Résumé
Purpose
To investigate the association between visual crowding and vision-related quality of life (QoL) in patients with glaucoma.
Methods
This cross-sectional study included 50 patients diagnosed with POAG. Visual crowding was quantified by measuring the critical spacing (Scritical). The Scritical was assessed in each visual field quadrant. For each eye, a global Scritical was calculated as the mean of the eligible quadrant-specific values. Vision-related QoL was assessed using the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25), scored using Rasch analysis. Associations between the Scritical and the NEI VFQ-25 Rasch-calibrated scores were examined using generalized estimating equations, with multivariable models adjusted for age and standard automated perimetry 24-2 mean deviation.
