Radial Optic Neurotomy for Central Retinal Vein Occlusion

When several and very different treatment modalities exist for one ailment, it usually means that none of them is generally effective or superior to others. Central retinal vein occlusion (CRVO) is a condition for which various types of management have been proposed. However, the only standard care suggested by the Central Vein Occlusion Study Group (CVOSG) is panretinal photocoagulation when the condition is complicated by iris neovascularization.

Herein, we present the opposing views of two vitreoretinal specialists regarding this issue.
