The pathology report also showed a A retrospective analysis of patients who graft-vs. However, a small number of familial localized (linear) scleroderma cases have been reported. Many consider localized scleroderma to be an immunologic disorder, since it is often accompanied by the presence of autoantibodies. Eosinophilia may be present, particularly during early active phases, and may correlate with disease activity. A polyclonal IgG and IgM hypergammaglobulinemia may also be present and is found more often with severe cases and with clinical progression. These include topical/intralesional/systemic glucocorticoids, antimalarials, etretinate, penicillin, D-penicillamine, phenytoin, vitamin E, griseofulvin, retinoids, interferon, calcitriol, and methotrexate. The treatment of this disease was simple and efficacious when recognized and initiated early. The epidemiology of morphea (localized scleroderma) in Olmsted County 1960-1993. It is thought to be exacerbated by overuse of topical preparations as well as over-cleaning.

The prevention of attack several years ago and later noticed progression of hyperpigmentation of the the beginnings of this brown color change. The discoloration is due to the leakage of blood from small blood vessels near the skin surface. The brown color is due to the hemosiderin deposits from the degradation of the extravascular erythrocytes. There are typically no symptoms, although some people can experience itching and discomfort. A novel approach to treatment is presented also, and includes a discussion of genetic counseling, psychological therapy, and routine full-body skin examinations.

The cells show high mitotic elastic capsule which is a semipermeable memactivity and form new cells which migrate towards brane. The centers of anterior and posterior surfaces are known as anterior pole and posterior pole, respectively. The consistency of the superficial part (cortex) of the lens is softer than the central (nucleus). The lens continues to grow throughout life and relative thickness of the cortex increases with age. The lens fibers develop from the lens epithelial cells the lens capsule is a transparent homogeneous and that continue to divide and get elongated and highly elastic envelope. They are mainly front than behind, the thickness being greater composed of proteins called crystallins. It is (nucleus of the lens), the newer ones occupy a secreted by the lens epithelium. The fibers of embryonic the lens epithelium is a single layer of cubical cells nucleus meet around Y-shaped sutures. The most peripheral part of the lens consists the lens epithelium has the highest metabolic rate of cortex (young lens fibers) and the lens capsule within the lens, it utilizes oxygen and glucose for (See Fig. Each fiber starts anteriorly and ends protein synthesis and transport of electrolytes, posteriorly. Suture lines, formed by the end-to-end carbohydrates and amino acids to the lens fibers. There are more than 2000 Normal lens contains approximately 66% water fibers in an adult lens. In in lens is about 20 mM and potassium about adults, lens is firm, transparent and avascular. The lens has higher levels of potassium the adult lens measures 5 mm anteroposteriorly ions and amino acids and lower levels of sodium and 9 mm equatorially and weighs about 255 mg. The sodium pump inserted onto the anterior and the posterior lens acts by pumping sodium ions out and taking capsule in a continuous fashion. The combination of active There are no blood vessels and nerves in the transport and membrane permeability is known lens. The sodium is pumped across the anterior surface of the lens into the aqueous humor and potassium moves from the aqueous into the lens. This arrangement results in a sodium-potassium gradient across the lens; potassium being higher at the front and sodium being higher at the back of the lens. Normally the intracellular level of calcium in the lens is about 30 mM while the extracellular calcium level is close to 2 mM. Congenital or Punctate, anterior polar, diffusion allows the waste products of the lens developmental posterior polar, central metabolism to leave the lens.

Traumatic Concussion injuries, changes in the lens are common and they often penetrating injuries result in the partial or complete loss of trans6. The Diseases of the Lens 253 etiology of many developmental cataracts is to alarm such patients about their lens opacities obscure. Heredity: A strong hereditary predisposition cular cataract wherein the capsule or the subis found in about 25% of all developmental capsular region of the lens is involved, and cataracts. Other infections such as cytomegalic Several forms of developmental cataracts are inclusion disease, toxoplasmosis and syphilis found, the relatively common ones are described can also lead to cataract formation. Toxic agents: Administration of corticosteroids Punctate cataract is very frequent in occurrence or thalidomide during pregnancy has cataracand manifests as multiple, small opaque dots, togenic effect. Nutritional deficiency: Deficiency states are On slit-lamp examination they appear as blue dots often incriminated in the causation of zonular hence known as blue-dot cataract or cataracta cerulea cataract. It consists of fine hemorrhage, endocrine dysfunction, and white powdery dots within the embryonic and inborn errors of metabolism have been infantile nuclei. The effects of infection, noxious agents, deficiency states or gene upon the developing lens Anterior Polar Cataract are indistinguishable and mainly depend on the the anterior polar cataract commonly occurs as a time of the insult. The most critical period in the single or multiple opacities in the anterior part of development of the lens lies between 5th and 8th the lens (Fig. The remnants of the anterior weeks of intrauterine life, when the cellular activity is maximal. Interference in the normal development during this period results in the formation of abnormal primary lens fibers leading to the development of central cataract. The involvement of secondary lens fibers during 8th to 16th weeks produces developmental cataract. Slight aberration in the development of lens fibers is common and, therefore, the lenses of most people show minute opacities especially when examined on slit-lamp under full mydriasis. The acquired form of anterior polar cataract occurs after perforation of a central corneal Central Nuclear Cataract ulcer wherein part of the lens capsule comes in In the central nuclear cataract, the opacities are mostly contact with perforated edges of the cornea. It is due Occasionally the opaque lens capsule projects to the inhibition of development of the lens during forwards into the anterior chamber like a pyramid, the first three months of gestation. The opacity is heterogenous, either dense in lens fibers grow between the capsular and cortical the center and rare in the periphery or vice versa. A progressive form of nuclear cataract is Posterior Polar Cataract associated with the rubella (German measles) infection in the mother in which the entire lens may be opacified the posterior polar cataract is characterized by as the virus causes necrosis of the embryonic nucleus. Slit-lamp examination reveals concentric rings around the central opacity (onionpeel appearance). The posterior polar cataract is usually associated with a thin posterior capsule or an occult posterior capsular defect. The posterior polar cataract may be associated with persistence of the anterior tunica vasculosa lentis. Mittendorf dot (also known as hyaloid corpuscle as it represents the attachment of hyaloid vessel to the posterior capsule) is a small white dot attached to the lens capsule inferonasally. It is usually stationary but the progressive form may appear which shows diffuse cortical opacities. Rubella is capable of producing gross ocular and systemic malformations such as microphthalmos, microcephaly, mental retardation, deafness, and patent ductus arteriosus. Sutural Cataract (Stellate Cataract) When opacities involve the sutures of the lens they are termed as sutural cataract or anterior axial embryonic cataract. The sutural cataract is almost always bilateral, and opacities often have branches and knobs projecting from them. It is characterized by an cataract accounting for nearly 50% of the total anteroposterior spindle-shaped opacity occurring developmental cataracts. The cataract is bilateral axially with off-shoots resembling a coral (Figs and may present at birth or manifest during early 16. Zonular cataracts, especially the bilateral ones, are usually inherited as an autosomal dominant trait. Congenital nuclear and sutural opacities of lens are often associated with zonular cataract. Maternal metabolic disturbances during pregnancy such as hypoparathyroidism may cause a zonular cataract. Disturbances of calcium metabolism, hypovitaminosis D (rickets) and defective development of enamel of permanent teeth may be associated with the zonular cataract. Zonular cataract causes variable visual impairment corresponding to the diameter and density of the affected lamella. The opacity affects a 256 Textbook of Ophthalmology particular lamella so that it encircles the nucleus (Fig. When is seldom affected, except when they are extensive viewed from front, lamellar cataract has a diskor associated with subcapsular cataract. The opacity is heterogenous and composed of dense and translucent areas, and occasionally the complete cataract may be unilateral or made up of small discrete dots. In complete cataract all the projections resembling the spokes of a cartwheel, lens fibers are opacified and retina cannot be popularly known as riders (Fig. Some cataracts are subtotal at birth and progress to become total and cause profound Coronary Cataract visual impairment. A group of club-shaped opacities in the cortex of Membranous Cataract the lens is known as coronary cataract. The opacities are situated around the equator of the lens Membranous cataracts are rare and occur due to encircling the central axis to form a crown or corona absorption of the lens fibers leaving the anterior Fig. The lens implantation surgery under one year of age is Treatment of Developmental Cataract controversial. Prevention of amblyopia: the risk of amblyopia the management of developmental cataract can be reduced by proper timing of surgery, requires a wide range of considerations including adequate aphakic correction, postoperative laterality, extent of opacity and visual impairment, care and management. The parents of the child small size of the eyeball, changing axial length of must be informed and educated that a a growing eyeball, lower scleral rigidity, more successful result of developmental cataract elastic capsule, high potential of development of surgery largely depends on proper aphakic amblyopia and frequent late complications of correction and continued amblyopic therapy. As most of the developmental cataracts are Prognosis stationary and do not cause visual impairment, the visual prognosis of unilateral congenital no treatment is required. The use of mydriatics and optical iridectomy are cataract because unilateral visual deprivation often considered obsolete procedures now-a-days. Bilateral congenital cataracts: Infants with congenital cataracts, associated with microbilateral congenital cataracts may develop phthalmos, persistent hyperplastic primary vitreous nystagmus at about 3 months of age due to or rubella retinopathy, also carry a poor prognosis. Therefore, cataract surgery must be performed on one eye Acquired Cataract as soon as possible, ideally prior to three months of age, followed by surgery on the the opacification of already formed lens fibers in fellow eye after 2-4 weeks. Unilateral congenital cataract: Infants with unilateral congenital cataract should be Etiology operated before 6 weeks of age to prevent Acquired cataract occurs due to degeneration of deprivation amblyopia. Correction of aphakia: (i) Spectacle phakic colloid system within the lens fibers or disrupts correction can be given after one week of surgery. However, older children with Longitudinal Study of Cataract have suggested a bilateral aphakia tolerate the spectacles well. They (ii) Contact lenses are a well-established method include advanced age, exposure to ultraviolet and of optical correction of monocular or binocular infrared radiations, hyperbaric oxygen, diabetes aphakia. Soft hydrophilic contact lenses for mellitus, dehydration due to diarrhea, and heavy extended wear are preferred. Deficiency states especially of vitamins E 258 Textbook of Ophthalmology and C, and carotinoids (antioxidants) expose the distortion of objects, polyopia, colored halos, and lens fibers to free radicals and enhance the effect of a variable degree of visual impairment. Glare or dazzling is common under bright light the role of inheritance in age-related cataract conditions. Genetic mutations in the night driving because the posterior subcapsular genes for crystallins and gap-junction proteins opacities obscure the pupillary aperture when cause cataracts in susceptible families. Ageing Changes in the Lens Distortion of objects occurs in the early stages of cataract formation due to changes in the refractive With advancement of age, the lens increases in indices of the lens fibers causing irregular refracweight and thickness and the nucleus undergoes tion. The proteins of lens Polyopia occurs due to an irregular refraction and fibers (crystallins) aggregate into higher molecular the patients often complain of seeing many moons weight proteins. Early cortical cataract does not cause any impairment Senile Cataract of vision while mature cortical cataract and posterior polar cataract lead to marked visual loss. Age-related cataract is by far the most common the patients with immature cortical cataract can variety occurring bilaterally often asymmetrically see better in day light but feel handicapped in in persons above sixty years of age. Senile cataract the patients with nuclear cataract have better is familial and shows a strong hereditary tendency vision in dimlight. In patients with Types lenticular sclerosis index myopia develops leading Senile cataract occurs in three forms: to deterioration of distant vision but the patient starts seeing better for the near and may even give 1. Senile Cortical Cataract Clinical Features Pathogenesis In the initial stage of cataract almost all patients remain symptom-free. Common symptoms of It is postulated that the senile cortical cataract cataract include glare, black spot before eyes, results from altered physiochemical processes Diseases of the Lens 259 within the cortex of the lens. The main processes involved in cataract formation are hydration, and replacement of soluble by insoluble proteins. Fine droplets of fluid and water cleft can be seen under the capsule on the slit-lamp in the initial stages of cataractogenesis. The initial process is reversible to some extent, but later the lens swells up and becomes opaque (intumescent). At this stage denaturation of protein of the lens fibers occurs, altering them chemically from non-coagulable to readily coagulable form. The clinical course of the development of senile cataract can be divided into 5 stages. Stage of lamellar separation or presenile change is characterized by the collection of fluid between the lens fibers resulting in lamellar separation which can be demonstrated on slit-lamp biomicroscopy.

If melanin deposits are found on the anterior surface of the iris treatment croup buy generic synthroid 25 mcg online, then there is a positive indication of the existence of serious metabolic disturbances medicine wheel buy synthroid master card. Indeed medications via peg tube best synthroid 100mcg, according to the accompanying signs in the iris treatment models 200mcg synthroid overnight delivery, one may speak of a pre-cancerous condition of the corresponding organs or systems which can ultimately lead to a cancerous state medications with weight loss side effects purchase generic synthroid pills. The iron-containing pigment: haemosiderin (haemofuscin) is a reddish colour to begin with symptoms of a stranger quality 200 mcg synthroid, and may then change towards dark brown (the colour change of a piece of rusting iron! On the destruction of large quantities of red blood corpuscles, this pigment becomes deposited within the tissues of the body. In my opinion it is not a sign for haemorrhagic tendencies, but only the sign of a large destruction of red blood corpuscles in which the iron is deposited in the tissues. However, it can also originate from protein metabolism without such regressive changes. Lipofuscin (never melanin) is a constituent of the extra-pyramidal system, In the Zona reticularis of the suprarenal body, lipofuscin can be recognised microscopically as a dark brown colouring in conditions of old age. Although lipofuscin is described as a product of old age, it can also exist as a degeneration product in young people and as a sign of exhaustion of particular organs, hence the terms: liver-, renaland pancreas-pigment. In my view, the duration of the condition can be assessed from the colour of the signs. Even though the above-mentioned pigments are topolabile, the presence of the flecks in the different zones of the iris can still be assigned to definite organ systems. If the light reddish pigment, as described in detail in the literature under the term-Nux vomica pigment, appears in the stomach and intestinal zone (first major zone), then it shows that a condition of fermentation affects these organs. If the discolouration extends outwards beyond the iris-wreath, then other organ systems can be affected. The yellow to brown deposits which extend from the iris-wreath to the outer margin of the iris (Berberis pigment) indicate general disease of the body (Maubach: Reibekucheniris). Indications of the acute phases of gout appear white, and generally lie next to dark signs in the bone area (fifth minor zone). The pigments described as liver-, renaland pancreas-pigment are likewise found in the ciliary zone. However, since the differences of colour and localisation of pigment-flecks are insufficient for diagnosis, one must look for other signs in the organ areas of the iris in order to reach a definite opinion. Iridologists have been concerned with iris pigment-signs from the first beginnings of irisdiagnosis, commencing with Liljequist and continuing with Attila von Peczely, Schnabel and Angerer. In spite of their extensive works, there still remains a wide field for further research. Therefore, all reactions and conditions of the pupil are to be considered basically as no more than changes affecting the inner margin of the iris. For the irisdiagnostician, however, only those abnormal conditions are significant which by paralysis or irritation of the nerves controlling the muscles of the iris; produce changes in the function or state of the pupil. It should lie in the centre of the iris (perhaps somewhat disposed towards the nasal side), and appear neither too large nor too small under ordinary conditions of lighting. On the whole, relatively larger pupils are found in small children, while in adults the size of the pupil progressively diminishes as old age advances. The pupil should not show any undue variation in width, and the movements of contraction and dilation should affect both pupils symmetrically. Classification of Pupillary Phenomena the pathological variations in the shape of the pupil may be divided into three groups 1. Deformations: (a) Oval distortion, (b) Segmental flattening of the margin, (c) Local outward bulging, (d) Local inward bulging, (e) Degeneration of the edge of the pupil. Variations in pupil diameter: (a) Miosis = symmetrical contraction of the pupils, (b) Mydriasis = symmetrical dilation of the pupils, (c) Anisocoria = inequality of pupils in size. Such oval pupils may have similar or dissimilar axes of inclination, which may occur at all angles. These deviations are principally classified as vertical, horizontal, inclined parallel to left or right, and as upper or lower diverging ellipses. Vertical ovals provide a sign of imminent sudden death (very shortly if the sign appears symmetrically in both irides, but at a longer interval if appearing in one eye only). Oblique oval pupils are seen in patients who have tendencies towards psychic disturbance, more severe depression, and even to suicide (see Disharmony line). If the vertical oval is to be considered as representing the effects of the head (brain) upon the lower half of the body, then the horizontal oval similarly illustrates the connection between the thyroid gland and the heart and lungs (angina pectoris with tendency to infarct, or asthma and respiratory paralysis, hormone influences). In general, one can probably say that in the majority of cases, oval pupils indicate hereditary or acquired predisposition to apoplexy. However, in viewing the iris, one must ensure that an apparently oval shape of the pupil does not arise from an oblique view on the part of the observer. Partial Deformations of the Pupils On the whole, these deformations consist of localised flattenings and bulgings of the margin of the pupil. In this case one should note whether these distortions appear in the right or left eye, and whether they are found in the upper, lower, nasal or temporal sectors. A sunken condition of a flattened segment leads to inward bulging, corresponding to an increase of all symptoms. All asymmetrical deformations of the pupil are reliable indications for assessing the condition of the nervous system, as well as to imply a disease condition of those organs whose areas are localised in the sector corresponding to the flattened segment. Flattening of the left pupil margin in the upper sector indicates psychic disturbances. Flattening of the lower sector of both pupils indicates severe muscle weakness affecting the legs. Flattening of the pupil margin in the nasal sector indicates disturbance arising from the spinal cord and its nerve trunks, and includes physical and mental conditions. From cerebellum to gonads, including suprarenals, pancreas and heart, these organs stand in close hormonal relationship. Flattening of the pupil margin in the upper sector of the right iris is more often seen in conditions associated with hysteria, whereas involvement of the same sector of the left iris indicates a predominance of melancholic states (see also right iris: Uterus-Cerebellum line, and left iris: Rectum-Cerebellum line). Right temporal sector flattening suggests disturbance of the liver and consequent effects. In this case, the patients are suffering from liver encumbrance arising from hereditary preconditions caused by faulty nutrition and mode of life 65 Pathological Degrees of Pupil Size An excessively contracted pupil is a sign for over-stimulation of the vegetative nervous system (vagotonia), whereas a widely dilated pupil indicates exhaustion of the vegetative nervous system (sympatheticotonia). The so-called Discolourations of the Pupil Since the pupil is merely a circular opening in the iris it cannot really be described as discoloured, but the underlying lens gives rise to the impression of colour change. Clinically, the grey discolourations (cataract) are to be distinguished from the green (glaucoma). The grey discolouration can assume very different shapes, which according to Angerer and Schnabel may have variable causes. In the case of green discolouration, it is necessary to distinguish primary and secondary glaucoma. Apart from these discolourations, signs of different shape may appear over the pupil. These may represent the remains of the foetal pupillary membrane, which originate from the iris-wreath as an irregular network of fine threads, and deposit as granules over the area of the pupil. One which is of delicate appearance, of reddish-brown colour and with a uniform edge, is to be regarded as normal. To enumerate the varieties of individual form and colour is beyond the scope of the present work. Any signs in the corresponding sector of the iris should be interpreted in association with all phenomena affecting the margin of the pupil. As stated elsewhere, signs which displace or break through the iris-wreath refer to the vegetative nervous system. If such signs go out from the pupil or go through to reach the pupil, they refer to the central nervous system. Where signs relating to the organ areas extend to the pupillary margin, an edgesign will be found. One must always bear in mind that the eye represents a unity, and should be considered in its entirety. From this it follows that neither the edge of the pupil nor the peripheral margin of the iris alone can provide the basis for any diagnosis.

Dilation of the iris-wreath in the area for ascending colon with indications of atrophy (Honeycomb signs). Contraction of the iris-wreath; in this case from a floating kidney (recognised by the arc formation of the white lines traversing the leg area). Thick white arc line as sign of inflammatory and exudative condition of the serous membranes. Loosening of the iris fibres and contraction of the iris-wreath in the kidney area. Several opened and closed lacunae in the respiratory organ areas and the kidney area. Small black oblong signs inside the iris-wreath indicating ulcerous processes in the duodenum, with signs of encumbrance affecting the gall-bladder, liver & pancreas. Heart lacuna, here displaced low because of the considerable dilation of the iris-wreath (Roemheld). Also to be observed is the general overlaying throughout the iris with white clouds and flakes (rheumatism). Oval pupil, & an almost unrecognisable 1st major zone, enables one to diagnose approaching death. The separation of the iris fibres & the distribution of dark spots over the whole of the ciliary zone can also be seen. Black loss-of-substance signs with white clouds in the middle of the ciliary zone. Transversales and angle-signs running from the outer rim inwards in the black area (injury).

Each successive journal improves and shows signs that our residents are being exposed to more and more variety and pathology in their residency programs. This will assure that our organization and the journal representing our organization continue to improve and cast a great reflection upon all of us. I feel like I just wrote my first letter stating my goals of being president and now I am writing my last letter as the outgoing president. We must always strive to make it better and never be content with the way things are. I have learned to be more tolerant of others and realize that everybody is doing the best they can, from where they are, with what they have. I took on this challenge and a by-product of this is that I feel great, I accomplish more on a daily basis and I look pretty darn good! It takes us to new levels where we can do even better and reach further then we ever thought possible. The best part of taking action and getting involved, is the self-satisfaction and personal growth that I have experienced. There are so many ongoing issues, and new ones popping up all of the time, that require our efforts. I thank my friends and mentors who have helped me have the life that I have today. Becky and Rick Mansfield and Marsha Wise run our organization efficiently and professionally. Sandy Goldman and my Physician Assistant Daughter Amy Gottlieb for picking up the slack this year when I was tied up doing other things.

Blood in a lacuna of the vitreous indicates a reasonable chance of anatomical success. Active tends to separate whereas blood in the gel clots and moves treatment is particularly indicated if the fellow eye is bodily with the gel itself. Vitreous Haemorrhage and Retinal Tears Ultrasonography with a B-scan is particularly helpful. Fresh haemorrhage within the vitreous cavity gives rise to Retinal tears crossing a blood vessel can lead to vitreous scattered point-like echoes of varying amplitude. This tends to occur in myopes and in those who tation of haemorrhage within the fuid vitreous produces a have predisposing degeneration of the retina.

About 3 months after the occlusion, capillary microaneurysms and fbrovascular proliferation may occur and vitreous haemorrhage may arise from the delicate new vessels. Vitreous Haemorrhage in Eales Disease Eales disease is an idiopathic, infammatory peripheral retinal vasculopathy which presents with recurrent vitreous haemorrhages in young males. It has been suggested that a hypersensitivity reaction of the retinal vessels to tuberculoproteins may be the cause of the vasculitis. The peripheral retinal vasculitis leads to obliteration of the affected vessels, particularly the shunt capillaries of the peripheral retina, which in turn produces hypoxia and fnally vasoproliferation. Haemorrhage generof the vessels, which leak copiously on fuorescein angiogally occurs from the preretinal fibrovascular fronds.

Initially these clear spontaneously, the presence of accompanying retinal detachment early but after a few recurrences, the haemorrhage organizes, vitreoretinal surgery is advised. Abnormal vessels An abnormality leading to opacifcation of the vitreous under traction should be treated with photocoagulation.

Once the visibility of the retina is restored, the cause for the vitreous disturbance is treated. Endophotocoagulation with a fbre optic probe delivering diode laser may be required to seal a retinal break or treat areas of retinal neovascularization. Vitrectomy is seldom carried out as an isolated procedure, but is often associated with surgery for vitreoretinal proliferation, complicated retinal detachments or foreign bodies in the eye. In the presence of vitreoretinal proliferation it is important to relieve all traction on the retina. Vitreous bands can be cut using the vitrectomy instrument or special miniature vitreoretinal scissors.

Summary the vitreous is a transparent gel which constitutes 80% of the volume of the globe and provides a clear optical medium behind the lens. Anatomy Normal Physiology of Axoplasmic Transport the optic nerve consists of approximately 1. Eighty per cent of then partially decussate and pass as the optic chiasma and the fibres of the optic nerve originate from the macular later the optic tract to terminate in the lateral geniculate body. Hence, diseases of the macula and optic nerve has a slow component (proteins and enzymes) that progresses can mimic each other. Retrograde axoplasmic ripheral nerves possess Schwann cells, fbroblasts and transport of lysosomes and mitochondria (from the brain to macrophages. As with white matter of the brain, the optic the eye) also occurs at an intermediate rate. The axons of the optic nerve acquire myelin sheaths proximal to the lamBlood Circulation of the Optic Nerve ina cribrosa and do not possess a neurilemma. Direct injury by penetrating trauma or indirect injury by concussional and rotational forces, and/or 6. Clinical Features Diseases affecting the optic nerve give rise to visual disturbances but can sometimes be asymptomatic and remain unnoticed (as in early papilloedema). Localization of a lesion producing visual disturbance to the optic nerve can almost always be made by careful clinical examination including visual acuity, colour vision, pupillary reactions, visual feld and ophthalmoscopic appearance of the optic nerve head. Sometimes visual disturbance in diseases affecting the optic nerve may be more subtle and may affect aspects of visual function other than visual acuity such as loss of contrast sensitivity, diminished stereoacuity and decrease in brightness of objects. Retinal diseases affecting the macula generally have normal pupillary reactions and an abnormal photostress test (see Chapter 10). Systematic Approach to Differential Diagnosis this can be made by categorizing the patient on the basis of: l Whether one or both eyes are affected l the pattern of visual field loss l the appearance of the optic nerve head or optic disc. Visual feld defects are best detected by Goldmann kinetic perimetry (full feld) and Humphrey automated centrocaecal scotomas (Fig. The feld defects caused by the appearance of the optic disc may be normal, swolvarious optic neuropathies are of different patterns but they len or oedematous, hyperaemic or pale, in different disorcan be broadly classifed as either (i) central (Fig. Swollen optic disc or disc oedema (true acquired disc papillomacular bundle) oedema must be distinguished from pseudo swelling) A.
