Seventy-three diabetes with retinopathy, in whom one eye was treated by photocoagulation, and the other was left untreated, were followed-up for 9 to 11 years. Visual acuity, visual field, dark-adaptation curves, and intraocular pressure were recorded; biomicroscopy and photography of the fundus were carried out. Severe visual loss (<0.1) was noted in 4% of the treated and in 25% of the untreated eyes. Minor, subjectively unnoticed, scotomas were found at visual-field examination in 18 of 40 treated eyes. Dark-adaptation curves showed abnormal values both in the treated and in the untreated eyes, without any recordable difference. No contra-indicating long-term complications of the photocoagulation treatment could be demonstrated.
73例患有视网膜病变的糖尿病患者，一只眼睛接受了光凝治疗，另一只眼睛未接受治疗，随访9至11年。记录视力、视野、暗适应曲线和眼压；进行生物显微镜检查和眼底摄影。治疗眼中有4%出现严重视力丧失（<0.1），未治疗眼中有25%出现严重视力丧失。在40只接受治疗的眼中，有18只在视野检查中发现了轻微的、主观上未被注意到的暗点。暗适应曲线在治疗眼和未治疗眼中均显示异常值，无任何可记录的差异。未发现光凝治疗的禁忌性长期并发症。
