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).
