To compare the differences in ocular biometric data with regard to gender
Seventy-two eyes from 38 healthy subjects (mean age = 21.4 ± 2.7 years, range: 18 to 31 years) including 19 males (mean age = 22.5 ± 2.6 years) and 19 females (mean age = 20.3 ± 2.5 years) were recruited. Anterior chamber depth (ACD) and axial length (AL) were measured with IOL Master TM (Carl Zeiss Meditec, Jena, Germany). ACD was defined as the length between the center of anterior surface of cornea and the center of anterior lens surface. Angle lambda (kappa), distance from central pupillary eccentricity to thinnest corneal thickness, corneal curvature(CR), corneal power(CP), central corneal thickness(CCT) were measured with pachymetry with a dual scheimpflug imaging system GalileiTM (Ziemer Ophthalmic Systems, Port, Switzerland ). The statistical significance of the gender differences between measurements was evaluated by Student’s t-test.
The mean ACD was 3.77 ± 0.32 mm for males and 3.65 ± 0.25 mm for females. Males had significantly deeper ACD than females (p = 0.049). The mean angle lambda, AL and CCT were 3.15 ± 1.60 °, 25.31 ± 1.59 mm, 552.01 ± 30.05 μm for males and 3.86 ± 1.58 °, 24.79 ± 1.15 mm, 551.81 ± 20.23 μm for females, respectively. Males had significantly larger angle lambda than females (p = 0.028). There was no statistically significant difference in the AL and distance from central pupillary eccentricity to thinnest corneal thickness in gender comparison, but there are tendency associated with differences gender (p = 0.056, p = 0.054). There was no statistically significant difference in mean CR, CP and CCT between males and females.
Both ACD and angle lambda had statistically significant difference with gender. And, AL and distance from central pupillary eccentricity to thinnest corneal thickness were tendency associated with gender difference. However, gender did not show any statistically significant effect on cornea as CR, CP and CCT. Therefore, consider to gender would be an important factor to ocular biometric examinations for refractive and cataract surgeries.
