Abstract

Objectives: Evaluation of anisometropia in students. Subjects and methods: Prospective corelation study, 100 patients with refractive errors in school age from 6-17 years old , examination with anisometropia at Nghe An Eye Hospital from March 2022 to August 2022. Results: There are 79% of patients with anisometropia below 1D; Twenty-one patients (21%) had anisometropia over 1 D. In which anisometropia (1-3D) accounted for 18% and anisometropia multiple (≥3D) accounted for 3%. The rate of anisometropia in patients with 2 eyes with the same refractive error accounted for the highest rate (42.86%). The rate of anisometropia in children with 1 correct vision in the total number of children with refractive error is 42.56%. The rate of myopia (41.93%) is much higher than the rate of hyperopia (19.35%) and the rate of emmetropia (4.83%). There are 11.5% of eyes with good vision from 20/30 and the majority of eyes with visual acuity <20/40 accounted for 70%. The difference in the proportions of the patient's visual acuity levels was statistically significant (P<0.05). There was no difference in the incidence of anisometropia in patients between men, women and age groups.
