Macular serous exudation in patients with acquired immunodeficiency syndrome and cytomegalovirus retinitis.

Abstract

Central visual loss in cytomegalovirus retinitis in patients with acquired immunodeficiency syndrome (AIDS) occurs in two forms: direct macular tissue destruction and secondary involvement as part of rhegmatogenous retinal detachment. We treated 32 patients (35 eyes) with macular exudation that caused reversible visual loss and initially manifested as neurosensory retinal detachment and lipid exudates. Of 35 eyes, 25 showed papillary or peripapillary active retinitis and ten showed retinitis 1,500 to 3,000 microns from the fovea. Of 23 eyes with reduced vision that were followed up until healing of the retinitis and resolution of subretinal fluid and lipid exudates, 22 (96%) showed visual improvement with anti-cytomegalovirus treatment. Our findings suggest that macular exudation is a reversible cause of visual loss in patients with cytomegalovirus retinitis.
