Abstract:AIM: To study the clinical curative effect argon chlorine laser treatment in branch retinal vein occlusion(BRVO).
METHODS:The 60 BRVO patients clinically confirmed by fundus fluorescein angiography(FFA)were randomly divided into 2 groups: group A(treatment group)30 cases underwent argon chlorine laser photocoagulation; group B(control group)30 cases were for activating blood circulation and eliminating stasis drugs(compound thrombosis the capsule)). The results of visual acuity and macula edema regression in the two groups 6 months after treatment were compared.
RESULTS: Group A: obviously effective in 8 cases, effective 20 cases. Group B: obviously effective in 2 cases, effective in 14 cases, invalid in 14 cases; Group A had 14 cases combined with macular edema, and after argon chlorine retinal photocoagulation, macular edema disappeared in 12 cases, not retreat in 2 cases; Group B had 13 cases combined with macular edema, and macular edema disappeared after medical treatment in 3 cases, not disappeared in 10 cases.
CONCLUSION:The argon laser photocoagulation is an effective treatment for BRVO, promote the visual acuity, shorten the duration of symptoms.
