Posterior scleritis

Abstract

Posterior scleritis must be considered in the differential diagnosis of many ocular conditions, including angle closure glaucoma, choroidal folds, optic disk edema, circumscribed fundus mass, choroidal detachment, and exudative retinal detachment. Because it is rare, a high index of suspicion is necessary. Anterior scleritis, pain, or a history of collagen-vascular disease, when present, help to alert the clinician to the correct diagnosis. Posterior scleritis affects women more often than men, but annular ciliochoroidal effusion and choroidal folds are more common in men. Exudative macular detachment and a circumscribed fundus mass are more common in women. This paper reviews the world literature on posterior scleritis and describes findings in a series of 43 patients seen at Wills Eye Hospital. It stresses the clinical features and ancillary diagnostic tests that help to establish the diagnosis.
