Ocular fixation instabilities in motor neurone disease [PDF]

Journal of Neurology, 2009
Objective Eye movements are classically felt to be spared in motor neurone disease (MND). Although a range of ocular motor disorders have been reported, no consistent pattern has been established. Disturbances of ocular fixation have been noted in MND; however, fixation has not yet been formally examined.
