The effects of acetazolamide on visual function in retinitis pigmentosa.

Purpose: To study the effects of acetazolamide on central and peripheral visual function in patients with retinitis pigmentosa (RP) who showed no evidence of macular edema.

Methods: Thirteen patients with retinitis pigmentosa participated in a preliminary study. Measures of central and peripheral visual function were obtained before and after an 8 wk period on acetazolamide.

A multicenter study of Pneumocystis choroidopathy.

We studied 21 patients with the acquired immunodeficiency syndrome and presumed Pneumocystic carinii choroidopathy. The lesions were characteristically yellow to pale yellow in color, appeared at the level of the choroid, and were found in the posterior pole. They varied in size from 300 to 3,000 microns, initially increasing in number before treatment and eventually resolving after systemic antimicrobial therapy.
