The exact cause of primary open angle glaucoma is still unknown. Intraocular pressure is a major factor but it is impossible to explain the whole mechanism of glaucomatous optic nerve damage with only increased intraocular pressure. Other factors play important roles in the development of glaucoma. With this point of view, vascular factors have been implicated in the pathogenesis of glaucoma.
