Neovascular glaucoma

Neovascular glaucoma (NVG) is the presence of new blood vessels on the iris in the affected eye. It wasn't until the 20th century that knowledge about NVG was built on sound anatomy. In 1906, Coats described the histological findings of central retinal vein occlusion and new blood vessels on the iris in the affected eye. In 1928, Salus described similar new blood vessels on the iris in the eyes of diabetic patients. In the early twentieth century, after the introduction of gonioscopy in clinical applications, Kurz believed that the contraction of connective tissue was responsible for the closure of the adhesive angle. Given that the cause of this glaucoma is neovascularization rather than intraocular hemorrhage, Weiss equaled the name of neovascular glaucoma in 1963.
