Postoperative onset or aggravation of cystoid macular oedema (CMO) in diabetic patients after extracapsular cataract extraction (ECCE) with intraocular lens (IOL) implantation is a frequent problem. At present little is known about the occurrence and prognosis of this complication in diabetics with no clinically detectable diabetic retinopathy (DR). Twenty five diabetic eyes (24 subjects) without DR and 45 normal eyes (44 subjects) were studied before surgery and 30, 90, 180, 360 days after ECCE and posterior chamber IOL implantation. Fluorescein angiography was performed at each examination. The frequency of angiographic CMO in the two groups was comparable 30 days after surgery but was significantly higher in diabetic eyes at 90, 180, and 360 days. This finding is probably related to an impairment of the blood-retinal barrier in diabetics. Final visual acuity, however, was similar in the two groups.
糖尿病患者在行囊外白内障摘除术（ECCE）并植入人工晶状体（IOL）后发生囊样黄斑水肿（CMO）或使原有水肿加重是一个常见问题。目前，对于无临床可检测糖尿病视网膜病变（DR）的糖尿病患者发生该并发症的情况及预后了解甚少。对25只无DR的糖尿病眼（24名受试者）和45只正常眼（44名受试者）在手术前以及ECCE和后房型IOL植入术后30天、90天、180天、360天进行了研究。每次检查均进行荧光素血管造影。术后30天时，两组血管造影显示CMO的频率相当，但在90天、180天和360天时糖尿病眼中该频率显著更高。这一发现可能与糖尿病患者血视网膜屏障受损有关。然而，两组的最终视力相似。
