There is little prior evidence on prevalence of strabismus in Iran. Thus, this study was undertaken to investigate the prevalence of strabismus types in Azad University students aged 18-25 years in South West Iran. A total of 752 of 826 students participated in the study with a response rate of 91.4%. Mean age was 21 ±3 years with 51.65% female. Refractive errors were myopia, hypermetropia and emmetropia in 41.8%, 2.75% and 55.37% respectively. Prevalence for heterotropia, exotropia and esotropia was 1.5%, 1.2% and 0.3%. There was a significant increase in prevalence of esotropia with age group. Prevalence of exotropia was significantly higher in females and in myopes. Prevalence for heterophoria, exophoria and esophoria was 12.9%, 11.7% and 1.2%. The results show prevalence of strabismus in Iranian students which is similar to prevalence figures in the Iranian general population, but lower than prevalence on other countries.
