Argon Laser Photocoagulation in Ocular Histoplasmosis Syndrome

Argon laser photocoagulation was performed on 30 patients with ocular histoplasmosis syndrome involving the macula. Selection of patients for photocoagulation was dependent upon locating the sub-retinal neovascularization (SRNV) at least one vein-width removed from the capillary-free zone of the fovea on fluorescein angiography. Of the 30 treated patients, 27 maintained or improved visual acuity an average of 1 1/2 years following photocoagulation.
