分析缺血性视网膜中央静脉阻塞３２眼经全视网膜光凝术后新生血管的改变情况。激光治疗前眼前部与眼后部新生血管的发生率无明显差异；激光治疗后部分病例视网膜新生血管消退，但眼后部随后产生新生血管。认为光凝只是调整了眼内新生血管的反应，并且完全消除视网膜缺血。
The changes of neovascularization in 32 eyes of central retinal vein occlusion after retinal photocoagulation were analyzed. There was no significant difference in the incidence of neovascularization between anterior eye and posterior eye in laser treatment. Retinal neovascularization subsided in some cases after laser treatment, but neovascularization was produced in the posterior eye. It is believed that photocoagulation only adjusts the response of intraocular neovascularization and completely eliminates retinal ischemia.
