“Dual‐pressure theory” in pathogenesis of glaucomatous optic neuropathy from the Beijing intracranial and intraocular pressure study

Eye &ENT Research, Volume 1, Issue 1, Page 11-19, June 2024.
Abstract The mechanical theory of glaucoma indicates that high intraocular pressure (IOP) leads to glaucomatous optic nerve damage. However, nearly half of primary open‐angle glaucoma patients with normal intraocular pressure also exhibit progression of what appears to be glaucomatous optic nerve damage. Our earlier prospective study identified for the

A national survey of diagnostic tests reported by UK community optometrists for the detection of chronic open angle glaucoma [PDF]

, 2011
Purpose:  In the UK, the majority of cases of chronic open angle glaucoma are detected by community optometrists following a routine sight test. However, there is potential for variability in case finding strategies used.
