Diabetic
Retinopathy-Proliferative
Neovascularization
(growth of new blood vessels), usually out of the retina and along the surface of the vitreous or into the vitreous cavity,
leading to the formation of scar tissue on the surface of the retina (which can cause retinal tears and detachment) and leaking
of blood by the new fragile vessels into the eye (vitreous hemorrhage), all capable of causing severe vision loss or blindness.
