Ocular toxocariasis (OT) is a zoonotic infection caused by larval stages of Toxocara canis and T. cati.
A systematic review and meta-analysis aimed to evaluate the global prevalence of OT.
Five English (PubMed, Scopus, ScienceDirect, Web of Science, and Google Scholar) databases 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.
