Third Nerve Palsy: An Overview.

ABSTRACT

Oculomotor nerve palsy may be congenital or acquired, complete or partial, pupil-sparing or pupil-involving, isolated or accompanied by signs of more extensive neurological involvement. Precise knowledge of its origin and course from nuclear level to terminal muscles along with accompanying clinical features helps in localizing the site of involvement and thus appropriate management. Associated symptoms are of extreme importance and patient should always be asked and assessed for headache, periocular or orbital pain.
