根据随机对照原则,对26眼(治疗组14眼)继发于视网膜静脉阻塞后的黄斑囊样水肿进行了前瞻性高压氧治疗。治疗组在治疗前后平均视力提高3.7行(2～6行),有效率100％,对照组提高0.18行(1～2行),有效率18％,两组比较有显著性差异。随访3～6个月,治疗组视力稳定或继续上升。但荧光造影显示治疗前后黄斑囊样水肿的变化无明显差异。认为高压氧治疗本病,适应症宽,副反应少,增加缺血视网膜的氧供,促使血管收缩,减少渗漏,是一种增进视力,缩短病程的较好的治疗方法。
According to the principle of randomized control, prospective hyperbaric oxygen therapy was administered to 26 eyes (14 eyes in the treatment group) secondary to cystoid macular edema following retinal vein occlusion. The mean visual acuity of the treatment group increased by 3.7 lines (2-6 lines) before and after treatment, the effective rate was 100%, while the control group increased by 0.18 line (1 ~ 2 lines) and the effective rate was 18%. There was significant difference between the two groups. Followed up for 3 to 6 months, the treatment group, visual acuity or continue to rise. However, fluorescence imaging showed cystoid macular edema changes before and after treatment no significant difference. Hyperbaric oxygen therapy that the disease, indications wide, less side effects, increased oxygen supply of ischemic retina, to promote vasoconstriction and reduce leakage, is a better vision, shorten the course of the better treatment.
