Title

Chronic Optic disc cupping. Is it Glaucoma? Or Not?

Purpose	Pathological optic disc cupping associated with normal intraocular pressure (IOP) is most often caused by open-angle glaucoma but may represent a diagnostic challenge when caused by many less-common neuro-ophthalmic conditions.
Methods	This article reviews the clinical differentiation between physiologic cupping and pathologic cupping, and the subclassification of eyes with glaucomatous and nonglaucomatous optic disc cupping.
Results	Up to 10-20% of patients may be misdiagnosed and treated for glaucoma due to misinterpretation of the optic-disc cupping.
Conclusion	A careful interpretation of the history, optic disc characteristics and visual fields are quintessential to the diagnosis of glaucomatous versus non-glaucomatous optic disc cupping, avoiding misinterpretation or inappropriate neuroimaging examinations.
