It is important to recognize the distinguishing features between posterior scleritis and choroidal melanoma. In a report on 137 patients with posterior scleritis, McCluskey and coworkers8 and Calthorpe et al9 found that 65% of them were female and 29% had an associated systemic condition. The most common symptoms were those associated with anterior scleritis (60%), pain (56%), and poor vision (31%). The most common signs were serous retinal detachment (21%), optic nerve swelling (18%), and circumscribed fundus mass (13%).8,9 It is noteworthy that our patient had no symptoms or associated collagen vascular disease. The only finding was nonpigmented fundus mass with minimal subretinal fluid. We believe that the nonpigmented appearance of the lesion, normal intrinsic choroidal vascular pattern, and transmission of light on transillumination were important clinical clues suggestive of posterior scleritis.
