To determine the association between distance and near visual acuity (VA) and cognitive function among older adults in Selangor, Malaysia.
A total of 230 older adults (age ≥60y) participated in this study. Habitual distance and near VA were measured using the Early Treatment Diabetic Retinopathy Study Chart and Lighthouse Near Visual Acuity Chart, respectively. Global cognitive function was assessed using the Mini-Mental State Examination (M-MSE) and the Malay language version of the Montreal Cognitive Assessment (M-MoCA). Digit Symbol (DS) subtest was used to measure information processing.
No significant association was observed between vision and M-MSE and M-MoCA scores. However, poor distance and near VA were found to be significantly associated with low DS scores [distance VA: =-0.01, =0.1, =0.02; odds ratio (OR)=2.84, 95% confidence interval (CI), 1.10-7.33, =0.03; near VA: =-0.05, =0.08, =0.00; OR=3.32, 95%CI, 1.28-8.59, =0.01].
Poor vision is associated with a decline in information processing in older adults and substantiates the importance of preserving good vision in maintaining cognitive function.
确定马来西亚雪兰莪州老年人的远视力和近视力与认知功能之间的关联。
共有230名老年人（年龄≥60岁）参与了本研究。分别使用糖尿病视网膜病变早期治疗研究视力表和灯塔近视力表测量习惯性远视力和近视力。使用简易精神状态检查表（M-MSE）和蒙特利尔认知评估马来语版（M-MoCA）评估整体认知功能。数字符号（DS）分测验用于测量信息处理能力。
未观察到视力与M-MSE和M-MoCA评分之间存在显著关联。然而，远视力和近视力较差与DS评分较低显著相关[远视力：=-0.01，=0.1，=0.02；优势比（OR）=2.84，95%置信区间（CI），1.10-7.33，=0.03；近视力：=-0.05，=0.08，=0.00；OR=3.32，95%CI，1.28-8.59，=0.01]。
视力差与老年人信息处理能力下降有关，证实了保持良好视力对维持认知功能的重要性。
