Does pregnancy accelerate the rate of progression of diabetic retinopathy?

Pregnancy may be associated with a number of ocular changes, including the development of new ocular conditions or modifications of existing conditions. The most common ocular condition modified by pregnancy is diabetic retinopathy. Pregnancy is associated with an increased risk of development and progression of diabetic retinopathy. The factors associated with its progression include the pregnant state itself, duration of diabetes, amount of retinopathy at conception, blood glucose control, and the presence of coexisting vascular disease. Although the rate of regression of diabetic retinopathy at the end of pregnancy or the postpartum period is high, careful monitoring of these patients is necessary to optimize both the vision and pregnancy outcomes.
