Retinal and pregnancy outcomes in the presence of diabetic proliferative retinopathy.

The objective of this study was to examine the retinal and pregnancy outcomes of pregnancies complicated by advanced diabetic retinopathy. Twenty pregnancies complicated by advanced diabetic retinopathy were included in this retrospective study. The data were analyzed to determine trends in perinatal outcome and to document the ophthalmologic performance. Ophthalmologic management included frequent funduscopic examinations by ophthalmologists of the Yale Retina Center. Among the 20 pregnancies, spontaneous abortion occurred in 2 (10%) and stillbirth in 1 (5%); the remaining 17 (85%) pregnancies culminated in live births at a mean gestational age of 36 weeks (+/- 2.3 SD), with a mean birth weight of 2,620 g (+/- 834 SD). The perinatal survival rate was 94%. Photocoagulation therapy was necessary prior to pregnancy in 45%, during pregnancy in 60% and postpartum in 65%. No pregnancies were terminated because of progressive visual changes that did not respond to photocoagulation therapy. Retinal status should not preclude pregnancy since contemporary methods of management can result in satisfactory retinal and pregnancy outcomes even in the presence of advanced diabetic microvascular disease.
