Objective: Quality of vision plays an important role in everyday living, and low vision (LV) can take a toll on individual's quality of life (QOL). The objective of this paper is to evaluate the impact of LV on QOL and depressive symptoms in LV patients compared with healthy controls.
Design: Systematic review and meta-analysis.
Methods: Literature was systematically searched to obtain all relevant records. Covidence software was used to conduct the systematic review. Duplicate records were removed, and 2 independent reviewers screened records for relevance. After screening, risk of bias assessment was carried out. Data were extracted and meta-analysis was performed using STATA 15.0. Fixed-effect and random-effect models were computed based on heterogeneity.
Results: In total, 2870 records were retrieved from database and grey literature searches. Twelve articles (35 341 subjects) were included for quantitative analysis. Overall, the QOL of LV patients was significantly lower compared with healthy individuals. Common QOL questionnaires, including 25-item visual function questionnaire (VFQ-25) (standard mean difference [SMD] = 0.91, confidence interval [CI]: [0.42-1.40]), 36-item short form survey (SMD = 0.53, CI: [0.26-0.80]), VFQ-14 (SMD = 0.58, CI: [0.42-0.74]), and visual function QOL questionnaire (SMD = 0.68, CI: [0.54-0.82]), demonstrated a poor QOL in LV patients compared with healthy controls. Additionally, odds of depressive symptoms were significantly greater (odds ratio = 2.25, CI: [1.58-3.21]) in LV patients compared with controls.
Conclusion: LV patients demonstrated a poor QOL and higher odds of depressive symptoms compared with healthy controls.
