Tehran , Iran , Winter 2013


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.


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%


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