Abstract

I read with great interest the article published by the Central Vein Occlusion Study Group1 in the August 1993 issue of the Archives.

This report stimulated me to ask some questions. Group M includes eyes with macular edema involving fovea, which was confirmed by the Reading Center based on fundus fluorescein angiography. Taking into account that the Early Treatment Diabetic Retinopathy Study Research Group2 achieved an exact quantification of macular edema by means of stereoscopic fundus photography, I would like to know why a similar technique has not been used to evaluate macular edema in group M.

Furthermore, the study does not specify if the cases of macular edema associated with ischemic maculopathy will be separated. Is it possible that, as in cases of diabetic retinopathy, the presence of ischemic maculopathy does not allow a grid-pattern photocoagulation because this laser treatment may cause further perifoveal microcirculation damage?
