1 Slide in 5 Minutes: Neovascular Glaucoma (Malik Y. Kahook, MD)

Neovascular Glaucoma (NVG) presents as a secondary open-angle or secondary closed-angle glaucoma, depending on the extent of fibrovascularization and synechiae formation in the drainage angle. The abnormal vessels form in response to ischemia of the retina and are composed of highly permeable thin walls (lacking a muscular layer or normal adventitia) with absence of tight intercellular junctions. Aqueous outflow is compromised by the fibrovascularization with/without synechiae formation (which form when the fibrovascular membranes, composed of fibroblasts with smooth muscle differentiation, contract over time) leading to increased intraocular pressure (IOP). www.keogt.com www.sidratreefoundation.com Expanded transcript: https://www.keogt.com/Neovascular_Gla... #Glaucoma #Eye #Surgery #GDD #AhmedValve #Ophthalmology #Anti-VEGF #Laser #Medications
