目的:探讨合并糖尿病眼底病变患者白内障术后与正常眼底的患者白内障术后的黄斑水肿和视力恢复情况。 方法:选取63例63眼白内障患者，其中33例伴有轻至中度糖尿病眼底改变，为糖尿病组；另外30例正常眼底为对照组。相同的术式、手术医生及术后处理。于术前、术后1，6wk及6mo检查视力及眼底情况，于术前、术后6wk行荧光素眼底血管造影检查，观察两组术后黄斑水肿及视力恢复情况。 结果：糖尿病患者32例及对照组29例患者完成检查并随访。术后6wk，糖尿病组有24例（75%）出现眼底渗漏，而对照组只有6例（21%）；糖尿病组有5例（16%）出现临床型黄斑囊样水肿（CME），对照组有2例（7%）出现临床型CME；术后6mo，两组视力水平差异无显著性，黄斑水肿恢复。 结论：白内障术后不管是对正常眼底还是对伴轻中度糖尿病视网膜病变都可发生CME，但视力恢复无明显差异，发生CME予随诊，一般不需处理，多能自行恢复。

AIM:To compare the macular edema (ME) and visual outcome after cataract surgery in eyes with diabetic retinopathy with normal eyes. METHODS:Thirty-three patients with type-2 diabetes and 30 controls were enrolled. Visual acuity and fundus were examined preoperation, and at postoperative 7 days, 6 weeks and 6 months. Fluorescein fundus angiography(FFA) was performed preoperation and at postoperative 6 weeks. Postoperative ME and visual recovery in two groups were observed. RESULTS:There was no statistically significant difference in visual acuity between preoperative and postoperative 7 days or 6 months, but at 6 weeks there was a significant difference with lower VA in the diabetic group. 7% of control and 16% of diabetic eyes developed clinical cystoid macular edema (CME). Incidence of fluorescein angiography (FA) leakage was 21% in control and 75% in diabetic eyes. There was no significant difference in visual acuity at postoperative 6 months between two groups, and ME recovered. CONCLUSION:The final visual outcome in eyes with mild to moderate retinopathy is as good as in normal eyes, but an increased frequency of macular changes may protract recovery of full vision. For this kind of CME, generally no treatment is needed, they can recover by themselves.
