Abstract

Background: Myopia is most prevalent type of refraction error. In some Asian countries, the prevalence of myopia can be 80 - 90% in the population aged 17 - 18.

Aim: To analyze the correlation between ocular biometric indices and refraction status in Vietnamese young myopes.

Methods: A prospective cross - section study was conducted in young myopes. Data on axial length, central cornea thickness, corneal topography & anterior chamber depth and spherical equivalent were collected. Independent Sample T Test and ANOVA test were used to compare between groups. The correlations between ocular biometry and myopic spherical equivalent refraction were examined by Pearson Correlation with the level of significance p < 0.05.

Results: Totally, 418 eyes from 209 patients were recruited. The average axial length, central cornea thickness, cornea refraction & anterior chamber depth were 25.68 ± 1.09 mm, 539.78 ± 32.665 µm, 43.16 ± 1.369 D, 3.30 ± 0.243 mm, respectively. The correlation between axial length and spherical equivalent refraction (SER) was high (r = - 0.742, p < 0.0001) while those between central cornea thickness and cornea refraction were negligible (r = - 0.107, p = 0.029; r = -0.123, p = 0.012; respectively). There was no correlation between anterior chamber depth and spherical equivalent refraction (r = 0.019, p = 0.697).

Conclusion: Among ocular biometric indices, axial length was significantly correlated with spherical equivalent of young adult patients.

Keywords: Anterior chamber depth; Axial length; Central cornea thickness; Cornea refraction; Myopia; Spherical equivalent refraction.
