Purpose: To estimate the prevalence of Pseudoexfoliation syndrome (PXF) and to investigate its relationship with systemic and ocular diseases and lifestyle factors in a general adult population in north-western Spain. Methods: An age-stratified random sample of 1155 subjects was drawn from the population aged 40 years and over of O Salnes (Spain). From 937 eligible subjects, 619 (66.1%) participated (mean age (Standard Deviation [SD]): 63.4 (14.5) years, range: 40-96, 37.0% males). An interview to collect past history of ocular and systemic diseases and lifestyle details, and a comprehensive ophthalmic evaluation were performed. Study subjects with typical pseudoexfoliative material on the anterior capsule or in the pupil margin were labelled as having PXF. A design based analysis was performed and all calculations were weighted to give unbiased estimates. Results: The prevalence of PXF was 6.5% (95% confidence interval [CI]:4.9-8.1). PXF rates increased significantly with age (P = 0.000). No cases of PXF were detected in subjects between 40 and 60 years. Prevalence of PXF was 8.0% (95% C I5.4-11.6) in men and 5.4% (95% CI 3.8-7.6) in women (P = ns). The prevalence of glaucoma in subjects with PXF was 19.6% (95% CI 8.2-40.0). After controlling for age and sex, glaucoma, cataract surgery, rose bengal staining and diabetes were associated with PXF but only glaucoma and rose bengal staining associations remained significant in a multivariate model. Conclusions: PXF is common among older individuals in north-western Spain. Subjects with pseudoexfoliation have a significantly higher prevalence of glaucoma than subjects without. An abnormal ocular surface detected by rose bengal staining is highly prevalent among subjects with pseudoexfoliation.
