Does the severity of diabetic retinopathy predict pregnancy outcome?

The authors sought to determine whether the severity of diabetic retinopathy is a predictor of subsequent pregnancy outcome. One hundred and seventy-nine pregnant diabetic women were evaluated in their first trimester of pregnancy. Stereoscopic color photographs of the ocular fundus were taken and graded by the Fundus Photography Reading Center. Thirty-nine women had no retinopathy, while 28 had proliferative retinopathy in the worse eye. The women's history and hospital delivery room charts were reviewed with regard to pregnancy outcome. Thirty-three pregnancies terminated with an adverse outcome. A logistic regression analysis was used to evaluate significant predictors of pregnancy outcome. Of maternal age, duration of diabetes, glycosylated hemoglobin, proteinuria, cigarette smoking status, and severity of diabetic retinopathy, only the last variable significantly predicted an adverse outcome. These data suggest that the severity of retinopathy should be considered when counseling a pregnant diabetic woman.
