玻璃体后脱离对分枝静脉阻塞预后的评价

The effect of posterior vitreous detachment on the prognosis of branch retinal vein occlusion

目的:视网膜分枝静脉阻塞引起视力下降的两个重要并发症是:新生血管引起的玻璃体出血和持续性的黄斑水肿。本研究目的在于证明全玻璃体后脱离对视网膜分枝静脉阻塞预后的作用。方法:53例颞侧分枝静脉阻塞的病人平均随访18个月,详细记录所有病人的玻璃体情况,对伴有持续黄斑水肿、视网膜新生血管的病例做了统计学分析。结果:全玻璃体后脱离有明确的预防两个并发症的作用。结论:视网膜分枝静脉阻塞的所有病人都要做详尽仔细的玻璃体检查,是否有玻璃体后脱离,可以判断病情的预后。

Objective: To identify theroles of posterior detachment of total vitreous on the prognosis of retinal branch vein occlusion (BRVO), especially on its two important complications causing visual loss, vitreous hemorrhage due to retinal neovascularization and persistent macular edema.Methods: 53 patients with temporal branch vein obstruction were followed for 18 months on average. The vitreous conditions of all patients were established, and the effect on persistent macular edema and retinal neovascularization development was statistically investigated. Results: This prospective study shows that total posterior vitreous detachment has a clear preventive effect on both complications. Conclusions: Total posterior vitreous detachment shows a preventive effect on the two complications clearly. Careful vitreous examination in branch retinal vein occlusion is very important for the prognosis and the management.
