Abstract Details

Purpose:

To evaluate prevalence of different types of refractive errors in adult population of Tehran

Setting:

Tehran , Iran , Winter 2013

Methods:

Population based Study; Random cluster sampling of Tehran population aged over 10, 2013 849 people were included in the study. Emmetropia was defined as refractive error between +/-0.5 D Myopia was defined as bilateral refractive error (spherical equivalent) less than -0.5D, Hyperopia as bilateral refractive error > +0.5D, Unilateral myopia or hyperopia as one eye myopia or hyperopia with the second eye being emmetropic and Antimetropia as one eye being hyperopic with the second eye being myopic.

Results:

Prevalence of refractive errors was as follows: • Emmetropia: 34.7% • Myopia: 33.2% • Hyperopia: 12.6% • Unilateral myopia: 13% • Unilateral hyperopia: 5.2% • Antimetropia: 1.3%

Conclusions:

Prevalence of refractive errors are higher than previously thought in adult population of Tehran. FINANCIAL INTEREST: NONE
