Abstract

Purpose: To evaluate the tear secretion in children with and without refractive error from 5 - 15 years.

Methodology: A case control, non-probability convenient study was carried out 150 individual patients with and without refractive error divided into two equal groups. Objectively assessment include Schirmer’s test-1 without anesthesia (ST-1) were performed on visit at hospital.

Results: Total 150 patients, 111 participant’s age between 10-15 years, and 86 of the participants were female and 64 were male. 75 Emmetropic children’s visual acuity was 6/6 and 75 patients’ vision was 6/9 to 6/60. 75 refractive error 36 (23.6%) myopia, Astigmatism 31 (20.3%) and Hypermetropia 8 (6.1%). Degree of ST-1; normal 26 (76.8%), mild 8 (20.3%), moderate 01 (1.4%) and severe 01 (1.4%) in Myopia, and normal 4 (60.0%), mild 01 (10.3%), moderate 01 (10.3%) and severe 02 (19.4%) in Hypermetropia, finally normal 24 (79.0%), mild 04 (12.0%), moderate 02 (6.0%) and severe 01 (3.0%) in Astigmatism. Degree of ST-1; normal 48 (58.3%), mild 10 (15.0%), moderate 13 (20.3%) and severe 04 (6.4%) in Emmetropia. The P-value between refractive error and without refractive error was 0.005, respectively.

Conclusion: Both children (with refractive error and without refractive error) had dry eyes but emmetropic children had greater effect of dryness rather than patients had refractive correction. Whereas in refractive error patients’ myopia had greater effect on dry eye than hypermetropia and astigmatism.
