Familial exudative vitreoretinopathy (FEV) is an autosomal dominant disorder. It is characterized clinically by the presence of avascular areas and proliferative lesions in the temporal peripheral retina, with retractive exudative retinal detachment seen in the neonatal period. The fundus changes in FEV are the same as those seen in retinopathy of prematurity. Differential diagnosis: retinopathy of prematurity: occurs in low birth weight preterm infants, often with a history of heavy oxygenation. FEV often occurs in term infants without a history of oxygenation.
