Eye movements in patients with neurodegenerative disorders

Abstract

The neural pathways and brain regions involved in eye movements during ocular fixation and gaze control include the cerebrum, brainstem and cerebellum, and abnormal eye movements can indicate the presence of neurodegeneration. In some patients, oculomotor signs are key to making a diagnosis. Careful clinical examination of eye movements in patients with neurodegenerative disorders is, therefore, an invaluable adjunct to neurological and cognitive assessments. Eye movement recordings in the laboratory are generally not necessary for diagnostic purposes, but can be a useful addition to the clinical examination. Laboratory recordings of eye movements can provide valuable information about disease severity, progression or regression in neurodegenerative disease, and hold particular promise for objective evaluation of the efficacy of putative neuroprotective and neurorestorative therapies. For example, aspects of saccade performance can be tested to probe both motor and cognitive aspects of oculomotor behaviour. This Review describes the oculomotor features of the major age-related movement disorders, including Parkinson disease, Huntington disease, dementia and other neurodegenerative disorders. Findings in presymptomatic individuals and changes associated with disease progression are discussed.

Key Points

  • Careful clinical examination of eye movements is a useful adjunct in the diagnosis of many neurodegenerative disorders; laboratory eye movement recordings do not usually provide diagnostic clues

  • Different saccadic paradigms and laboratory recordings precisely reflect cognitive and motor characteristics of neurodegenerative disorders and may be useful biomarkers of disease severity and progression, especially in dementia

  • Clinical oculomotor examination in Parkinson disease indicates subtle saccadic hypometria and mildly impaired smooth pursuit, whereas laboratory recordings show voluntary saccadic abnormalities that correlate with cognitive status

  • Atypical parkinsonian disorders are associated with distinctive features: slowed saccades in progressive supranuclear palsy, positional and head-shaking downbeat nystagmus in multiple system atrophy, and saccadic apraxia in corticobasal syndrome

  • Specific oculomotor hallmarks that aid diagnosis in spinocerebellar ataxia (SCA) are very slowed saccades in SCA2 and SCA7, positional downbeat nystagmus in SCA6, and hypoactive vestibulo-ocular reflex in Friedreich ataxia

  • Future work is needed to explore the robustness and repeatability of laboratory eye movement recordings in healthy controls and disease states
