  • Look Inside

We reviewed 24 eyes of branch retinal vein occlusion (BRVO) with cystoid macular edema (CME) . The series comprised 14 eyes which received scatter photocoagulation within 6 months of onset and 10 eyes whch did not.The CME persisted for an average of 23.75±4.54 months in the former group and 11.30±4.54 months in the latter.CME thus lasted longer after scatter photocoagulation than the rest (p = 0.0443) and particularly in eyes which received larger number of coagulation spots.The 1og MAR visusal acuity after resolution of CME averaged 3.57±4.65 in photocoagulated eyes and 1.72±2.63 in the others. There was no difference between the two groups (p=0.27). The findings show that scatter photocoagulation may be effective in preventing late complications of BRVO but that it may induce persistent CME when performed early.
