A Study On Refractive Errors Of A Random Population Selected From Urban Areas Of Visakhapatnam, India

摘要

A statistical study has been conducted on an endemic population of 322 young adults (in the age group 17-21)in the area of Visakhapatnam, India to establish statistical correlations between the presence of a refractive error and the most implicated risk factors : Diet, Heredity, Reading/Studying, Television watching and Exercise. In the randomly selected population, 95 (29.5%) subjects suffered from Myopia, 9 from Hypermetropia and the rest did not report any defect. There was found to be a statistically significant link between refractive error presence and television watching, diet, presence of a defect in the mother of the subject where as there was no link between refractive error presence and the amount of reading, or the quantum of exercise the subject indulged in.
