Overview
A subtype of primary open-angle glaucoma characterised by progressive glaucomatous optic neuropathy with corresponding visual-field loss and an open anterior chamber angle, despite untreated measured IOP remaining within the statistically normal range. Normal measured IOP alone does not establish NTG: reproducible structural-functional damage, progression where available, open-angle assessment and exclusion of non-glaucomatous optic neuropathy are required.
