Background and Objective: This study investigates stereopsis and its correlation with refractive errors in Iranian 7-year-old schoolchildren.
Methods: This cross-sectional study included 3,675 first-grade primary school students in seven cities of Iran. The subjects were randomly selected and evaluated after obtaining an informed consent letter from their parents. There were two inclusion criteria: no systemic diseases and no medication use. Refractive errors were examined with an auto refractometer and stereopsis was measured using the TNO test. Data were analyzed by SPSS 21 and using independent t-test, ANOVA, and post hoc tests.
Results: The results of the present study showed that the rate of stereopsis in all students was 43.97±11.75 arcsec and there was a significant difference between the mean of stereopsis in females (43.30±10.62 arcsec) and males (44.59±12.66 arcsec) (P<0.001). There was also a significant difference between different types of refractive errors (myopia, ametropia, hyperopia) and stereopsis (P=0.001).
Conclusion: According to the results of the present study, girls had a better stereopsis rate than the boys. Also, after correction of refractive errors, stereopsis was not the same value in different refractive states, which could be an indication of more attention to stereopsis testing as an indicator of binocular vision performance.
