WebThe pathogenesis of glaucoma remains an active area of ophthalmic research. Both mechanical and vascular factors may contribute to glaucomatous optic neuropathy. In this article, Dr. Weinreb and colleagues discuss the role of vascular dysregulation, specifically low ocular perfusion pressure, in both the development and progression of glaucoma. WebAccording to the mechanical theory, increased intraocular pressure (IOP) causes stretching of the laminar beams and damage to retinal ganglion cell axons. The vascular theory of glaucoma considers GON as a consequence of insufficient blood supply due to either increased IOP or other risk factors reducing ocular blood flow (OBF).
