Proliferative retinopathy in a child with congenital cyanotic heart disease.

In congenital cyanotic heart disease, oxygenated and deoxygenated blood mixes, and oxygen saturation of the arterial blood is not maintained. As a result, an ischemic environment prevails in the entire body. While various ocular findings have been described in patients with cyanotic heart disease, proliferative retinopathy has not been previously noted. We report a child with congenital cyanotic heart disease and multiple fibrovascular fronds over the fundus consistent with proliferative retinopathy.
