Efficacy of panretinal photocoagulation in central retinal vein occlusion

This retrospective study reviews the efficacy of panretinal photocoagulation in the prevention and management of ocular neovascularization in 55 cases of central retinal vein occlusion. Differentiation of occlusions into ischemic and nonischemic forms is of critical importance, with aggressive laser treatment being warranted in the ischemic variety. The presence of ocular neovascularization may not necessarily imply a grim prognosis.
