摘要
研究后巩膜加固术对眼球发育、眼底形态和眼底血液循环的影响。方法 对19只15～20日龄的大白兔一眼行后巩膜加固术,另一眼做自身对照,对比其眼轴长度、角膜直径和眼底形态。术后3个月,采用血管荧光造影方法与正常对照组进行对比观察。结果 实验组与自身对照组比较,眼轴长度、角膜直径、眼底形态均无差异。荧光造影,实验组与正常对照组比较,视网膜动脉充盈快。结论 后巩膜加固术对眼球发育、眼底形态和脉络膜循环无明显影响。此手术可改善兔的视网膜循环。
The study was designed to observe the effects of scleral reinforcement (SR) on eyeball development, fundus and blood circulation. Methods One eye in each of 19 white rabbits was operated on 15 ~ 20 days after birth, another eye was used as self control. The length of axis, cornea diameter and fundus of the two eyes in each rabbit were compared three months after the surgery with fundus fluorescein angiography. Results Compared with those in self control group , the length of axis, cornea diameter and fundus remained unchanged. Retina artery filling that underwent SR was faster than that of the normal controls. There was no difference in other index between the two groups. Conclusions Scleral reinforcement didn't affect eyeball development, fundus and choroidal circulation. This operation could improve the retinal circulation.
