EVALUATION OF MYOPIA AND ITS CORRELATION WITH CORNEAL CURVATURE AND AXIAL LENGTH OF EYEBALL IN TERTIARY CENTER

Introduction: Refractive errors are a common cause of visual disorders, of which myopia is the second most common. Myopia is also known as shortsightedness. It is a condition occurring as a result of increased global axial length or increased refractive power of anterior segment, with the former being more important.

Aim:  To evaluate the myopia and its correlation with axial length and corneal curvature .

Methods: A cross-sectional study conducted from July 2022 to December 2023 on 100 Cases of Myopia attending OPD in Department of Opthalmology, JNU Medical College, Jaipur. Refraction was measured as the spherical equivalent (SE).

Results: In present study, the patients were divided into three groups: mild myopia (≤−0.50D and >−3.00D), moderate myopia (≤−3.00D and >−6.00D), and high myopia (≤−6.00D), according to Spherical Equivalent (SE).In present study AL showed statistically significant differences among the three groups and AL increases with increase in myopia grade. In present study corneal curvature showed no statistically significant differences among the three groups i.e. corneal curvature is not statistically significantly associated with grades of myopia. In present study AL/CR showed statistically significant differences among the three groups and AL/CR increases with increase in myopia grade.

Conclusions: The present study concluded that that AL and AL/CR were significantly negatively correlated with SE in myopia patients, and the correlation between AL/CR and SE is higher than that between AL and SE. AL and AL/CR can be used as an alternative refractive status evaluation method for refraction.
