Visual Function and Visual Perception among Senior Citizens with Mild Cognitive Impairment in Taiwan

Area of Science:

• Gerontology
• Neuroscience
• Ophthalmology

Background:

• Taiwan is transitioning to a super-aged society.
• Mild cognitive impairment (MCI) affects 15-20% of individuals over 60.
• Understanding factors influencing cognitive decline in the elderly is crucial.

Purpose of the Study:

• To investigate the relationship between cognitive function and visual function (binocular vision, visual perception) in older Taiwanese adults.
• To identify specific visual parameters that predict cognitive function.

Main Methods:

• Recruited 36 healthy participants aged 60+ without cognitive or visual impairments.
• Administered Addenbrooke's Cognitive Examination III (ACE-III).
• Assessed binocular visual function and visual perception, analyzing data with statistical methods including linear regression and MANOVA.

Main Results:

• A significant correlation was found between cognitive function and visual function/perception.
• Binocular eye movement adjustment time, stereopsis, MVPT-4, and peripheral awareness showed strong predictive power for cognitive function.
• Interactions between visual function and perception influenced specific ACE-III cognitive domains.

Conclusions:

• Cognitive function is strongly associated with visual function in older adults.
• Visual function assessment may aid in predicting cognitive status and identifying potential mild cognitive impairment.
