Pseudoexfoliation: Normative Data and Associations. The Central India Eye and Medical Study: e76770

Purpose To assess the prevalence of pseudoexfoliation (PEX) and its associations in a population-based setting. Design Population-based, cross-sectional study. Methods The Central India Eye and Medical Study included 4711 individuals. All study participants underwent a detailed ophthalmological examination. After medical pupil dilation, PEX was assessed by an experienced ophthalmologist using slit-lamp based biomicroscopy. Results Slit lamp examination results were available for 4646 (98.6%) study participants with a mean age of 49.3 plus or minus 13.3 years (range: 30-100 years). PEX was detected in 87 eyes (prevalence: 0.95 plus or minus 0.10% (95%CI: 0.75, 1.15) of 69 subjects (prevalence: 1.49 plus or minus 0.18% (95%CI: 1.14, 1.83). PEX prevalence increased significantly (P
