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。
This article explores the efficacy of early argon laser photocoagulation in retinal vein occlusion. Fifty-five eyes of 55 early-stage patients undergoing photocoagulation were divided into two groups: early-late photocoagulation group and late-stage photocoagulation group and late-stage photocoagulation group. The results showed that early photocoagulation could promote BRVO retinal hemorrhage absorption and shorten the course of disease (P <0.01) ; Reduce the incidence of vitreous hemorrhage caused by retinal neovascularization and neovascularization (P <0.05); this group in the improvement of macular visual function, reduce the incidence of macular edema and late photocoagulation group compared with no significant difference (P> 0.05), the reason to be explored. The authors suggest that BRVO, which has massive retinal hemorrhage, large area hypoxia and hypoxia, BRVO, which is a serious threat to macular visual function, or both, should be treated with photocoagulation as soon as possible in the case of clear interspace, Improve the prognosis.
