Objective: To evaluate the effect of extra-panretinal photocoagulation with argon laser for neovascular glaucoma indu ced by central retinal vein occlusion. Methods: Twelve cases (twelve eyes) of neovascular glaucoma were treated by extra-panretinal photocoagulat ion with argon laser. The average number of photocoagulation spots of each eye was 2 050. Results: After photocoagulation, the iris and anterior chamber angle neovascularizations of 8 cases disappeared. The IOPs of 4 cases became normal. Though the IOPs of another 8 cases were still high and anti-glaucoma medicines or other procedures were needed, the IOPS were much lower than that before laser treatment and the ocular pain and headache were disappeared or reduced.Conclusion: The extra-p anretinal photocoagulation appears to be the first choice for neovascular glauco ma induced by central retinal vein occlusion. The earlier and more extensive the photocoagulation is, the better the effect is.
