目的 探讨玻璃体后脱离对视网膜分支静脉阻塞 (branch retinal vein occlusion,BRVO)预后的影响。 方法 回顾性分析 116例经荧光素眼底血管造影 (fundus fluorescein angiography,FFA)检查确诊的 BRVO患者 116只患眼初诊时玻璃体检查结果与随访 (10 .7± 2 .2 )个月时形成新生血管、发生黄斑水肿的临床资料 ,探讨玻璃体条件与眼后节新生血管形成、黄斑水肿的关系。 结果 FFA检查 116只患眼中40只眼为缺血型改变 ,其中 2 5只无玻璃体后脱离或部分性后脱离眼中 ,12只眼发现视网膜或 (和 )视盘新生血管形成 ,占 48.0 % ;15只完全性玻璃体后脱离眼中只有 1只眼产生新生血管 ,占 6 .7% (P<0 .0 5 )。 116只患眼中 45只眼发生弥漫性黄斑水肿 ,占 38.8%。视网膜黄斑粘连者黄斑水肿发生率为 5 1.5 % ,显著高于视网膜黄斑分离者 (2 2 .0 % ) (P<0 .0 1)。 结论 完全性玻璃体后脱离对 BRVO发生眼后节新生血管和黄斑水肿具有一定阻止效应。
Objective To investigate the effect of vitreous detachment on the prognosis of retinal branch retinal vein occlusion (BRVO). Methods One hundred and sixty-six eyes of 116 BRVO patients diagnosed by fundus fluorescein angiography (FFA) were retrospectively analyzed. Results of vitreous examination at the time of first visit were followed up (10.7 ± 2.2) months to form neovascularization , The occurrence of macular edema clinical data to explore the relationship between vitreous conditions and ocular neovascularization, macular edema. Results Forty-one eyes of 116 eyes with FFA were ischemic. Forty-five eyes with posterior vitreous detachment or partial posterior detachment showed retinal or / and optic disc neovascularization in 12 eyes (48.0%). 15 Only complete vitreous detachment from the eyes of only one eye angiogenesis, accounting for 6.7% (P <0.05). Of the 116 eyes, 45 had diffuse macular edema, accounting for 38.8%. The incidence of macular edema in macular adhesions was 51.5%, significantly higher than that in macular separators (22.0%) (P <0.01). Conclusion Complete posterior vitreous detachment has a certain preventive effect on the occurrence of ophthalmodeal neovascularization and macular edema in BRVO.
