Abstract

We studied 124 consecutive eyes that had laser photocoagulation for choroidal new vessel membranes (NVM) associated with pigment epithelial detachment (PED). In many cases, the extent of the NVM was uncertain. We thought it was not subfoveal in all cases but it possibly may have been subfoveal in one subgroup of cases. With a mean follow-up of 16 months, vision was stable or improved in 53% of the treated eyes. There was no difference in outcome between argontreated and krypton-treated eyes. On the basis of fluorescein angiograms, we classified 86 of the eyes into four nonexclusive groups. Vision was stable or improved in 68% of eyes with juxtafoveal or extrafoveal PED, 48% with subfoveal PED, 76% with juxtafoveal or extrafoveal NVM, and 50% of eyes with possibly subfoveal NVM. A randomized clinical trial of laser photocoagulation for NVM in PED is both indicated and warranted. A pilot study under the auspices of the Macular Photocoagulation Study is now under way to determine the feasibility of and develop a protocol for such a trial. RETINA 8:115-121, 1988
