Glaucoma was identified through self-report, retinal imaging, and frequency doubling technology visual field testing, with a clinical diagnosis based on Rotterdam criteria. Multivariable logistic regression models adjusted for covariates were used. The central result showed that dietary Ca consumption meeting recommended levels was associated with a decreased risk of glaucoma (OR=0.59, 95% CI 0.42–0.81), and this association held for individuals both with and without hypertension. Additionally, dietary K intake was a potential protective factor for glaucoma in non-hypertensive populations (OR=0.47, 95% CI 0.22–0.99, P=0.049). Subgroup analyses suggested potential protective associations for Ca, K, and Mg in individuals aged <65 years or with/without visual field defects. The study's limitations include its cross-sectional design, which precludes causal inference, and the use of self-reported glaucoma for some participants.
