The Association Between Visual Impairment and Delirium: A Systematic Review and Meta-Analysis

This systematic review and meta-analysis aimed to evaluate the association between visual impairment and the risk of developing delirium across various clinical settings. The findings indicate that visual impairment is linked to increased odds of delirium, with an odds ratio of 2.02 in adjusted analyses, although the evidence is rated as low certainty due to significant heterogeneity among studies. The authors highlight that while visual impairment may serve as a prognostic factor for delirium, causality has not been established, and further research is needed to determine if treating visual impairment can reduce delirium incidence.
