Abstract
Purpose: The prevalence of refractive error among student has increased due to home confinement hence this study was done to find out the association between digital screen time and myopia among medical student in teritary care center.
Method:A Cross sectional study was done among the medical students of a tertiary care center in Tamil Nadu from January 2022 to March 2022. Complete enumeration of all the 300 medical students from 3 different batches in the college were done.questions pertaining to the symptoms and diagnosis of refractory error and screen time was collected. The students who had symptoms suggestive of myopia were screened in the Opthalmology department of the institute. Association between quantitative variables were calculated by chi square test. P value < 0.05 considered statistically significant.
Result:The prevalence of myopia among medical students was 69.1%, in which 178 (66.1%) were known cases of myopia using spectacles / contact lens. Among those who were diagnosed case of myopia 70 (26%) had a refractory check up within last 1 year On this screening about 8 (3%) were newly diagnosed with myopia.(Figure 1) About 39 (14.4%) had progression of myopia in the last 1 year The mean duration of screen time among medical students was 10.3 ± 2.8 hours / day.
Conclusion:The study concluded that the prevalence of myopia among medical students and there was a significant association between digital screen time and myopia among medical students.This rapid rise of myopia is important public health issues and need urgent and special attention.
