摘要

回顧過去五年內，在榮民總醫院接受氬氣雷射汎網膜光凝固治療的650名增殖性糖尿病網膜症的病歷，採用資料完整的432名（621眼），經過3至44個月，平均12.5個月的追踪，總共有51眼(8.2%)發生「急性視力減退」，亦即雷射治療後一個月內視力減退三行或以上。主要的原因是黃斑部水腫增加及玻璃體出血、中心窩脂質滲出物及牽引性網膜剝離等。由黃斑部水腫增加引起的視力減退有一半的人在3個月內自然復原。本文將討論雷射治療的方法或密集度與急性視力減退的關連性，及事先存在之玻璃體出血對汛網膜光凝固治療所造成的危險性。

We reviewed 621 eyes with proliferative diabetic retinopathy that were treated with argon laser panretinal photocoagulation in our hospital between 1980 and 1984. The mean follow up period was 12.5 months. Acute visual loss, defined here as vision decreased three lines or more within one month after each session of laser treatment, occured in 51 eyes (8.2%). The most common causes were increased macular edema (3.4%) and vitreous hemorrhage (2.7%). About one third of those cases with decreased vision recovered spontaneously within three months, especially in cases caused by increased macular edema. The relationship between differences in density of laser treatment arid the occurence of acute visual loss, and how preexistent vitreous hemorrhages acted as a predisposing high risk factor were discussed.
