Background: National Programme for Controlling Blindness in India is encouraging Vision Screening for refractive errors among school children by teachers. Objectives: 1. To find out whether the vision screening conducted by school teachers will be of acceptable quality or not? 2. To find out whether the school environment will influence the eye-health of the school children or not? Methods: Settings and Design: School setting, Cross -sectional descriptive study. Eighty Teachers were trained by the ophthalmologists to test for refractive errors and to detect other eye diseases. These teachers screened 5193 schoolchildren. Screening was repeated by an ophthalmologist assisted by two ophthalmic assistants, to assess the quality of teachers’ screening. Statistical techniques: Cluster sampling, Proportions, X2 test, Confidence intervals; Cohen’s Kappa statistic. Results: The vision screening done by the school teachers was found to be of acceptable quality. (Excellent inter -rater agreement with specialists’ screening. Kappa statistic 0.993 for defective Vision and 0.867 for other eye diseases). Refractive errors and other eye diseases were significantly more seen in the schools with poor Sanitation 62 (1.19%), 214 (4.13%) respectively. Overall prevalence of Refractive errors was 85 (1.63%): Myopic 59(1.14) Hypermetropic 12 (0.23%) Astigmatic 11 (0.21 %) and Amblyopic 3 (0.05%) Overall Prevalence of other Eye diseases was 375 (7.23%). Xerophthalmia 156(3%), Conjunctivitis 148(2.8%), Proptosis 19(0.36%) Squint 13(0.14%), Phlycten 10 (0.25%). Conclusion: Vision screening by teachers was of acceptable quality.
