The clinical observation to early krypton laser photocoagulation in the treatment of branch retinal vein occlusion and cystoids macular edema

Objective To evaluate the curative effect of laser photocoagulation in the treatment of branch retinal vein occlusion (BRVO) and cystoids macular edema.Methods A total of 85 patients (85 eyes) with branch retinal vein occlusion (BRVO) and cystoids macular edema diagnosed by fundus fluorescein angiography (FFA) were treated by laser photocoagulation with 3 class spot reaction.The period of follow-up was 12 months.The visual acuity, FFA, optical coherence tomography (OCT) were analyzed comparatively before photocoagulation and 1 month, 3 months, 6 months, 9 months and 12 months after photocoagulation.Results The visual acuity after photocoagulation of 1 month, 3 months, 6 months, 9 months and 12 months were improved 41 (48.24%) eyes, 62 (72.95%), 78 (91.76%), 76 (89.41%) and 80 (94.12%) respectively.The cured patients showed by FFA after photocoagulation of 1 month, 3 months, 6 months, 9 months and 12 months were 62(72.94%) eyes, 73 (85.88%), 77 (90.59%), 81 (95.29%) and 82 (96.47%) respectively.The thickness of RNL before treatment was (607.89± 176.31) um, while which at 1 month, 3 months, 6 months, 9 months and 12months after treatment were (502.72± 176.32) m, (420.15± 152.40) m, (352.13± 145.21) m, (348.21±138.56) m, and (325.82± 127.80) m respectively.Compared the RNL of the different periods of the post treatment and before treatment, the difference was significance (P <0.05).Conclusions Krypton laser photocoagulation is obviously effective on treatment of branch retinal vein occlusion and cystoids macular edema,and it is stable 6 months after laser photocoagulation.
