Optic neuritis: differential diagnosis.

Optic neuritis can be mimicked by other optic neuropathies and by anterior segment, choroidal or retinal diseases. Retinal diseases may cause central visual loss when they involve the macular or peripapillary area. Central serous retinopathy, hereditary retinal diseases, white dots syndromes and autoimmune retinopathies may present a clinical picture similar to that of optic neuritis. Complete neuro-ophthalmological examination must be performed to differentiate optic nerve damage from other ocular structures involvement. As in optic neuritis, optic disc and macula appearance may be completely normal in several retinal diseases. Fluorescein angiography and electrophysiological testing are relevant for the differential diagnosis in many challenging cases.

Non-demyelinating optic neuropathy: clinical entities.

Alternative causes of optic neuritis (ON), other than primary demyelination or non-demyelinating optic neuropathies which can mimic acute ON, should be rigorously considered if a patient with presumed ON does not follow the typical clinical course or has a normally appearing brain on magnetic resonance imaging. A thorough differential diagnosis includes viral and bacterial optic neuropathies, ischemic optic neuropathies, Devic's neuromyelitis optica, compressive or infiltrative optic neuropathies, Leber's hereditary optic neuropathy and toxic and deficiency optic neuropathies. All patients should undergo a complete neuroophthalmological examination to help exclude other diseases mimicking ON. Atypical clinical cases of optic neuropathy require further specific laboratory, neurophysiological and imaging tests to make a correct and early diagnosis.
