目的观察早期(10～30 d)全视网膜光凝(panrentinal photocoagulation,PRP)治疗缺血型视网膜中央静脉阻塞(CRVO)的疗效.方法选择伴有后极部大量出血的缺血型视网膜中央静脉阻塞患者27例(27只眼),其中治疗组12例(12只眼),对照组15例(15只眼).对照组于发病后3～6个月内进行常规激光治疗,每周1次,4次完成全视网膜光凝(PRP)；治疗组于发病后10～30 d内,先行2次周边部分视网膜光凝治疗,待出血吸收后,逐步进行至全视网膜光凝术.两组患者于PRP治疗结束后1个月进行视力、眼底、眼压、OCT检查,3个月时行眼底视网膜荧光血管造影.结果治疗组中,视力提高10例(83.3％),无变化1例(8.3％),视力下降1例(8.3％),总有效率91.6％.2～4个月后极部出血大部分吸收.对照组中,视力提高8例(53.3％),无变化l例(6.7％),视力下降6例(40.0％),总有效率60.0％,2～6个月后极部出血大部分吸收.结论对于伴有后极部出血较多的缺血型视网膜中央静脉阻塞患者,采取早期、间隔式全视网膜光凝术在有效地治疗该病的同时,可以缩短治疗周期,减少并发症的发生.

Objective To observe the effect of earlier period retina photo coagulation on ischemia central retinal vein obstruction (CRVO). Methods Twenty-seven cases were chosen who had the ischemia CRVO with huge hemorrhage at the posterior pole of the retina,15 cases as the control group and 12 cases as the treatment group.In the control group,the routine method was used to take retina photo coagulation every week and last for 4 times in 3～6 months after they caught the disease.In the treatment group,retina photo coagulation was performed twice in 10-30 days after they caught the disease.After the hemorrhage was absorbed,the retina photo coagulation was used again.The two groups had the routine ocular examination in one month and FFA in 3 months after the treatment. Results In the treatment group,visual acuity were increased in 10 cases (83.3％),steady in 1 case (8.3％),decreased in 1 case (8.3％),the total effective rate was 91.6％.In the control group,visual acuity were increased in 8 cases (53.3％),steady in 1 case (6.7％),decreased in 6 cases (40.0％),the total effective rate was 60.0％.The period that the hemorrhage was absorbed is 4 months in the treatment group and 6 months in the control group. Conclusions The therapeutic effect of using pre-earlier period and interval retina photo coagulation to treat these patients who caught ischemia-CRVO with huge hemorrhage at the posterior pole of the retina is obvious,it can shorten the treatment cycle and reduce the incidence of the complications.
