氪黄激光治疗糖尿病性视网膜病变黄斑水肿

目的：评价氪黄激光治疗糖尿病性视网膜病变黄斑水肿的临床疗效。方法：用氪黄激光治疗糖尿病性视网膜病变黄斑水肿共34例（48眼），氪黄激光波长568nm，对黄斑区局部水肿采用局部光凝，弥漫性水肿采用C形格栅状光凝，光凝距黄斑中心小凹300um，避开视盘黄斑束，功率60～20mw，光斑直径100um，曝光时间0.1s，光凝68～189点，光斑反应I-Ⅱ级。术后平均随访10个月。结果：术后视力提高者33眼（68.8%），不变者13眼（27.1%），下降者2眼（4.2%）。光凝后黄斑水肿完全消退者15眼（31.3%），部分消退者28眼（58.3%），不变者5眼（10.4%）。无明显并发症。结论：氪黄激光治疗糖尿病性视网膜病变黄斑水肿安全、有效。

Krypton yellow laser photocoagulation for macular edema of diabetic retinopathy

Objective: To evaluate the clinical effects of krypton yellow laser photocoagulation for macular edema in diabetic retinopathy. Methods: 48 eyes (34 cases) of diabetic retinopathy with macular edema were treated with local or grid macular krypton yellow photocoagulation. The course of followed-up was 10 months. Results: The visual acuities were 0.17(0.19 before treatment and 0.37(0.28 after treatment (P<0. 01), were increased in 68.8% of the subject eyes, stable in 27.l and decreased in 4.2%. Macular edema disappeared completely in 31.3% of the patients, disappeared partially in 58.3% and stable in 10.4%. Conclusions: Krypton yellow laser photocoagulation seems prominently effective and safe for the macular edema of diabetic retinopathy.
