Neovascularization of the disc (NVD) associated with extensive fibrovascular proliferation.

Opaque fibrovascular proliferation tissue often appears on the internal limiting membrane (adjacent to the new vessels) and becomes adherent to the posterior vitreous. Contraction of this fibrovascular tissue may lead to: Distortion or dragging of the macula Mild to extensive tractional retinal detachment Avulsion of retinal vessels Preretinal and/or vitreous hemorrhages
