Purpose: The purpose of this study is to assess the pooled prevalence of meibomian gland dysfunction (MGD) and evaluate its risk factors by gender, age, and ethnicity. Methods: Articles were searched reporting the prevalence of MGD from PubMed, Scopus, Web of Science, and Embase databases. Results: The estimated pooled prevalence of MGD was 0.358 (95% CI 0.26–0.46; I2: 99.57%). The prevalence of MGD was 0.358 (95% CI 0.24–0.50) in clinical and 0.359 (95% CI 0.22–0.52) in population-based studies. Men were more prone to MGD than women (OR: 1.24, 95% CI 1.01–1.52, p = 0.034). The rate of MGD was between 21.2% and 29.5% in Africans and Caucasians, to 71.0% in Arabs, and 67.5% in Hispanics. Conclusion: MGD is a quite prevalent disorder with an estimated pooled prevalence of 35.8%. Men are more prone to MGD than women. There is a large variation between studies in terms of quality, sample size, age ranges, diagnostic criteria, and ethnicity. [ABSTRACT FROM AUTHOR]
