Abstract
Refractive error, a problem that is easy to detect and treat, continues to be a major contributor to preventable visual impairment in today's society. It is considered as the second most common cause of blindness in India after cataract. The aim of the present study was to ascertain the refractive status and its correlation with anthropometry and ocular biometric parameters in Students in North Indian University. All study participants (18‐to‐25‐year students) were screened for their refractive status using Snellen’s chart, distant and near vision. Refractive error was measured and graded according to spherical equivalent power. Distance Jaeger’s chart was used for near vision. Retinoscopy was performed to determine the refractive error, along with phoropter refraction/ subjective refraction., to ascertain the presence and degree of myopia, hyperopia, or emmetropia. Corneal curvature, Anterior chamber depth and Axial length were measured by IOL Master and Central cornea thickness was measured by ultrasonic pachymeter. The results were analyzed using T‐test, correlation and multi variate linear regression to identify mean values and assess correlation between the specific anthropometric measurements and ocular biometric parameters. All variables were summarized by descriptive statistics followed by correlation testing by Pearson’s Correlation Coefficient r. Our study concluded that myopia was the most prevalent refractive error in medical students with 63% being myopic. Prevalence of ametropia, hypermetropia and Astigmatism was found at 33%, 1% and 3 % respectively. The Grading of Low, Moderate and High myopia was found to be approx. 60%, 33.3% and 6.1% respectively. Approx. 23% of respondents with myopia had positive family history (history of one or both the parents having refractive errors), whereas 77 % of myopic cases did not give any family history of refractive error. Axial length was found positively correlated in myopia cases {Pearson’s Correlation Coefficient ‘r’ value was 0.56 (rt), 0.58 (lt)}and was found to have increased in myopic respondents compared to ametropic respondents. Negative correlation was found between central corneal thickness and corneal curvature in our study across the different refractive errors in our study. No Significant Correlation was found between BMI and myopia in our study. Fair correlation was observed between BMI and Emmetropia, however no statistically significant correlation between BMI and Hypermetropia and Astigmatism was found in our study. The study concluded that myopia was the most prevalent refractive error in students in the identified university in north India followed by prevalence of emmetropia, hypermetropia and astigmatism respectively. A significant percentage of respondents had positive family history of myopia. Positive correlation was seen between axial length with myopia. No statistically significant correlations were observed of anthropometric indicators with Hypermetropia and Astigmatism.
