Optimal documentation of retinal lesions by panorama fundus photographs is required for evaluation of the course of diabetic retinopathy (DR). The data are prepared for automatic storage and computation. The natural course of DR is occasionally characterized by remarkable spontaneous remissions. Therefore, unilateral treatment is needed to evaluate the efficacy of photocoagulation. The following preliminary results on 215 patients treated unilaterally with Xenon photocoagulation, and followed up for 6 months to 6 years, were statistically significant: marked decrease of intra- and epiretinal vessel new formations, prophylaxis of retinal neovascularization and vitreous hemorrhages, preservation of the macula and retention of visual acuity in diabetics below 60 years of age. The unpredictable rate of progression of DR in individual cases is responsible for occasional failures of photocoagulation.
为评估糖尿病视网膜病变（DR）的病程，需要通过全景眼底照片对视网膜病变进行最佳记录。数据准备用于自动存储和计算。DR的自然病程偶尔会有显著的自发缓解特征。因此，需要进行单侧治疗以评估光凝治疗的疗效。以下是对215例接受氙光凝单侧治疗并随访6个月至6年的患者的初步结果，具有统计学意义：视网膜内和视网膜前血管新形成明显减少，预防视网膜新生血管形成和玻璃体出血，60岁以下糖尿病患者黄斑的保留和视力的维持。个别病例中DR不可预测的进展速度导致光凝治疗偶尔失败。
