Abstract

Objectives: Evaluation of the influence of anisometropia on visual function 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 was no difference in distance vision without glasses of the group of patients with anisometropia < 1D and the group of patients with anisometropia > 1D. However, the group of patients with anisometropia >1D had lower maximum corrected visual acuity than the group of patients without anisometropia <1D. 18% of patients showed abnormality when maximally adjusted. The prevalence of amblyopia did not differ between men and women. However, there is a difference between age groups: Primary school age has the highest rate of amblyopia. The rate of amblyopia in the group with 1 correct eye is much higher than in the other groups. There was a difference in the rate of amblyopia between the groups with refractive error < 1D and difference > 1D. There are 6 patients indicated for blindfold treatment (6%). All patients with accompanying indications were to treat amblyopia, accounting for 33.33% of total amblyopia patients.
