RESUMEN
To compare body mass index [BMI] in patients with exfoliation syndrome [XFS] and a matched control group.In a cross-sectional study, 84 patients with XFS [XFS group] and 84 persons without XFS [control group] were matched for sex and age and selected sequentially. BMI was compared in the two groups. Patients with XFS with or without glaucoma and other complications were included. Mean age of patients was 62.8 +/- 9.1 [47-84] years. Unilateral involvement was observed in 78% of women and 54% of men. BMI was 20.52 +/- 3.94 in the XFS group and 22.84 +/- 4.55 in the control group [P= 0.005]. Patients with XFS have lower BMI than patients without this syndrome. Factors such as malnutrition, malabsorption, or other systemic disorders may play a role in the etiology of pseudoexfoliation
