Purpose To determine the prevalence of amblyopia, strabismus, and ptosis among schoolchildren in Dezful in the west of Iran. Methods In this cross-sectional study, 1,375 schoolchildren of Dezful were selected through multistage cluster sampling. After obtaining written consents, participants had uncorrected and corrected visual acuity tests, cycloplegic refraction, and the cover test, and were examined for ptosis at the school site. Results Of the 1,151 study participants (83.7%), examinations were completed for 1,130 schoolchildren. Prevalence rates of amblyopia, strabismus, and ptosis were 2.7% (95% confidence interval [CI] 0.8-4.7), 1.9% (95% CI: 0.2-3.8), and 0.8%, respectively. Anisometropia was the most common cause of amblyopia; 45.2% of cases had anisometropic amblyopia. Among cases with strabismus, 63.6% were exotropic and 36.4% were esotropic. Conclusion The present study indicated that the prevalence of amblyopia and strabismus in Dezful schoolchildren falls in the average range. Since the Amblyopia Screening Program has been running for years, we expected lower rates compared to previous years, but this was not observed. Correcting refractive errors can significantly reduce amblyopic cases.
