摘　　要：本文探讨了视网膜分支静脉阻塞早期氩激光光凝的疗效。55例早期患者58只眼依光凝时机早晚分早期光凝组及晚期对照组,观察6个月～2年,结果表明早期光凝可以促进 BRVO视网膜出血的吸收,缩短病程(P<0.01);降低视网膜新生血管及新生血管引起的玻璃体出血的发生率(P<0.05);本组在改善黄斑视功能、降低黄斑水肿的发生率方面与晚期光凝组相比差异无显著性(P>0.05),原因有待探讨。作者认为应该对有视网膜大量出血、大面积缺血缺氧的BRVO;对严重威胁黄斑视功能的 BRVO;或两种情况并存者;在屈光间质清晰的情况下,尽早施行光凝治疗,改善预后。The present article is a study of the therapeutic effect of argon laser photocoagulatiou on branch re- tinal vein occlusion(BRVO)in the early stage of the disease.Fifty-five cases(58 eyes)with BRVO of short duration were divided into an early photoco- agulation group and a late control group,and were followed up for a period of 6 months to 2 years.The results showed that early photocoagulation accelerated absorption of hemorrhages,thus shortening the cour- se of the disease(P<0.01),reducing the occurrence of retinal neovascularization and the consequent vitr- eous hemorrhages(P<0.05).In respect to impro- vement of the visual function of the macula and lo- wering of the occurrence of macular edema,there were no significant differences between the early and the late coagulation groups(P>0.05),a fact awaiting explanation.The authors hold that photoco- agulation should be done as early as possible in cas- es of BRVO with profuse hemorrhage,large areas of ischemia and anoxemia,or both these conditions,pr- ovided that the refractive media are clear enough, in order that a better prognosis can be expected.
