Photocoagulation in retinal vein occlusion.

Photocoagulation was used to treat 40 eyes, 20 with central and 20 with branch vein occlusion. Panretinal photocoagulation was used over the fundus in central vein occlusion, and regional photocoagulation over the affected area in branch vein occlusion. No complications were observed during a follow-up period of 8 to 24 months. Recent as well as long-standing cases with macular edema were treated. Visual acuity improved in 85% of eyes with central vein occlusion and 80% of eyes with branch vein occlusion. Visual acuity results were more satisfactory with early treatment.
