Krypton yellow laser photocoagulation treatment of branch retinal vein occlusion

Objective To investigate the effect of krypton laser photocoagulation on branch retinal vein occlusion. Methods All of 56 patients with branch retinal vein occlusion were photocoagulated by krypton laser. The patients were followed up for 5 to 32 months. The fundus changes and complications were observed by fundus fluorescein angiography after photocoagulation. Results The visual acuity improved in 35 eyes(62 5%). The visual acuity surpassed 0 5 in 29 eyes(51 78%) after photocoagulation. Macular edema disappeared completely or reduced in 39 eyes(76 42%) after photocoagulation. Conclusion Krypton laser photocoagulation is obviously effective on treatment of branch retinal vein occlusion.
