Comparison of accommodative facility and vergence facility with and without myopia

Abstract

To compare accommodation facility and vergence facility in eyes with myopia and emmetropia.It was a hospital-based comparative study conducted in the Outpatient Department of Ophthalmology. Accommodative and vergence facility measurements were taken with accommodative and vergence flippers.This study was done on 50 subjects, age group between 18-30 Years and it was approved by the IRB committee. This study has done to compare the values of accommodative facility and vergence facility between myopic emmetropic patients. The accommodative facility was measured using accommodative flippers. It was done both monocularly and binocularly for each subject at 3m and 40cm. Vergence facility was measured using vergence flippers. It was confirmed that Accommodative facility [Distance and Near] in right eye, left eye, and botheye was observed as significantly lesser in Myopic patients than Emmetropia. Also, the Vergence facility wasobserved as significantly lesser in Myopic patients than the Emmetropic patients.A reduced accommodative facility and vergence facility was found in myopes in comparison to emmetropia. At both distance and near, the mean facility was less for myopic eyes in comparison with emmetropic eyes.
