together, thus limiting the spread of subretinal fluid in retinal detachment. This contrasts with the potential suprachoroidal space between the choroid and sclera, which extends to the scleral spur. Choroidal detachments thus extend beyond the ora serrata, under the pars plana and pars plicata. The epithelial layers of the inner surface of the ciliary body and the posterior surface of the iris represent anterior extensions of the retina and retinal pigment epithelium. It is known to anatomists as the area centralis, being defined histologically as that part of the retina in which the ganglion cell layer is more than one cell thick. The macula lutea is defined anatomically as the 3-mm diameter area containing the yellow luteal pigment xanthophyll. The histologic features of the fovea and foveola provide for fine visual discrimination, with the foveola providing 37 optimal visual acuity. The normally empty extracellular space of the retina is potentially greatest at the macula. Diseases that lead to accumulation of extracellular material particularly cause thickening of this area (macular edema). The foveola is supplied entirely by the choriocapillaris and is susceptible to irreparable damage when the retina is detached. The retinal blood vessels have a nonfenestrated endothelium, which forms the inner blood-retinal barrier, whereas the endothelium of choroidal vessels is fenestrated. The outer blood-retinal barrier lies at the level of the retinal pigment epithelium. The base of the vitreous maintains a firm attachment throughout life to the pars plana epithelium and the retina immediately behind the ora serrata. The remaining 1% includes two components, collagen and hyaluronan, which give the vitreous a gel-like form and consistency because of their ability to bind large volumes of water. The distance of structures from the limbus as measured externally is less than their 38 actual length. They are named according to their insertion into the sclera on the medial, lateral, inferior, and superior surfaces of the eye. The principal action of the respective muscles is thus to adduct, abduct, depress, and elevate the globe (see Chapter 12). The approximate distances of the points of insertion from the corneal limbus are: medial rectus, 5. Approximate distances of the rectus muscles from the limbus, and the approximate lengths of tendons. Oblique Muscles the two oblique muscles primarily control torsional movement and, to a lesser extent, upward and downward movements of the globe (see Chapter 12). It originates above and medial to the optic foramen and partially overlaps the origin of the levator palpebrae superioris muscle. The superior oblique has a thin, fusiform belly (30-mm long) and passes anteriorly in the form of a tendon (10 mm long) to its trochlea, or pulley. It is then reflected backward and downward as a further length of tendon to attach in a fan shape to the sclera beneath the superior rectus. The trochlea is a cartilaginous structure attached to the frontal bone 3 mm behind the orbital rim.

Much of what people typically oppose as eugenic concerns the notion of state-led blood pressure medication hydralazine discount lozol generic, coerced heart attack pathophysiology order lozol on line, strong or authoritarian eugenic programmes arrhythmia uti generic 2.5mg lozol otc, associated with sometimes ideologically-motivated efforts to minimise the incidence of certain traits in a population arteria doo purchase lozol on line. Understood in this way blood pressure 3020 order lozol 1.5mg with mastercard, certain interventions with eugenic outcomes that do not involve force or prejudice might be considered acceptable blood pressure medication cause weight gain buy cheap lozol 2.5 mg online, in some circumstances. Efforts to minimise these harms through the use of genetic technologies may be acceptable for similar reasons. However, advocates of liberal eugenics tend to argue that reproductive interventions that are capable of improving the genetics of future children are acceptable only when they are freely chosen by individual prospective parents, rather than when they are encouraged or imposed by the state. It could be argued for this reason that state supported public health goals to minimise genetic conditions or impairments through screening programmes should not be seen as unacceptable in all cases. See Goering S (2014) Eugenics, in the Stanford Encyclopedia of Philosophy, Zalta E (Editor), available at:://plato. Weak eugenics could be defined as promoting technologies of reproductive selection via non-coercive individual choices. Issues related to the expressivist objection, for example, may apply, since some disabled people may perceive either choices made by individual women and couples to terminate pregnancies following diagnosis of a fetal anomaly, or state-supported programmes to improve the genetic health of the population, as equivalent to efforts to prevent people like them existing, and thereby as hurtful, offensive or discriminatory (see discussion at Paragraphs 2. Either way, many of those who defend the use of prenatal screening and other reproductive interventions also concede that concerted and sustained efforts should be made to show that society values disabled people and to ensure that they are provided with the same opportunities as those without disabilities. These benefits may be particularly relevant to people with or who are carriers of an inherited genetic condition (see Paragraph 3. See also: McMahan J (2005) Preventing the existence of people with disabilities, in Quality of life and human difference: genetic testing, health care and disability, Wasserman D, Bickenbach J, and Wachbroit R (Editors) (Cambridge: Cambridge University Press). Such women should receive counselling with clinicians with expertise in prenatal screening, such as genetic counsellors. It has been recognised that the capacity of genetic counselling services must grow as more people access genetic testing services more generally. A medical termination involves taking medication to end the pregnancy and can be carried out at any stage of pregnancy. In 2015, 55 per cent of abortions were medical abortions, 40 per cent used the vacuum aspiration method and five per cent used D&E. Most of the women were offered only a medical termination, whereas most women who were offered a choice opted for a surgical method. Diagnostic testing requires experience on the part of the healthcare professional carrying out the procedure, and there is evidence to suggest that operators who perform procedures frequently have lower miscarriage rates. Such findings could include clinically relevant genetic information about the pregnant woman and maternal cancerous and malignant tumours. This might exacerbate existing challenges for healthcare professionals who have conscientious objections to prenatal screening. These include that doctors tell patients about their right to see another doctor who does not hold the same objection, ensure that their patient has enough information to exercise their right to see another practitioner, and that opting out of providing a test or treatment for a patient does not result in discrimination. International guidance says that licensing practices should not 261 Dheensa S, Shkedi-Rafid S, Crawford G et al. The aim of fetal anomaly screening to promote informed choice in pregnancy is not an aim to promote unlimited choice: it is to promote choice relating to information about significant medical conditions and impairments. The idea that public health policies should not aim to reduce the incidence of disability through screening has also been challenged. Other possible consequences include an increase in anxiety for women receiving high chance results. Recognising that there may be consequences of prenatal screening beyond those being aimed for, is important for the appraisal of the appropriateness of screening programmes. A better understanding of the factors at work would be helpful for ensuring women have access to the information and support they need to make informed choices. Some examples of criticisms of the criteria and how they are used to evaluate screening programmes are given below. Legally, the woman is the patient in pregnancy, but in some cases screening may be offered in order to improve outcomes for the fetus or future person. Enabling women to exercise their reproductive autonomy regarding termination has other consequences. Although few women report feelings of regret about a decision to have a termination following a diagnosis of fetal anomaly, such a decision is frequently described by pregnant women and couples as painful and distressing, which is not taken into account in current assessments. The criteria also do not specify whether the effective intervention must be one that is carried out prenatally, during birth or soon after birth. If the available intervention can be carried out during childhood or later, then there would be no need to screen prenatally for the condition. Given the range of views that tend to exist on prenatal screening programmes, a consensus is not likely to be possible, and a majority judgment is unlikely to be acceptable to 69 everyone. More important is an assessment of the ethical issues and how tensions between them might best be resolved (as we are attempting to do in this report). These included seeking expert input from established groups and making explicit the processes or expertise it has drawn on in reaching conclusions about social, ethical and legal issues. However, the cost of care of people with the condition being screened for should not enter into the equation for prenatal screening programmes, given that reducing the number of or eradicating disabled people in order to improve public health and reduce the burden on state resources cannot be a legitimate aim of prenatal screening (see Paragraph 2. It requires that public bodies have due regard to the needs to eliminate discrimination, advance equality of opportunity and foster good relations between different people when carrying out their activities. The factors that affect whether a prenatal screening programme meets the criteria can change over time, such as the cost or performance of the test, the availability of prenatal in utero treatment, the health and social prospects of people with the condition and public attitudes towards the screening programme. Again, it is not explicit or transparent how and when reviews of existing programmes take place. Decisions about what tests should be offered and to which patients are made on a case by-case basis by doctors such as clinical geneticists. Genetic counsellors and nurses are widely recognised as an integral parts of the multidisciplinary team. Arguments for not genetically testing a child in order to respect the autonomy and interests of the future adult also apply to not testing a fetus for adult onset conditions in a continuing pregnancy. Testing a fetus for carrier status generally has no immediate clinical use, and may undermine the autonomy and interests of the future person. Revealing information about the fetus that is of unknown or uncertain clinical significance could create unnecessary anxiety and lead more women to have invasive diagnostic procedures. This information would also have limited clinical utility, and may be harmful to the person that the fetus may become if it is stored and analysed later. Several of these tests are diagnostic and remove the need for invasive testing altogether. Women and couples with a family history of a genetic condition have a number of options available to them if they wish to avoid their biological children inheriting the condition. One option is to conceive naturally and perform genetic testing on the fetus once this is possible (this varies depending on the procedure). The evaluation takes into account the seriousness and prevalence of the condition, the purpose, performance, clinical utility and price of the test and any ethical, legal and social considerations. For each test, a clinical care pathway has been developed that outlines how the test should be offered and delivered. Someone with Apert syndrome has a 50 per cent chance of their children inheriting the condition. Both conditions can occur de novo, and there is a very small chance of recurrence. Where one parent or both parents has achondroplasia the chance of having a child with the condition is 50 per cent. Where both parents have achondroplasia there is also a 25 per cent chance of having a child who will be stillborn or die soon after birth. These are dominant conditions, with an overall incidence of 1 in every 2000-2500 live births. However, as services are commissioned locally, there is no guarantee an approval will automatically lead to funding of this test across the country as a whole. European guidelines for health professionals who are involved in prenatal diagnosis were published in 2014 by EuroGentest, a project funded by the European Commission to harmonise the process of genetic testing across Europe. The focus of the project was prenatal diagnosis for women who have an increased chance of having a fetus with a specific condition, rather than genetic screening of whole populations. The guidelines aim to provide a flexible framework for ethical clinical care and describe general principles, logistical considerations, clinical care and counselling topics in the context of prenatal diagnosis. This may be in advance of a pregnancy if a couple knows that any child they have will have a chance of a genetic condition. This may be because one of the parents is affected by a genetic condition, they have already had an affected child, or because they have a family history of the condition. A referral may also arise in the course of a pregnancy if problems are identified on an ultrasound scan, because of problems with maternal health, or if the couple becomes aware of a potentially relevant family history. Therefore, the two major groups of referred women and couples are those who already have a good knowledge of the condition in advance of having to make a decision, and those who are forced to make a decision very quickly under difficult circumstances. Decisions about what tests should be offered and to which patients are made on a case-by-case basis by doctors such as clinical geneticists. The criteria set out the circumstances in which testing should take place, such as the gestation of the pregnancy and the carrier status of the couple. The EuroGentest guidelines make recommendations related to the information and support that should be offered to women and couples undergoing any kind of prenatal diagnosis, including: Healthcare professionals involved in offering prenatal diagnosis must ensure they are informed and maintain their knowledge on all relevant aspects of prenatal diagnosis. The most recent guidance published in 2011 includes recommendations on seeking consent and, in particular, on communicating to patients the potential relevance of the results of genetic testing for other family members. The guidance also recommends the possibility of unexpected or incidental findings from genetic testing, and the routine practice of long term storage of samples for possible future analysis, should be discussed as part of the consent process. Women and couples are often already well informed about the condition if they have the condition themselves or it is in their family. Healthcare professionals involved in the delivery of prenatal genetic testing services tend to be appropriately skilled, and information is given in a timely and non-directive fashion. However, we did hear some reports of women being directed towards termination and a tendency for the focus to be on medical problems associated with the condition rather than information about day-to-day life. This can help women to make informed choices about termination or to prepare for the birth of a disabled child. It is possible that, in the future, more women with a family history of a genetic condition or with anomalous ultrasound scans may choose to have prenatal diagnostic testing if there is a safe, accurate test available that can be carried out early in pregnancy. Increased uptake may lead to an increase in the number of women receiving positive results, and thus an increase in both the number of women continuing a pregnancy and the number of women terminating a pregnancy. For example, an increase in the number of women deciding to continue their pregnancy would mean that more women had been able to prepare psychologically and practically for the birth of a baby with a genetic 296 Cordier C, Lambert D, Voelckel M-A, Hosterey-Ugander U and Skirton H (2012) A profile of the genetic counsellor and genetic nurse profession in European countries Journal of Community Genetics 3: 19-24. If an increase in terminations leads to a significant reduction in the number of people living with a condition, it is plausible that the quality of specialist health and social care received by people with the condition, and the importance attributed to research into the condition will be affected (see Paragraphs 2. People with a genetic condition may have a greater chance of having a child with a genetic condition that they may want to avoid. In some cases their own disability could make it more challenging for them to parent a disabled child themselves. Reasons given included because it would allow families to make informed decisions and it would prevent unnecessary suffering. Inheriting the homozygous version of the condition, which is usually fatal before or shortly after birth, was seen as something people would benefit from having the opportunity to avoid.

New drugs effective for migraine, including triptan, have been released one after another, but it is beyond dispute that the first step to treatment requires primarily an accurate diagnosis. When headache is regarded to be a pain in the head, doctors often casually diagnose functional headache due to a lack of sense of seriousness or urgency. However, it must not be forgotten that serious sequelae, even death, can result if the correct diagnosis of an organic headache is not made. Furthermore, even with this in mind, diagnosing a chronic headache is not simple, and even diagnosing a migraine may sometimes be difficult. Key words: Migraine; Tension-type headache; Cluster headache; Headache diagnosis with headache seems easy but is actually difficult. When we actually treat patients with treatment of an organic headache, which takes headache after having studied headache to an acute course, is beyond dispute, but also in some extent, we encounter incredibly many the case of a chronic headache like migraine cases which are puzzling. However, an accurate diagnosis in patients lives without question, and is important. This article is a revised English version of a paper originally published in the Journal of the Japan Medical Association (Vol. Excluding cases with acute or serious conditions, this form is completed while the patient is waiting, and can give easy and sys tematic general information on the age when When Consulted by a Patient with the headache started, family history, past his Chronic Headache tory, medication, character of the headache, It is a well known fact that the causes of aura, general condition including mental con headaches are diverse.

Gonococcal neonatal conjunctivitis causes corneal ulceration and blindness if not treated immediately. Chlamydial neonatal conjunctivitis (inclusion blennorrhea) is less destructive but can last months if untreated and may be followed by pneumonia. Treatment for neonatal gonococcal conjunctivitis is with ceftriaxone, 125 mg as a single intramuscular dose; a second choice is kanamycin, 75 mg intramuscularly. To treat chlamydial conjunctivitis in newborns, erythromycin oral suspension is effective at a dosage of 50 mg/kg/d in four divided doses for 2 weeks. Herpes simplex keratoconjunctivitis is treated with acyclovir, 30 mg/kg/d in three divided doses for 14 days. Other types of neonatal conjunctivitis are treated with erythromycin, gentamicin, or tobramycin ophthalmic ointment four times daily. Crede 1% silver nitrate prophylaxis is effective for the prevention of gonorrheal ophthalmia but not inclusion blennorrhea or herpetic infection. The slight chemical conjunctivitis induced by silver nitrate is minor and of short duration. Accidents with concentrated solutions can be avoided by using wax ampules specially prepared for Crede prophylaxis. The most common cause is cat-scratch disease, but there are many other causes, including Mycobacterium tuberculosis, Treponema pallidum, Francisella tularensis, Pasteurella (Yersinia) pseudo-tuberculosis, C trachomatis serovars L1, L2, and L3, and C immitis. Conjunctival Cat-Scratch Disease this protracted but benign granulomatous conjunctivitis is found most commonly in children who have been in intimate contact with cats. The child often runs a low-grade fever and develops a reasonably enlarged preauricular node and one or more conjunctival granulomas. The disease appears to be caused by a slender pleomorphic gram-negative bacillus (Bartonella [formerly Rochalimaea] henselae), which grows in the walls of blood vessels. With special stains, this organism can be seen in biopsies of conjunctival tissue. The organism closely resembles Leptotrichia buccalis, and the disease was previously known as leptotrichosis conjunctivae (Parinaud conjunctivitis). The organism is commonly found in the mouth in humans and always in the mouth in cats. The conjunctival nodule can be excised; in the case of a solitary granuloma, this may be curative. Systemic tetracyclines may shorten the course but should not be given to children under 7 years of age. Conjunctivitis Secondary to Neoplasms (Masquerade Syndrome) When examined superficially, a neoplasm of the conjunctiva or lid margin is often misdiagnosed as a chronic infectious conjunctivitis or keratoconjunctivitis. Since the underlying lesion is often not recognized, the condition has been referred to as masquerade syndrome. The masquerading neoplasms on record are conjunctival capillary carcinoma, conjunctival carcinoma in situ, infectious papilloma of the conjunctiva, sebaceous gland carcinoma, and verrucae. Verrucae and molluscum tumors of the lid margin may desquamate toxic tumor material that produces a chronic conjunctivitis, keratoconjunctivitis, or (rarely) keratitis alone. Readers are referred to other sections of this chapter for information about inflammatory and 254 degenerative lesions of the conjunctiva (eg, pingueculum and pterygium) that can simulate conjunctival neoplasms. They may enlarge slowly but have little or no invasive potential and no metastatic capability. Hamartomas are congenital tumors composed of normal or near normal cells and tissues that occur normally at that anatomic site but are present in abnormally excessive amounts. Choristomas are congenital cellular tumors consisting of normal cells and tissue elements that do not occur normally at that anatomic site. Conjunctival Nevus Conjunctival nevus is a benign neoplasm that arises from melanocytes, which exist normally within the basal layers of the conjunctival stratified squamous epithelium. It appears to be the most commonly encountered conjunctival neoplasm, but its exact incidence has never been calculated. It affects males and females equally, but it is almost exclusively a unilateral unifocal lesion. It is usually first noted during the first decade of life, but occasional lesions of this type do not become apparent until the teenage years or even later. Slitlamp biomicroscopy frequently reveals tiny intralesional cysts and fine blood vessels. The lesion can grow to over 5 mm in diameter and over 1 mm in thickness in some individuals, especially if it contains multiple microcysts. Conjunctival nevus of superior limbal and bulbar conjunctiva with variable intensity of melanotic pigmentation and microcysts visible in the less pigmented areas. It consists of a variety of cells and tissues of mesenchymal (mesodermal) origin, including fat cells, fibroblasts, and hair follicles. Unilateral unifocal lesions of this type frequently occur as isolated abnormalities, but bilateral limbal dermoids are usually a sign of Goldenhar syndrome. Small lesions of this type can usually be left alone, but larger ones that extend to or near the visual axis or cause pronounced irregular astigmatism are usually managed by penetrating or lamellar keratoplasty. Conjunctival Hemangioma 256 Conjunctival hemangioma is a hamartoma composed of conjunctival blood vessels. It is present at birth but may not become apparent until it enlarges and becomes more evident cosmetically. Unlike capillary hemangiomas of the eyelids and orbit, conjunctival hemangiomas rarely regress spontaneously. The principal indication for treatment is bothersome cosmetic appearance of the hemangioma, but no treatment has been shown to be both safe and effective. Attempted surgical excision can be complicated by difficult to control bleeding and incomplete removal that fails to improve or worsens the cosmetic abnormality. Cavernous hemangioma of conjunctiva, composed of large caliber blood vessels, some of which appear to extend into the underlying sclera. Conjunctival Lymphangioma Conjunctival lymphangioma is a hamartoma composed of dilated lymphatic channels lined by endothelial cells. Although congenital in nature, such lesions frequently do not appear until older childhood. They often enlarge abruptly during episodes of upper respiratory infection and may even fill with blood. Like conjunctival hemangiomas, these lesions are notoriously difficult if not impossible to eradicate by attempted surgical excision. If biopsy is performed, pathologic study may reveal benign cells, malignant cells, or cells that are judged to be borderline even by cytologic criteria. Tumors that cannot be classified unequivocally as either completely benign or definitely malignant are frequently referred to as premalignant or precancerous lesions. It rarely develops before middle age and becomes evident most often in older individuals. The crucial pathologic features are the degree of atypia of the melanocytic cells and the extent of conjunctival epithelial replacement by such cells. Conjunctival Dysplasia 258 Dysplasia of the conjunctival stratified squamous epithelium is a disordered growth and maturation of the epithelium that can be a precursor to squamous cell carcinoma (see later in this chapter). Lesions of this type are almost always unilateral and unifocal and appear at the limbus in the interpalpebral fissure. The typical lesion appears as an irregular off-white thickening of the limbal conjunctiva. Accumulation of keratin within the disordered cells sometimes results in focal leukoplakia (white patch of hyperkeratotic epithelium). Because such lesions cannot be distinguished clinically from squamous cell carcinoma, surgical excision is usually recommended. It occurs in middle-aged to older adults and is most evident in the corneal epithelium. It is frequently associated with one or more foci of conjunctival squamous cell carcinoma (see later in this chapter). It is usually managed by surgical removal of the visibly abnormal epithelial cells or topical therapy using mitomycin C, 5-fluorouracil, or interferon alpha-2b. Lymphoid Hyperplasia of Conjunctiva 259 Lymphoid hyperplasia of the conjunctiva is an infiltrative disorder of the conjunctival substantia propria in which the infiltrates are composed of mildly to moderately atypical lymphocytic cells. This lesion is generally regarded as borderline between benign inflammatory lymphoid infiltrates and malignant lymphoma (see later in this chapter). It affects both males and females, and it can be unifocal, multifocal, or diffuse in one or both eyes. If the lesion is prominent, incisional biopsy or excision is indicated to exclude malignant lymphoma. Some patients with lesions classified pathologically as lymphoid hyperplasia eventually develop extraophthalmic foci of systemic lymphoma, so patients with this type of conjunctival lesion are usually treated with relatively low-dose external beam radiation therapy to the affected eye or eyes and monitored periodically over the ensuing years for signs of systemic lymphoma. Invasive clinical and pathologic features are generally evident, and regional and distant metastases are potential sequelae. Squamous Cell Carcinoma of Conjunctiva Squamous cell carcinoma of the conjunctiva is an acquired malignant neoplasm composed of very atypical neoplastic cells arising from the stratified squamous epithelium. It usually affects middle-aged to elderly persons except in xeroderma pigmentosum, in which it tends to develop early in life. If neglected or particularly aggressive, conjunctival squamous cell carcinoma can invade the sclera and extend intraocularly, or invade the orbit. At the time of surgery, cryotherapy to the conjunctiva surrounding and the sclera 260 underlying the excisional defect is frequently performed to reduce the chance of local tumor recurrence. If clinical examination or pathologic study of the excised specimen suggests residual neoplasia, supplemental topical therapy with mitomycin C, 5-fluorouracil, or interferon alpha-2b is frequently provided. Leukoplakic type of squamous cell carcinoma of the limbal conjunctiva; the surface white plaque (leukoplakia) is a result of focal hyperkeratosis. Gelatinous type of squamous cell carcinoma of the limbal conjunctiva with prominent conjunctival blood vessels extending to the tumor. Papillary type of squamous cell carcinoma of the limbal conjunctiva with prominent conjunctival blood vessels extending to the tumor. It tends to be highly invasive and frequently extends into the orbit by the time it is diagnosed. Mucoepidermoid carcinoma of conjunctiva, manifesting as papillary type anteriorly and subepithelial nodule posteriorly. Conjunctival Melanoma Conjunctival melanoma is an acquired malignant neoplasm that arises from the intraepithelial melanocytes of the conjunctiva. It is almost exclusively unilateral but may be multifocal in some patients if it arises from pre-existing primary acquired melanosis (see earlier in this chapter). It affects both males and females with equal frequency, but it is much more common in Caucasians than in non-Caucasians. It can arise from any region of the conjunctiva (limbal, bulbar, forniceal, palpebral, or caruncular), but it is most common near the limbus in the interpalpebral area. It has the capability of invading the conjunctival stromal, extending into the conjunctival lymphatics, and metastasizing to regional lymph nodes in the head and neck and then to distant organs. Unfavorable prognostic factors for metastasis and metastatic death include larger tumor size, involvement of the fornix or caruncle, and local recurrence following attempted surgical excision. Treatment usually consists of wide surgical excision followed by conjunctival closure using sliding or 262 transposition flaps or a mucous membrane graft. Supplemental cryotherapy to the retained conjunctiva adjacent to the excisional defect at the time of surgical excision or subsequent topical therapy using mitomycin C, 5-fluorouracil, or interferon alpha-2b is frequently performed to reduce the likelihood of local tumor relapse. Regional lymph node dissection at the time of initial treatment should be considered in cases with high-risk features. A substantial proportion of patients with larger conjunctival melanomas that involved the fornix or caruncle at the time of treatment will eventually develop metastasis and die of that metastasis despite aggressive local therapy.
