Vascular tufts in retrolental fibroplasia

Three cases of retrolental fibroplasia with vascular tufts at different locations are described. They probably represent mesenchymal proliferation in response to severe hypoxia. The tufts are reddish-pink in color and angiographically do not leak fluorescein. When present posterior to the equator they suggest an immature retinal circulation and the visual prognosis is poor.
