  • Introduction: Purpose: This systematic review and meta-analysis summarizes the evidence for the association between Helicobacter pylori infection and primary open-angle glaucoma.
  • Methods: Methods: Eligible studies reporting an association between H. pylori infection and glaucoma were identified through an extensive search of the Excerpta Medica (EMBASE), Web of Science, Scopus, and PubMed databases, and a review of the reference lists of top articles up until October 2022. The analysis was performed using a random effects model in Stata 17.
  • Results: Result: The systematic review included 24 studies, comprising 1602 glaucoma patients and 2800 control individuals. The combined relative risks (RRs) of cohort studies and overall combined odds ratios (ORs) of case-control studies demonstrated a significant correlation between H. pylori infection and glaucoma. Subgroup analysis revealed that glaucoma patients had a higher risk of H. pylori infection if they were residents of European countries (Cohort: RR: 1.69; 95% CI: 1.3-2.19) and (Case-Control: RR: 3.71; 95% CI: 2.07-6.64), had primary open-angle glaucoma (POAG) (Cohort: RR: 1.76; 95% CI: 1.37-2.27) and (Case-Control: RR: 3.71; 95% CI: 2.93-4.70), were diagnosed with H. pylori infection using histology (Cohort: RR: 1.95; 95% CI: 1.26-3.01) and (Case-Control: RR: 4.06; 95% CI: 2.28-7.22), and were over 60 years old (Cohort: RR: 1.63; 95% CI: 1.33-2.00) and (Case-Control: RR: 2.95; 95% CI: 2.27-3.83).
  • Conclusion: Discussion: The meta-analysis results suggest a statistically significant association between Helicobacter pylori infection and primary open-angle glaucoma.
