Purpose:
|
To determine the prevalence of amblyopia in 7-year-old schoolchildren in Iran
|
|
Methods:
|
In this cross-sectional study, cluster sampling was done from elementary school students in seven cities in Iran. In all schools, an optometrist conducted all tests including measurement of uncorrected and corrected visual acuity, cycloplegic refraction, and cover test.
|
|
Results:
|
Of the 4157 students selected for the study, 3675 participated and final analyses were done with data from 3547 children. The prevalence of amblyopia was 1.88% (95% CI: 1.24-2.52)(n=63). The prevalence was 1.91% (95% CI: 0.85-2.97) in boys and 1.85% (95% CI: 1.12-2.58) in girls (p=0.92). Among these cases, 60.30% (n=38) were unilateral. Also, 61.9% were strabismic, 27.0% were anisometropic, 9.5% were isometropic, and one case (1.6%) was due to congenital cataracts.

Conclusion:
|
Necessary attention should be paid to amblyopia although its prevalence in Iran is mid-range when compared with other countries. Amblyopia is more common in hyperopic and astigmatic individuals and therefore it is important to pay more attention to this refractive error during childhood. Since strabismus is the most common cause of amblyopia in Iran, children need to be checked for strabismus before the age of 5 years old.
