激光治疗白内障超声乳化术后糖尿病视网膜病变时机探讨

目的观察白内障超声乳化术后糖尿病视网膜病变（diabetic retinopathy,DR）激光光凝治疗的效果和时机。方法对45例72眼白内障超声乳化术后DR患者进行了氩激光治疗,分析不同治疗时机的疗效。结果白内障术后2-3周内行激光光凝治疗,糖尿病视网膜病变稳定,黄斑水肿消退或减轻为76.9%,不变为23.1%;视力提高或不变为80.8%,视力下降为19.2%。白内障术后1-3个月行激光光凝治疗,20眼中有16眼糖尿病视网膜病变加重,黄斑水肿消退或减轻占70.0%,不变为30.0%;视力提高或不变为75.0%,视力下降为25.0%,视力下降与黄斑水肿程度密切相关。结论白内障术后1个月内DR患者尽早进行激光光凝,对控制或延缓糖尿病视网膜病变的发展极为重要。

Laser treatment of diabetic retinopathy after phacoemulsification

Objective To study the effect of laser treatment on diabetic retinopathy（DR） after phacoemulsification and its mechanism. Methods Seventy-two eyes with diabetic retinopathy were treated with argon laser in 45 patients. The effect of laser treatment on diabetic retinopathy was observed. Results Two-three weeks after treatment with laser, diabetic retinopathy became stable, macular edema was disappeared or reduced in 76.9% of the patients, remained unchanged in 23.1% of the patients, visual acuity increased in 80.8% of the patients and decreased in 19.2% of the patients. One-three months after treatment with laser, developed diabetic retinopathy was observed in 16 eyes, macular edema was disappeared or mitigated 70.0% of the patients, remained unchanged 30.0% of the patients, visual acuity was increased in 75.0% of the patients and decreased in 25.0% of the patients. Conclusion Laser photocoagulation should be performed for diabetic retinopathy one month after phacoemulsification in order to control or delay the advance of diabetic retinopathy.
