Abducens palsy, also known as sixth nerve palsy, is a dysfunction of cranial nerve VI, which is respon-sible for contracting the lateral rectus muscle to abduct the eye. Patients with abducens palsy have horizontal diplopia that worsens with gaze toward the paretic lateral rectus muscle. The condition is commonly uni-lateral but can also occur bilaterally. Abducens palsy is the most common ocular motility palsy.1 In a popula-tion-based study including all patients who had the onset of sixth nerve palsy between January 1, 1978, and December 31, 1992, the age- and sex-adjusted annual incidence of abducens palsy was reported to be 11.3 per 100 000 patients.2 The causes and associated conditions were unknown (26%), hypertension (19%), combination of hypertension and diabetes (12%)
