Abstract

Objective: Evaluate the pattern of refractive errors in children and assess variables associated with severity of refractive errors from 2021 to 2022. Methods: descriptive cross-sectional study was performed on 162 children (324 eyes total) aged 6 to 15 years old, diagnosed with refractive errors at the Vietnam National Institute of Ophthalmology (VNIO) from 9/2021 to 7/2022. Results: 50% of participants presented to VNIO due to reduced visual acuity. Myopia accounted for 66,9% of the subjects, followed by hyperopia at 26,3% and mixed astigmatism at 2,6%. 14,2% of study participants suffer from amblyopia as a result of refractive errors, while 18% were determined to have anisometropia. Anterior chamber depth and axial length of myopic eyes are statistically significantly higher than that of hyperopic cases. Conclusion: Myopia is demonstrated as the most prevalent refractive error, followed by hyperopia and mixed astigmatism, respectively. A statistically significant difference in anterior chamber depth and axial length between myopia and hyperopia was observed.
