Abstract
Smooth pursuit eye movements were studied with infrared reflection equipment in 10 patients with myotonic dystrophy and in 10 age- and sex-matched controls. Smooth pursuit gain, measured after correction for catch-up saccades, was decreased in the patient group Normal latencies of saccadic eye movements made a lack of attention an unlikely explanation for this low gain Likewise, presence of catch-up saccades and normal fixation made it unlikely that extra-ocular myopathy explained the low smooth pursuit gain We suggest that periventricular white matter abnormalities represent a more likely explanation.
