Those with a MoCA-Blind score of 6 years of education attainment, vision impairment was associated with a significant reduction of cognitive function and remained so after adjustment for age and gender (β = 1.863 95 % CI, 1.081-3.209 P = 0.025). Cognition was evaluated using the MoCA-Blind scoring procedure. Visual acuity (VA) was assessed with logMAR score with vision impairment defined as VA 6/18 or worse in the better-seeing eye. Data were obtained through a home-based interview and hospital-based health check by trained researchers. Subjects aged 55 years and above from the Malaysian Elders Longitudinal Research (MELoR) study with available information on vision and Montreal Cognitive Assessment (MoCA) scores were included.
