目的：评估视网膜中央动阻塞后视力的可恢复性。方法：对发病后视力为无光感、光感、手动和指数的５６例６０只眼治疗前后视力变化和视网膜循环时间进行了观察。结果：６０只眼中视力为无光感者１８只眼，丧失视力的时间中位数为４５天；光感至指数者４２只眼，丧失视力的时间中位数为５天。在经过平均２７．８天的观察后，无光感的１８只眼中有１２只眼的视力增进至光感与０．０３之间；光感至指数的４２只眼中有４０只眼的视力增进至手动至０．７之间。３５只眼治疗前后眼底荧光血管造影资料统计表明，１０只无光感眼中视网膜循环时间平均缩短（１．５±１．１）秒（Ｐ＜０．０１）；光感至指数的２５只眼平均缩短（１．３±１．０）秒（Ｐ＜０．００１）。结论：视网膜中央动脉阻塞患者已丧失的视力具有一定的可恢复性。
Objective: To assess the visual acuity recoverability after central retinal artery occlusion. Methods: Visual acuity changes and retinal circulation time were observed in 56 eyes (56 eyes) with no visual acuity, sensation of light, manualness and exponential function. Results: In 60 eyes, there were 18 eyes with no light perception, the median time of vision loss was 45 days, 42 eyes with light perception index and 5 eyes with loss of vision. After an average of 27.8 days of observation, 12 eyes of 12 eyes without light perception improved their light perception to between 0.03 and 0.03; 40 eyes of 42 eyes with light perception showed an increase in eyesight To manual to between 0.7. The fundus fluorescein angiography data of 35 eyes before and after treatment showed that the retinal circulation time was shortened (1.5 ± 1.1) seconds on average in 10 eyes (P <0.01) and 25 eyes Shortens (1.3 ± 1.0) seconds on average (P <0.001). Conclusions: Vision loss in patients with central retinal artery occlusion has some recoverability.
