[Progression of diabetic retinopathy during pregnancy].

Diabetic retinopathy should be carefully monitored during certain risk situations. Indeed, diabetic retinopathy in pregnant type 1 diabetic patients can rapidly progress and threaten vision, as in other situations such as puberty, glycemic equilibration, or ocular surgery. During pregnancy, five major risk factors for progression have been identified: pregnancy itself, diabetic retinopathy grade at baseline, duration of diabetes, important glycated hemoglobin reduction, and high blood pressure. These factors must be taken into account when planning pregnancy in diabetic patients and during the follow-up of their diabetic retinopathy. Diabetic women should be counseled about the risks of progression of their disease before planning pregnancy. Careful eye examination before and during the first trimester should be done in these patients, in order to detect severe non-proliferative diabetic retinopathy and/or high-risk diabetic retinopathy and perform rapid laser treatment if needed. Follow-up visit frequency should be adapted to the severity of the diabetic retinopathy. Very few authors have studied diabetic macular edema during pregnancy. This complication can spontaneously regress postpartum and should not be treated too rapidly.
