Optic neuropathies (ON) occur in a variety of clinical presentations depending on their pattern of occurrence, their topography and the amount of functional visual impairment. Management of an ON requires a sequence of steps: confirm its existence (positive diagnosis): the diagnosis of ON is usually clinical and must be considered in the case of decreased visual acuity, change in color vision, visual field defect, relative afferent pupillary defect (RAPD), and absence of macular pathology; rule out differential diagnoses: determine the cause; etiologic diagnosis is sometimes complex and takes shape from clinical and paraclinical building blocks. The etiology may be vascular, inflammatory or demyelinating, infectious, toxic, vitamin-deficient, compressive (neoplastic or non-neoplastic), hereditary, congenital, traumatic or even pressure-related (glaucoma or advanced intracranial hypertension). Cerebral and orbital imaging with fine cuts of the optic nerves is often a mandatory examination, which is sometimes useful to repeat; identify therapeutic emergencies.
