Abstract

To the Editor.  —We read with interest the article by the Macular Photocoagulation Study Group, "Persistent and Recurrent Neovascularization After Krypton Laser Photocoagulation for Neovascular Lesions of Ocular Histoplasmosis,1 " in the March 1989 issue of the Archives. Neovascularization persisted or recurred more frequently if treatment did not entirely cover the neovascularization or did not meet the required level of intense burn on the foveal side. Persistent neovascularization developed in 17% (17 of 102 eyes) of neovascular membranes (NVMs) that were completely treated, and in 39% (14 of 36 eyes) of NVMs that were incompletely treated.The authors emphasized that best results are obtained when the NVM is completely and intensely treated, implying that photocoagulation prevents recurrence of neovascular tissue by direct cauterization. However, Table 4 of their article notes that although 39% of incompletely treated NVMs persisted, 61 % of incompletely treated NVMs regressed! This implies that a successful outcome
