ScleritisScleritisinflammation of the sclera caused chiefly by rheumatism, tuberculosis, brucellosis, or viral and other infections. It is marked by severe irritation of the eye, pain, and formation of an infiltrate in the sclera. Scleritis is often complicated by keratitis and iridocyclitis. In episcleritis, which is the inflammation of the outermost layers of the sclera, irritation is less pronounced and visual acuity usually remains unimpaired. Scleritis is treated with physiotherapy, antibiotics, and hormonal drugs and with local application of heat and corticosteroids. scleritisscleritis[sklĕ-ri´tis]scle·ri·tis(sklē-rī'tis),scleritis(sklə-rī′tĭs)scleritisOphthalmology Inflammation of sclera, most common in older adults Etiology Idiopathic, or associated with rheumatoid arthritis, Wegener's granulomatosis, metabolic disorders, infection, chemical or physical injuryscle·ri·tis(skler-ī'tis)scleritisInflammation of the SCLERA, usually as a feature of a general disease such as rheumatoid arthritis or as a complication of ophthalmic shingles (herpes zoster) or Wegener's granulomatosis.

About half the patients have one of the following diseases: rheumatoid arthritis, Wegener's granulomatosis, polyarteritis nodosa, systemic lupus erythematosus, or herpes zoster. It is characterized by pain, and white, avascular areas next to damaged areas through which one can see the brown colour of the underlying uveal tissue, and to congested areas of the sclera. In most cases visual acuity is decreased. The necrosis gradually spreads around the globe. Treatment typically consists of topical steroids, immunosuppressive agents and occasionally surgery to repair scleral or corneal perforation. See keratolysis; scleromalacia. scleritis necroticans See scleromalacia. posterior scleritis Inflammation of the sclera involving the posterior segment of the eye. The condition is often associated with a systemic disease (e.g. rheumatoid arthritis). It is characterized by pain and reduced visual acuity. The severity of the visual impairment depends on the involved tissue and its location. Signs include eyelid oedema, proptosis, limitation of ocular movements and, if anterior scleritis is present, redness. The ocular fundus may present disc swelling, choroidal folds, macular oedema and serous retinal detachment. Treatment consists mainly of systemic steroids and immunosuppressive agents. See choroidal folds. scleritis
