A Comparative Study of OCT Findings in Low and High Myopia

Abstract

oMyopia or short sightedness is the most common eye disease, responsible for nearly 33 % of defective vision. Myopia is increasing globally, with the most rise in frequency in the young generations in East and Southeast Asia. It causes a huge burden on countries economy due to macular and retinal complications. Myopia is a spherical refractive error in which the point of conjugate focus in the retina is displaced anteriorly in front of the eye, when no accommodation is taking place. Another definition is the refractive condition where parallel light rays originating from an object at optical infinity are focused by the eye in front of the retina through relaxed accommodation. The most common presentation is blurred distance vision, so it is called "nearsightedness." We classified myopia into 2 groups : A) Non Pathological or Simple myope with refraction <-6SD B) Pathological myope groupe with refraction > -6SD. There are many risk factors that may increase the development of myopia of which like positive family history, appearance of myopia using retinoscopy in infants with no cyclopegic effect, emmetropic children with refractive error +0.50 D, accommodation power is decreased or near point esophoria, excessive time spent on near work on a regular basis, when corneal curvature is
