Specifi c Culomotor Disturbance in a Patient With Amyotrophic Lateral Sclerosis

A 67-year-old male patient was admitted to the hospital for pneumonia and respiratory insuffi ciency. Neurological examination showed lower and upper motor system involvement. One year and eight months after the initiation of artifi cial ventilation, he presented specifi c oculomotor disturbances. He predominantly showed slow eye movement: saccade speed was approximately 67 degree/second. Sometimes, he showed blink and neck rotation before he initiated saccades, or his saccades were undershoot or did not reach visual objects. He sometimes showed almost normal saccades, especially when he initiated saccades spontaneously (automatically). In this study, we have reported slow eye movement (saccades disturbances) with automatico-voluntary dissociation of an amyotrophic lateral sclerosis (ALS) patient.
