激光格栅样光凝治疗视网膜中央静脉阻塞致黄斑囊样水肿的分析

Analysis of grid photo-coagulation in treatment of macular vesicular edema caused by central retinal vein occlusion

目的:分析格栅样光凝治疗视网膜中央静脉阻塞致黄斑囊样水肿的效果。方法:经眼底荧光造影(fundus fluorescein angiography,FFA)和光学相关断层扫描(optic coherence tomagraphy,OCT)检查确诊为视网膜中央静脉阻塞伴黄斑囊样水肿的患者137例137眼,进行格栅样光凝。术后1wk;1,3mo复查视力、FFA及OCT。结果:术后1mo检查结果:视力提高者为119眼(86.9%),不变者18眼(13.1%);术后3mo检查结果:视力提高者为124眼(90.5%),不变者13眼(9.5%)。治疗后1mo及3mo视力与治疗前比较均有显著性差异。结论:格栅样光凝治疗中央静脉阻塞致黄斑囊样水肿效果肯定,但必须要有足够量的有效的光凝斑,并要根据眼底状况决定格栅样光凝的方式。

AIM：To analyze curative effect of grid photo-coagulation in treatment of macular vesicular edema caused by central retinal vein occlusion.METHODS：One hundred thirty-seven patients （137 eyes） with macular vesicular edema caused by central retinal vein occlusion were detected with visual acuity,optical coherence tomography（OCT） and fundus fluorescein angiography（FFA） 1 week, 1 month, 3 months after grid photo-coagulation. RESULTS：Totally 119 eyes（86.9%） showed visual improvement and 18 eyes（13.1%）showed visual stability 1 month after treatment; 124 eyes（90.5%） showed visual improvement and 13 eyes（9.5%）showed visual stability 3 months after treatment. The visual acuity improved significantly 1 month and 3 months after treatment. CONCLUSION： The curative effect of grid photo-coagulation in treatment of macular vesicular edema caused by central retinal vein occlusion is affirmative. It is necessary that there should be sufficient effective photo-coagulation spot and correct photo-coagulation modality based on fundus condition in treatment
