Iris neovascularization and fibrovascular membrane

Iris neovascularization is not a primary disease of the iris, but secondary to many eye diseases and some systemic diseases. Because it can develop into or merge with the formation of fibrous vascular membranes, resulting in severe neovascular glaucoma due to the closure of the iris corneal corners, the intraocular pressure is often difficult to control, and eventually the blindness of the affected eye or even the removal of the eyeball due to severe eye pain. Therefore, it is important to detect and deal with it early. After Bader described the iris neovascularization in 1868, many authors successively reported the iris neovascularization associated with diabetes, central retinal vein occlusion and other patients. Due to the advancement of examination technology, especially the clinical application of fluorescent angiography, the discovery of iris neovascularization is increasing.
