Third nerve palsy

Abstract

Partial or complete palsies of the oculomotor nerve are not common but are somewhat more frequent than many neuro-ophthalmologic abnormalities. Interest in oculomotor nerve palsies, therefore, is not driven by the frequency of these events but rather by the relatively large number of different pathologic mechanisms that can be involved and the potential severity of some of these diagnoses. A correct diagnosis is important in devising the correct treatment.
