氪红激光早期光凝治疗视网膜分支静脉阻塞的疗效评估

Treatment efficacy of krypton-red laser on early stage of branch retinal vein occlusion

目的 对视网膜分支静脉阻塞视网膜光凝术的早期与晚期治疗进行疗效评估。 方法 将88例视网膜分支静脉阻塞患者分为3个月内光凝治疗早期组和3个月后光凝治疗晚期组。2组病例均配合常规的药物治疗,光凝后随访6～18个月,观察2组治疗后视力、荧光素眼底血管造影(FFA)检查及光学相干断层扫描(OCT)图像分析。 结果 早期组视力恢复至0.6以上者26例,占56.5％,9例恢复至1.0以上,无1例<0.1者。晚期治疗组视力<0.1者达10例,视力恢复至0.6以上者11例,占26.1％。2组随诊结果显示,甲期治疗组视力显效明显优于晚期治疗组. 结论 早期治疗组效果明显优于晚期治疗组。视网膜静脉阻塞应采取早期激光治疗,以促使视网膜出血、渗出、水肿尽快吸收,这对于改善视力预后有重要意义。

Objective To compare the effect of krypton-red laser on branch retinal vein occlusion in the early stage and for the extended period. Methods Eighty-eight cases with branch retinal vein occlusion were divided into the early and the extended treating group. They were treated with the krypton-red laser at different time. The changes of fundus, fundus fluorescein angiography( FFA) and optical coherence tomography ( OCT) were analyzed following laser treatment. All of the eyes were followed up for 6 - 18 months. Results The visual acuity of photocoagulative cases in the early stage got significantly improved as compared with the extented group. Conclusion The treating efficacy in early stage cases are better than that of the longer period ones. The branch retinal vein occlusion should be treated as early as possible .
