systematic review and meta-analysis aimed to evaluate the global prevalence of OT.

Five English (PubMedScopusScienceDirectWeb of Science, and Google Scholardatabases were explored and 101 articles met the inclusion criteria.

The pooled prevalence (95% confidence interval) of OT was higher in immunological studies (9%. 6-12%) than in studies that applied ophthalmic examination (1%. 1-2%). The lower middle income country had the highest prevalence (6%. 2-12%) as well as the African region (10%. 7-13%). The highest infection rate (4%. 2-7%) was detected in the 1-25 mean age group.
