    Normal-tension glaucoma (NTG) is an optic neuropathy of unknown etiology characterized by optic disc excavation, retinal nerve fiber layer loss, and visual field defects similar to those seen in other forms of glaucomatous optic neuropathy. Patients with glaucomalike optic nerve and visual field changes yet normal intraocular pressure are numerous and require treatment to preserve vision.
