Neovascularization of the Iris (Video)

This video shows new, abnormal blood vessels growing on the surface of the iris. This NVI (neovascularization of the iris) is usually seen with bad diabetic retinopathy or central retinal vein occlusions. Any ischemic state in the retina can lead to VEGF upregulation … thus promoting new vessel growth.

Iris vessels are an ominous sign, however, as they can bleed and the vessels can clog up the trabecular meshwork and cause a dangerous neovascular glaucoma that is difficult to treat.
