Resumen
REY-RODRIGUEZ, Diana V. et al. Differences in the biometric components of the eye between men and women. Rev. mex. oftalmol [online]. 2022, vol.96, n.4, pp.155-161. Epub 30-Ene-2023. ISSN 2604-1227. https://doi.org/10.24875/rmo.m22000238.
Purpose:
To evaluate the differences in ocular biometric components such as axial length, anterior chamber depth, lens thickness, corneal curvature and corneal thickness between men and women.
Method:
Cross-sectional analytical observational study in 106 university students aged 18-36 years. All subjects underwent refraction under cycloplegia and assessed through autorefractometry. The refractive error was measured after the application of 1% cyclopentolate. For the identification of biometric components, an assessment was carried out with the Aladdin equipment (Topcon Corporation, Equipos Oftalmológicos Colombia).
Results:
Of the 106 participants, 71.7% (76) corresponded to the female sex, aged between 18 to 36 years. In women, the mean axial length was 23.3 ± 0.88 mm and in men 23.9 ± 0.99 mm. The anterior chamber depth was 3.5 ± 0.26 mm in women and 3.6 ± 0.22 mm in men. The lens thickness in women was 3.47 ± 0.22 thickness in womenm and 3.53 ± 0.20 μm in men. Corneal thickness in women was 538.65 ± 0.36 μm and in men it was 542.43 ± 32.73 μm. The mean keratometry in women was 43.54 ± 1.35 D and in men 42.76 ± 1.79 D. There were statistically significant differences between corneal curvature (-0.78 D; for men p = 0.01 and for women p = 0.003) and axial length (0.63 mm; for men p = 0.02 and for women p = 0.04).
Conclusions:
There are differences in corneal curvature of up to 0.75 D, being more curved in women and a larger size of the eyeball in men, anatomical characteristics that intervene in the prevalence of refractive errors.
