Bedside and electro‐oculographic analysis of abnormal ocular movements in spinocerebellar degenerations

Abstract
We studied ocular movements in 130 patients with spinocerebellar degenerations. Patients had blurred vision (33. 3%), diplopia (40. 2%), oscillopsia (18. 6%), ocular flutter (22. 3%), rebound nystagmus (25. 4%), square-wave jerks, (29. 2%), macro square-wave jerks (6. 2%), and macro saccadic oscillations (10. 8%). Electro-oculographic abnormalities included reduction of saccadic velocity, dysmetria, and saccadic smooth pursuit. All the abnormal movements were improved by the injection of thyrotropin-releasing hormone.
