Parkinson’s disease (PD) is the second most common neurodegenerative disease, and its clinical manifestations include motor and non-motor symptoms. Non-motor symptoms have a significant impact on the quality of life of patients and may predict disease progression and possible outcomes. Visual impairment is one of them, including visual acuity, contrast sensitivity, color vision, visual field, stereoscopic vision, eye movement, blink reflex, pupillary response, visual hallucination, etc., which has a significant impact on the life quality of patients. This article provides a brief review of the clinical manifestations, pathological manifestations, auxiliary examinations, and drug treatment of visual impairment in PD, which helps to facilitate early diagnosis of PD.
