方法：将50例视网膜静脉阻塞患者随机分成两组：治疗组(药物治疗)和联合治疗组(药物及激光治疗)，各25例，观察玻璃体积血的发生率。

结果：治疗组发生玻璃体积血的病例数明显高于联合治疗组。

结论：注重造影检查，应用药物联合激光光凝治疗对防止基层医院视网膜静脉阻塞致玻璃体积血有明显的治疗作用。

METHODS: Totally 50 patients with retinal vein occlusion were randomly divided into treatment group(drug therapy)and combined treatment group(drugs and laser treatment), each 25 cases, the occurrence of vitreous hemorrhage, number of cases, and the restoration of vision were observed.

RESULTS: The number of cases with vitreous hemorrhage in treatment group glass volume blood was significantly higher than that in drug combined with laser photocoagulation group.

CONCLUSION: Pay attention to imaging, drug combined with laser photocoagulation in treatment of vitreous hemorrhage caused by basic-level hospital retinal vein occlusion has obvious prevention effect.
