To explore and analyze the therapeutic effect of argon laser photocoagulation for the retinal neovascularization in retinal vein occlusion, argon laser potocoagulation (200 to 500 μm spot sizes; 0 1～0 2 second; 0 12～0 4w; grade I; blue-green wavelength) were given to 55 cases of the retinal neovascularization in retinal vein occlusion. Central retinal vein occlusion was treated with panretinal photocoagulation. Branch retinal vein occlusion was treated with regional disseminated photocoagulation. Photocogulation(100 μm spot size; 0 1 second; gren wavelength ) for macula was used in a grid pattern. The pwer used was set according to diseases, not beyond the power causing reaction of grade I. Result: Among the 55 cases, 44 cases were effective. Total effective rate of regression of neovascularization was 80%. Eleven cases were of no effect ( including 8 cases with neovascularization on optic disc, 3 cases with simple retinal neovascularization). Visual asuity were improved in 18 cases (32 7%), maintained in 34 cases (61 8%), declined in 3 cases ( 5 5%). Conclusion: The final prupose of argon laser photocoagulation, for the retinal neovasculavization in retinal vein occlusion is to regress neovascularization, prevent vitrous and retinal hemorrhage and its complications, reduce or prvent macula edema, and retain residual visual capacity.
