Abstract
Various nonglaucomatous disorders may produce optic disc cupping and visual field disturbances that resemble the clinical profile of normal tension glaucoma (NTG), and it is important that clinicians recognize them. These disorders include hereditary optic neuropathy, antecedent optic nerve infarction, trauma, syphilis, demyelinating optic neuritis, fusiform enlargement of the intracranial carotid artery, and intraorbital and intracranial mass lesions
