Abstract

Parkinsonism is a clinical syndrome which encompasses basal ganglion diseases characterized by bradykinesia, tremor, rigidity and postural instability. Parkinson’s disease (PD) is the most common cause of neurodegenerative parkinsonism. Less frequent parkinsonian disorders include progressive supranuclear palsy, multisystem atrophy, corticobasal degeneration, and Lewy body dementia. In addition to motor symptoms, non-motor symptoms of parkinsonism syndrome also affect the quality of life of the patients. Non-motor symptoms include cognitive, neuropsychiatric, autonomic, sensorial manifestations and sleep disorders. Ophthalmologic complaints which are often recognized by patients contribute progressive disability. In this review, ophthalmological findings including abnormal eyelid movements, abnormal eye movements, visual dysfunction and visual hallucinations in patients with parkinsonian syndromes were discussed in light of the literature.
