A randomized clinical trial of early panretinal photocoagulation for ischemic central vein occlusion. The Central Vein Occlusion Study Group N report.

Abstract

Prophylactic PRP does not totally prevent TC-INV/ANV, and prompt regression of TC-INV/ANV in response to PRP is more likely to occur in eyes that have not been treated previously. The authors recommend careful observation with frequent follow-up examinations in the early months (including undilated slit-lamp examination of the iris and gonioscopy) and prompt PRP of eyes in which TC-INV/ANV develops.
