A case of sudden-onset isolated inferior rectus paresis is described. This is a rare presentation of isolated oculomotor nerve paresis and its features are described. Lesions of the oculomotor nerve can affect any of the functions of the extraocular muscles depending on the location and the aetiology of the lesion. An interesting subgroup of patients having isolated paresis of inferior rectus muscle without involvement of the other muscles has always drawn special interest. The purpose of this article is to report a case of binocular vertical diplopia resulting from an isolated, unilateral inferior rectus paresis followed by a review of the existing literature along with a discussion of neuroanatomy, aetiology, clinical features and management. Clinicians may increase their awareness of the spectrum of various possible causes that can present with isolated IRM palsy.
