Early vitrectomy was carried out in 22 eyes with proliferative diabetic retinopathy and evidence of partial vitreous detachment in 17 patients with insulin-dependent diabetes. All the eyes had undergone panretinal laser photocoagulation, and all had a visual acuity of 6/12 or better, but 13 had had a vitreous hemorrhage. After a mean follow-up period of 29 months 19 of the eyes had retained the same visual acuity, 18 had been free of renewed vitreous hemorrhage for 6 months, there had been no macular retinal detachments and all the anterior segments were normal. The three instances of persistent visual loss were due to recurrent vitreous hemorrhage.
对17例胰岛素依赖型糖尿病伴增殖性糖尿病视网膜病变且有部分玻璃体脱离迹象的患者的22只眼实施了早期玻璃体切除术。所有患眼均接受了全视网膜激光光凝治疗，且视力均在6/12或更好，但其中13只眼曾发生过玻璃体出血。平均随访29个月后，19只眼视力保持不变，18只眼6个月内未再次发生玻璃体出血，未出现黄斑视网膜脱离，且所有眼前节均正常。3例持续性视力丧失是由复发性玻璃体出血所致。
