Recurrent vitreous hemorrhage associated with proliferative retinopathy can occur in eyes that do not satisfactorily respond to argon laser pantretinal photocoagulation. To evaluate the effect of relatively low-risk surgical intervention, we performed peripheral retinal cryopexy on 24 eyes of 23 diabetic patients with proliferative diabetic retinopathy and vitreous hemorrhage. In most cases, cryopexy followed complete or nearly complete panretinal photocoagulation which did not prevent subsequent vitreous hemorrhage. Existing vitreous hemorrhage cleared postoperatively in 23 of 24 eyes. The best corrected visual acuity improved in 15 eyes, remained unchanged in five, and worsened in four. Four postoperative anterior segment complications resolved completely within a short time. One patient, a 68-year-old woman who had had diabetes for 18 years, postoperatively had a macular hole in one eye and macular edema with tractional retinal detachment in the other.
与增殖性视网膜病变相关的复发性玻璃体出血可发生在对氩激光全视网膜光凝反应不佳的眼睛中。为了评估相对低风险手术干预的效果，我们对23例患有增殖性糖尿病视网膜病变和玻璃体出血的糖尿病患者的24只眼睛进行了周边视网膜冷冻疗法。在大多数情况下，冷冻疗法是在全视网膜光凝完全或几乎完全完成后进行的，但这并未预防随后的玻璃体出血。24只眼中的23只眼术后现有玻璃体出血清除。15只眼的最佳矫正视力提高，5只眼保持不变，4只眼恶化。4例术后前段并发症在短时间内完全消退。一名68岁、患糖尿病18年的女性患者，术后一只眼睛出现黄斑裂孔，另一只眼睛出现黄斑水肿并伴有牵引性视网膜脱离。
