[PCL implantation in diabetic patients--examination of CME and maculopathy].
We performed posterior chamber lens (PCL) implantation in 287 eyes of 207 diabetic patients, and evaluated postoperative cystoid macular edema (CME) and diabetic maculopathy. The rate of CME was 9.3% and its average period after surgery was 3.6 months. The incidence of diabetic maculopathy was 3.4% and it appeared 8.8 months after operation on average. In both the CME group and diabetic maculopathy group, the duration of diabetes, HbAlc value, the grade of diabetic retinopathy and the conditions of general complications were significantly higher than in those without CME and maculopathy. Only in the diabetic maculopathy group were the pre- and postoperative dilated pupillary diameter significantly smaller. CME patients were treated with oral or subconjunctival injection of corticosteroids, when diabetes was controlled and they had no or mild retinopathy, and good visual acuity was recovered (0.98 on average). The other patients with CME were treated with laser photocoagulation, and they regained a visual acuity of 0.50 on average. All patients with maculopathy were treated with laser photocoagulation, but they regained a visual acuity of 0.36 on average. The postoperative protein concentration in the anterior chamber was significantly higher in the CME group than in the non-CME group at one day and also at three months after operation.
