| dc.description.abstract | The prevalence of low vision increases substantially in older adults with significant physical and psychosocial effects. The assessment of vision-related functioning for these individuals is vital. Clinical measures (visual acuity, contrast sensitivity, visual field) are poor predictors of the everyday impact of low vision. Consequently, self-report and performance-based measures have been developed to assess the perceived ability to perform activities of daily living (ADLs) and quality of life (QOL). Objective: The study aims to contribute to literature through systematic review of the effectiveness of self-report functional assessments for older adults (aged 65+) with various low vision conditions. Method: Fifteen studies were selected from a systematic search of PubMed, PsycINFO and Scopus databases using a formulated search strategy. Studies were coded and their methodological quality assessed. Results: Self-report measures demonstrated significant associations with clinical measures of visual function and low vision rehabilitation/treatment outcomes. Key barriers identified across studies (resilience/adjustment, familiar vs unfamiliar setting and the type of low vision) may impact the ability of these measures to effectively evaluate functional performance. Factors underpinning identified barriers (psychological distress, neuroticism, cognition, coping strategies) can result in differences in perceived functioning for older adults, independent of the effects of low vision. Conclusion: This review highlights the limitations of relying solely on self-report measures for older adults with low vision. Future research should develop further hybrid measures; incorporating performance and self-report assessments and consider effects of non-visual health on older adults' functional performance.
