Purpose:
|
To determine the prevalence of amblyopia, refractive errors and strabismus among 7-12 years primary schools children of Tehran in 2013.
|
Methods:
|
This population based cross-sectional survey was performed on 2410 students from 40 randomly selected primary schools of Tehran. Visual acuity (VA) was tested by yang vision tester Snellen E-optotype. Refractive error was measured by photorefractometer with no cycloplegia. Strabismuswas checked by cover test and EOM functions testing. Direct ophthalmoscope was used for observing anterior segment, lens opacities, Red-Reflex and fundus. 90 students were referred to Imam Hossein Medical Center to compare autorefraction (+/- cycloplegia) results with photorefraction.
|
Results:
|
Amblyopia was found in 2.3% of cases (VA≤20/40) with no difference between two genders but higher in younger ages. The prevalence rates of hyperopia≥+2.00D, myopia≤-0.50D, astigmatism≥0.75D and anisometropia (SE difference≥1.00D) were 3.5%, 4.9%, 22.7% and 3.9%, respectively. By increasing age, hyperopia decreased, myopia increased and astigmatism remained same. Strabismus was found in 2.3% of cases. Strabismus, anisometropia and hyperopia were important amblyopicrisk factors in our study.
|
Conclusion:
|
High amblyopia prevalence of 2.3% in our primary school children revealthe necessity of applying preventive and effective treatments, on-time screening with more sensitive methods for early detection and treatment seems essential for this purpose.
