Abstract
We studied eye movements in 50 patients with Huntington's disease. Fixation was impaired in 73% of patients; such individuals had difficulty in suppressing saccades toward novel visual stimuli. Impaired initiation of saccades was manifest by increased reaction time (89%) and inability to make a saccade without head movements (89%) or blink (35%). Saccades and quick phases of nystagmus were slowed in 62%. Smooth pursuit was abnormal in 60%, and vergence in 33%. The vestibulo-ocular reflex and the ability to hold eccentric gaze were preserved even late in the disease.
