N2 - Purpose: To investigate the impact of Charles Bonnet syndrome (CBS) on vision-related quality of life (VRQoL) in patients with glaucoma. Design: Cross-sectional cohort study. Participants: Twenty-four patients with CBS and 42 matched controls without CBS out of 337 patients with open-angle glaucoma (OAG) with visual field (VF) loss. Methods: A matching technique was used to identify control patients with similar disease stage, best-corrected visual acuity (BCVA) and age to patients with CBS. Patients’ VRQoL was determined using the National Eye Institute Visual Function Questionnaire 25 (NEI VFQ-25). Rasch-calibrated NEI VFQ-25 scores of the CBS group and the control group were compared. Uni- and multivariable regression analysis was used to evaluate the impact of different factors on VRQoL. Main Outcome Measures: Vision-related quality of life in patients with glaucoma with CBS and without CBS. Results: Vision-related quality of life scores were significantly lower in the CBS group than in the control group on both the visual functioning scale with 39 points (95% confidence interval (CI): 30–48) vs. 52 points (95% CI: 46–58) (P = 0.013) and on the socioemotional scale with 45 points (95% CI: 37–53) vs. 58 points (95% CI: 51–65) (P = 0.015). Univariable regression analysis showed that integrated visual field mean deviation (IVF-MD) (r2 = 0.334, P < 0.001), BCVA in the better eye (r2 = 0.117, P = 0.003), and the presence of CBS (r2 = 0.078, P = 0.013) were significantly correlated to VRQoL scores on the visual functioning scale. Integrated visual field mean deviation (r2 = 0.281, P < 0.001), age (r2 = 0.048, P = 0.042), and the presence of CBS (r2 = 0.076, P = 0.015) were significantly correlated to VRQoL scores on the socioemotional scale. Multivariable regression analysis showed that IVF-MD and the presence of CBS accounted for nearly 40% of the VRQoL score on the visual functioning scale (R2 = 0.393, P < 0.001) and for 34% of the VRQoL score on the socioemotional scale (R2 = 0.339, P < 0.001). Conclusions: Charles Bonnet syndrome had a significant negative association to VRQoL in patients with glaucoma. Presence of CBS should be considered when evaluating VRQoL in patients with glaucoma.
