E diagnosis of ocular motor palsy enables prognosis and assists in treatment. In adults, the most common causes of ocular motor palsy are aneurysm, microvascular disease (such as diabetes mellitus [DM]), and trauma. In patients with DM, ocular motor nerve palsy is a common cause of acquired diplopia and/or ptosis.1,2 In diabetics, the calculated incidence of cranial nerves palsies is 5-10 times...

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 movement (89%) or blink (35%). Saccades and quick phases of nystagmus were slowe...

OBJECTIVE To detect disconjugate ocular motor abnormalities and a possible extraocular muscle myotonic phenomenon in patients with myotonic dystrophy (MyD). METHODS The magnetic scleral search coil technique was used to record monocularly the small (25 degrees ) and large (50 degrees ) saccades, which were paced to two interstimulus intervals (ISIs), one short (1 s), the other long (5 s). The...

We review here the eye movements in patients with Huntington's disease (HD), concentrating upon saccades as they show the most prominent abnormalities. Inability to suppress reflexive glances to suddenly appearing novel visual stimuli and delayed initiation of voluntary saccades, including predictive saccades, are early and consistent findings. These two abnormalities can be interpreted in the ...

PU R P O S E. Ocular trauma is one of the main causes of visual reduction or loss, particularly in the younger population. ME T H O D S. In this prospective study the authors included 67 consecutive patients with ocular trauma secondary to motor vehicle accidents who were hospitalized in the Athens University Eye Clinic from September 1993 to December 1996. The mean follow-up time was 31 months...

Eye-head coordination was measured in patients with Parkinson's disease as they made horizontal gaze shifts in response to predictable and unpredictable target steps and to targets moving smoothly with either constant or sinusoidally varying velocity. Patients preferred not to move their heads for both large and small amplitude gaze shifts. Both eye and head movement reaction times were prolong...
