[Analysis of 52 cases of retinal vein occlusion treated with laser photocoagulation]

41 of 52 cases of retinal vein occlusion (RVO) treated with laser photocoagulation were followed up for 3-30 months. Visual prognosis was good for patients of branch RVO, while visual improvement was not much for central RVO; however, the treatment could prevent or combat neovascularization and in turn neovascular glaucoma. Laser photocoagulation therapy of RVO was effective and few complications occurred if performed at an opportune time with an optimal wavelength or combination of wavelengths, and periodical follow-up and fluorescein angiography were useful in promoting the rate of successful operations.
