Evaluation of macular and retinal nerve fibre layer thickness in unilateral amblyopic patients by using optical coherence tomography

Abstract

Aim: To evaluate the macular and the retinal nerve fiber layer thickness in patients with unilateral amblyopia. Design: Prospective observational study. Material and Methods: 188 eyes of 94 patients with unilateral amblyopia diagnosed by difference of at least two lines between the normal and amblyopic eye on Snellen visual acuity charts was included. Statistical analysis: Unpaired sample t-test.Results: Majority of the cases was seen in age group 21-30 years with male preponderance. The average macular thickness was 271.4µm for normal eye versus 278.0µm for amblyopic eye, values by unpaired t-test was t-value=3.169, p=0.002
