ABSTRACT

· Alzheimer's disease (AD) is a neurodegenerative disease and is the most common type of dementia.It impairs the quality of life of a person and their family,posing a serious economic and social threat in developed countries.A high degree of clinical suspicion is needed to correlate problems in cognition with the changes in the eye.But relations between sensory functions and Alzheimer's disease are still under explored.When function of cognitive decline,patients perceive the world around them with their visual sense,while the brain can't integrate the sensory information to understand the surrounding environment.Visual dysfunction has long been recognized as a manifestation of Alzheimer's disease (AD).To further explore the changes in its visual function,it is now reviewed in various literatures to explain the visual impairment of patients with Alzheimer's disease.
