An opacity develops at the margin of the cornea Necrotizing scleritis without infammation is called near the affected scleral area; it is approximately triangular scleromalacia perforans (Fig. Concurrent therapy with antacids or H2-receptor blockers such as ranitidine 150 mg given twice daily orally or famotidine 20 mg twice daily orally is advisable. In patients with necrotizing scleritis, systemic steroids and immunosuppressives are recommended. Scleral patch grafting may be necessary if there is any signifcant risk of perforation.

Posterior Scleritis Infectious causes, if identifed, are treated with appro this is an infammation with thickening of the posterior priate topical and systemic antimicrobial agents. Panoph sclera which may start primarily posteriorly or may be an thalmitis, if severe, will warrant intravenous antibiotics in extension of anterior scleritis. The clinical presentation is varied and the diagnosis is easily missed, particularly in Specifc Infammatory Diseases associated cases with no pain or no anterior segment involvement. Posterior Collagen Vascular Diseases vitiates, disc oedema, macular oedema, choroidal folds, Scleral involvement is common in this group of disorders, choroidal detachment, uveal effusion syndrome and exuda particularly in rheumatoid arthritis.

A more serious condition is necrotizing Chapter | 16 Diseases of the Sclera 229 nodular scleritis in which a violent and painful anterior eye with an incarceration of the uveal tissue. The basic scleritis, often circumferential in its extent, characterized underlying pathology is a weakening of the eye wall, which by extensive swelling and the appearance of one or more can be caused by many infammatory or degenerative yellow nodules, usually proceeds to necrosis leading diseases involving these structures. Most commonly the eventually to disintegration of the sclera and exposure diseases causing a weakening of the globe are accompanied of the underlying uvea (Fig. In scleromalacia per by a raised intraocular pressure and both contribute to the forans a similar necrosis of the sclera occurs with expo development of the staphyloma. Depending on the site affected, staphyloma can be Finally, in massive granuloma of the sclera, prolifera classifed as (i) anterior, (ii) intercalary, (iii) ciliary, tive changes are predominant. In all these Anterior Staphyloma cases, serious and often destructive extension occurs into the uveal tract, and the general prognosis is poor. This can be partial or total, depending on whether part or Systemic treatment by corticosteroids offers the only whole of the cornea is affected. Gradually the weak anterior this used to be seen in tertiary syphilis but is now surface of the eye protrudes outward leading to an anterior uncommon. Tuberculosis Intercalary Staphyloma this form of scleritis may be secondary, due to an extension this is located at the limbus and is lined by the root of from the conjunctiva, iris, ciliary body or choroid. It is also be primary, forming a localized nodule which caseates seen externally from the limbus to up to 2 mm behind and ulcerates.

Suppurative Bacterial Infections Virulent organisms such as Pseudomonas causing an endo phthalmitis may spread to infect the sclera and episcleral tissue, leading to a panophthalmitis including a scleritis. Extension of such infection is clinically diagnosed by the development of painful eye movements due to infamma tion involving the muscle sheaths at the point where they are inserted onto the sclera. Treatment consists of high doses of intravenous broad-spectrum antibiotics and a care ful watch for further spread into the orbit and subsequent cavernous sinus thrombosis. Surgical measures include in travitreal injection of antibiotics, vitrectomy and, fnally, evisceration of the globe if the eye has no light perception and all measures to contain the infection fail. Here the ciliary body is incarcer ated in the region of scleral ectasia and has a bluish colour with a lobulated surface.
