Abstract Details
Purpose:
To determine the prevalence of refractive error types among children aged 5 to 15 years living in Sumgait city of Azerbaijan Republic.
Setting:
Door-to-door recruitment of participants used disproportionate random sampling in 6-month increments.
Parental questionnaires were administered.
3091 children were examined.
Cycloplegia data were available for 1364 boys and 1727 girls.
Methods:
Participant eye examinations included LogMAR visual acuity,
Cycloplegic autorefraction,
IOL Master biometry.
Overall and age-specific prevalence of
myopia (spherical equivalence [SE] ≦ -0.50 diopters [D]),
high myopia (SE ≧ 6.00 D),
hyperopia (SE ≧ +3.00 D),
astigmatism (cylinder ≧ 1.50 D),
anisometropia (SE difference between each eye ≧ 2.00D) was calculated.
Results:
Low myopia prevalence was 18,18% among girls and 10,22% among boys. Moderate myopia prevalence was 3,23% among girls and 1,29% among boys. High myopia (at least -6.00 D) prevalence was 0,18% among girls and 0,38% among boys.
Prevalence of low hyperopia was 6,72% among girls and 6,34% among boys. Moderate hyperopia prevalence was 1,00% among girls and 1,61% among boys. High hyperopia prevalence was 0,9% among girls and 1,16% among boys.
Most astigmatism was with-the-rule (cylinder axes between 10 and 15 or 165 and 180).
Prevalence of anisometropia was 0,58% among girls and 1,16% among boys. Prevalence increased with title for astigmatism (p<0.001).
Conclusions:
Prevalence of myopia and astigmatism among children living in Sumgait city of Azerbaijan Republic is high, and low for hyperopia.
Age effects were observed for astigmatism, age-related variation in myopia prevalence may be influenced by ocular development, environment.
