| Abstract |
|
To assess the effect of cataract surgery on diabetic retinopathy(DR)and to identify the risk factors for the postoperative progression of DR, we reviewed the medical records of 214 diabetic patients who had undergone cataract surgery from August 1997 to November 1998.Out of total 274 eyes, 58 eyes(19.6%)showed progression of DR by one or more grades in ETDRS classification after cataract surgery. One hundred fifty eyes(56.9%) achieved postoperative visual acuity of 0.5 or better and 214 eyes(78.1%) showed an improvement in visual acuity by two lines or more. Compared with non-progression group, progression group showed statistically significant decrease in postoperative visual acuity. Preoperative severity of DR, glucose control with insulin, and the presence of postoperative macular edema within 3 months were identified as significant risk factors to progress DR. Operative method, intraocular lens position or intraoperative posterior capsular tear did not seem to contribute to the progression of DR. In conclusion, the severity of DR and the status of glucose control at the time of cataract surgery were highly correlated with the postoperative progression of DR. |
