目的探讨不同治疗方法对视网膜黄斑分支静脉阻塞(MBRVO)患者预后视力影响。方法选取2012年1月-2014年12月间在本院经荧光素眼底血管造影(FFA)确诊为MBRVO患者200例,分为试验组(n=87)常规药物加激光治疗,对照组(n=113)常规药物治疗,分析不同治疗方法对MBRVO患者预后的影响。结果患者阻塞支别情况为:黄斑第一分支185例(92.50%);黄斑第二分支15例(7.50%);黄斑第三分支例数为0。88例患者出现阻塞区毛细血管闭塞和中心凹毛细血管拱环部分破坏,比例为44%;70例患者有侧支循环形成,比例为35%;18例患者出现黄斑囊样水肿,比例为9%。治疗后试验组患者视力恢复临床有效率(50眼,57.47%)高于对照组临床有效率(38眼,33.63%),差异有统计学意义(χ~2=7.642,P<0.05)。结论常规药物治疗联合激光术对MBRVO患者预后视力临床疗效较好,可减轻患者黄斑水肿,同时改善患者视力,值得临床关注。
Objective To investigate the influence of different treatment methods on the prognosis of patients with macular branch vein occlusion (MBRVO). Methods 200 patients with MBRVO diagnosed by fluorescein fundus angiography (FFA) in our hospital from January 2012 to December 2014 were selected and divided into experimental group (n = 87) and conventional therapy plus laser treatment. The control group (n = 113) conventional drug treatment, analysis of different treatment methods on the prognosis of patients with MBRVO. Results The patients with obstruction included 185 cases of first branch of macula (92.50%), 15 cases of second branch of macula (7.50%), 0.88 cases of third branch of macula, occlusion of capillary occlusion and center Partial destruction of concave capillary arch ring, the ratio was 44%; 70 patients had collateral circulation, the proportion was 35%; 18 patients macular cystoid edema, the ratio was 9%. The clinical effective rate (50 eyes, 57.47%) in the test group was higher than that in the control group (38 eyes, 33.63%). The difference was statistically significant (χ ~ 2 = 7.642, P <0.05). Conclusion Conventional medical therapy combined with laser surgery in patients with MBRVO better prognosis of visual acuity clinical curative effect, can reduce macular edema, while improving visual acuity in patients, deserved clinical attention.
