对158例视网膜脱离病人手术前后的视功能进行观察：术后有改善的56．96％，脱盲的（＞0．05）占74．8％，脱残的（＞0．3）占27．8％。视野2～4周变化较大，多数半年后视野扩大10°以上，40％的病人视野可达18～20DB，扩大20°～30°，术后视力在0．1以下的色觉消失的占84％，＞0．5的色觉基本正常，ERG术前b波振幅高的术后机功能恢复较好，视功能术后2周内变化较大，一般3年左右稳定。视野、色觉一般与中心视力呈正比。荧光血管造影显示黄斑有病变或脱离的术后视功能恢复得慢而差。 The visual function of 158 patients with retinal detachment before and after operation was observed: 56.96% improved after operation, 74.8% got rid of blindness (> 0.05), and 27 disabled (> 0.3). 8%. Visual field 2 to 4 weeks vary greatly, most of the six months after the field of vision to expand more than 10 °, 40% of patients with field of vision up to 18 ~ 20DB, expand 20 ° ~ 30 °, postoperative visual acuity less than 0.1 accounted for 84% 84 %,> 0.5 color vision was normal, ERG preoperative b wave amplitude high postoperative recovery of better postoperative function, visual function within 2 weeks after the larger changes, usually about 3 years stable. Vision, color vision is generally proportional to central vision. Fluorescein angiography showed that macular lesions or detachment of postoperative visual function recovered slowly and poorly.
