If it develops in early gestation first trimester and there is no response to treatment pregnancy termination might have to be offered as an alternative. 4 Vaginal delivery may be allowed for those patients with background or successfully treated proliferative retinopathy. The optimal route of delivery for those patients with active proliferative retinopathy has not been determined since in non-pregnant patients vitreous hemorrhages may occur even during periods of inactivity. Vitreous hemorrhages have been observed during both cesarean sections and vaginal deliveries but there is concern that they may occur more readily during the active expulsion phase of vaginal birth.

Better outcomes are consistently obtained in centers offering a multidisciplinary team approach. Perinatal complications may include congenital anomalies fetal growth restriction fetal death stillbirth and preterm delivery with its associated neonatal morbidity from prematurity. Maternal complications include worsening of renal function during or after pregnancy anemia superimposed pre-eclampsia or eclampsia and worsening of other diabetic complications frequently coexisting with nephropathy mainly retinopathy see previous section .
