To investigate if adaptation to vision loss (AVL) was independently associated with overall and specific aspects of vision-related quality of life (QoL) in older Australian adults with low vision.
Participants were aged 58 and over, had presenting visual acuity (VA) 1.0 LogMAR), and 58.7% female) participated in the study. In multivariable linear regression models, AVL score was independently associated with the total IVI score (coefficients [β]=1.60, 95% confidence interval [CI]: 1.02, 2.18, p<0.001), and three IVI subscales (reading and accessing information, mobility and independence, and emotional well-being) (β [95% CI]:1.67 [0.73, 2.63]; 2.69 [1.69, 3.70] and 2.25 [1.26, 3.24], respectively, all p<0.001) after adjustment for age, gender, marital status, educational level, living arrangement, VA, duration of low vision, and comorbidity. The AVL explained 32%, 19%, 29%, and 25% of the variance in total IVI and three subscales, respectively. After adjustment for similar covariates, AVL score was not associated with duration of low vision (β [95% CI]:0.07 [-0.09, 0.22].
Better adaptation to vision loss was significantly associated with better QoL. These findings suggest that improve intervention to adaptation to vision loss can help to promote a better QoL in older people with low vision.
