Abstract

Purpose: Vision impairment is a common age-related condition and has been shown to be associated with impaired cognitive function, dementia and Alzheimer’s disease. However the relationship is not clearly understood. This study evaluates the correlation between distant vision and cognitive function in a sample of elderly population living in Malaysia.

Methods: A total of 464 elderly subjects (48.9% males, 51.1% females) with mean age 69±5 years volunteered for this study. Distant visual acuity (VA) was measured using Log MAR chart and the cognitive status was evaluated using the Malay version of Mini Mental Examination State (M-MMSE) and Montreal Cognitive Assessment (MoCABM). Data from the better eye was analyzed and VA ≤6/12 was considered normal.

Results: A total of 386 subjects had normal vision and 78 were visually impaired. Significant correlations were found between scores of M-MMSE with VA of visually impaired subjects (p=0.012) and between scores of MoCABM with VA of normal subjects (p=0.001).

Conclusion: The analysis indicates that specific cognition function correlate with good VA in specific group. The association found requires further investigation.
