Abstract

Study design: Prospective observational study
Purpose: To study the effect of digital screen time on progression of myopia and evaluate the changes in axial length with myopic shift
Methods: A total of 196 children with physiological myopia between age group of 5-18 years were taken up. Study duration was 1.5 years. Children with pathological myopia, amblyopia, strabismus, retinal and congenital disorders were excluded. Cycloplegic refraction, fundoscopy, axial length measurements were done. Follow up at 6 months.
Result: 172 children had myopic shift with mean screen time of 6.45 hours, mean change in spherical equivalent of -0.87D and mean change in axial length of 0.25mm
Conclusion: Children with more screen time had more myopic shift (r=0.58, p<.0001). Also, changes in axial length was positively correlated with myopic progression (r=0.94, p<.0001)
