Objective
To investigate the method and effect of krypton laser photocoagulation for neovascularization in retinal vein occlusion .
Methods
Tweenty eight eyes of 27 patients with retinal vein occlusion with neovascularization were photocoagulated by krypton green and red laser.The fundus changes were observed by fundus fluorescein angiography after photocoagulation.
Results
The neov ascularization disappeared completely in 20 eyes and became smaller in 6 eyes,re mained no change in 2 eyes,and the visual acuity improved in 17 eyes (60.7%) after 6 monthes to 2.5 years of follow-up.
Conclusion
Krypton laser photocoagulation is obviously effective on regression of n eovascularization and prevenion of vitreous hemorrhage in retinal vein occlusion .
