{{Short description|Inflammation of the optic nerve head}}
Papillitis is the term for a specific type of optic neuritis. If ocular inflammation is restricted to the optic nerve head the condition is called papillitis (or intraocular [[optic neuritis]]) and if it is located in the orbital portion of the nerve it is called retrobulbar optic neuritis (or orbital optic neuritis).[http://medical-dictionary.thefreedictionary.com/papillitis Medical Dictionary]

[[Papilledema]], a bulging of the optic disc, is a consequence of elevated intracranial pressure. There are some important differences between papillitis and papilledema, notably, that papillitis is more often associated with pain on moving the globe, and sensitivity to light pressure on the globe. Papillitis is often an early sign of multiple sclerosis. (Pretest Neurology Edition 6 p.259)

Papillitis
SpecialtyOphthalmology Edit this on Wikidata

Optic papillitis is a specific type of optic neuritis. Inflammation of the optic nerve head is called "papillitis" or "intraocular optic neuritis"; inflammation of the orbital portion of the nerve is called "retrobulbar optic neuritis" or "orbital optic neuritis".[1] It is often associated with substantial losses in visual fields, pain on moving the globe, and sensitivity to light pressure on the globe. It is often an early sign of multiple sclerosis.[2]

Papillitis may have the same appearance as papilledema. However, papillitis may be unilateral, whereas papilledema is almost always bilateral. Papillitis can be differentiated from papilledema by an afferent pupillary defect (Marcus Gunn pupil), by its greater effect in decreasing visual acuity and color vision, and by the presence of a central scotoma. Papilledema that is not yet chronic will not have as dramatic an effect on vision. Because increased intracranial pressure can cause both papilledema and a sixth nerve palsy, papilledema can be differentiated from papillitis if esotropia and loss of abduction are also present. However, esotropia may also develop secondarily in an eye that has lost vision from papillitis. Retrobulbar neuritis, an inflamed optic nerve, but with a normal-appearing nerve head, is associated with pain and the other findings of papillitis. Pseudopapilledema is a normal variant of the optic disk, in which the disk appears elevated, with indistinct margins and a normal vascular pattern. Pseudopapilledema sometimes occurs in hyperopic individuals.

Workup of the patient with papillitis includes lumbar puncture and cerebrospinal fluid analysis. B. henselae infection can be detected by serology. MRI is the preferred imaging study. An abnormal MRI is associated with a worse visual outcome.[3]
