Abstract

Purpose: To assess the correlation between REFRACTIVE ERROR and stereo acuity in school children.Methods: In this correlational study, 202 children with normal visual acuity and 104 children with REFRACTIVE ERROR and without amblyopia (90 myopic,4 hyperopic,4 astigmatic, and 4 anisome tropes) were included. All children were in 7-12 years age group and sex distribution was equal in two groups. Stereo acuity was measured for each child with the Titmus test at 40 cm distance. In children with REFRACTIVE ERROR, stereo acuity measurement was repeated after correction of the REFRACTIVE ERROR with spectacles.Results: Mean stereo acuity in the control group and in children with REFRACTIVE ERRORs before and after correction with spectacle were 43, 96, and 45 seconds of arc, respectively. Mean STEREOACUITY in children with REFRACTIVE ERROR before correction with spectacle was less than the control group (P<0.0001). After correction of the REFRACTIVE ERROR with spectacle the difference was not statistically significant. Correction of REFRACTIVE ERROR with spectacle resulted in improved stereo acuity to normal values in all types of REFRACTIVE ERRORs except anisometropia. There was no significant linear relationship between visual acuity of the worse eye and STEREOACUITY in children with REFRACTIVE ERRORs (r=-0.12, P=0.23).Conclusion: Uncorrected REFRACTIVE ERRORs especially anisometropia can significantly decrease STEREOACUITY in children. STEREOACUITY tests may be used for screening of REFRACTIVE ERRORs in children.
