Abstract: A cross sectional study with a purpose to establish a relationship between the degree of myopia and axial length using A- scan and to determine the changes in axial length in two genders and different age groups.
Methods: 150 eyes of patients were examined for anterior segment using slit lamp biomicroscope.The visual acuity, cycloplegic refraction,retinoscopy, fundoscopy were done for all the selected patients after obtaining an informed consent. The axial lengths that were obtained using A- scan were correlated with the degree of myopia. They were further subclassified on basis of age,sex, familial factors and complications.
Results: Statistical correlation was seen between the axial lengths and degrees of myopia. Subjects having less than -6D constituted 69.9% of the cases. Myopia greater than -6D was associated with degenerative changes. Lower degrees of myopia had good corrected visual acuities. Keywords: Myopia, visual acuity, refraction, axial length, A-scan.
