Purpose: This study was to analyze refractive error and corneal curvature radius in childhood myopia.
Methods: The average age of 9.92 ± 1.08 years Children 50 people(24 males and 26 females) were evaluated for refractive error with an automatic refractometer, Pentacam was used to measure the corneal curvature radius.
Results: The mean total spherical diopter was -2.43 ± 1.39D and astigmatism diopter was -0.75 ± 0.66D, horizontal radius of curvature was 7.88 ± 0.23mm, vertical radius of curvature was 7.67 ± 0.23mm, corneal astigmatism -1.18 ± 0.56D, diameter was 11.75 ± 0.47mm, eccentricity was 0.55 ± 0.10. There was no significant difference spherical diopter(t=-0.357, p=0.722), corneal astigmatism (t=1.410, p=0.162), eccentricity(t=0.627, p=0.532) in male and female, astigmatic diopter(t=2.097, p=0.039), horizontal radius of curvature(t=2.397, p=0.018), vertical radius of curvature(t=2.685, p=0.009), diameter(t=2.157, p=0.033) were significantly different. There was no significant difference spherical diopter(t=-0.952, p=0.343), astigmatism diopter(t=1.260, p=0.211), horizontal radius of curvature (t=-0.596, p=0.553) vertical radius of curvature(t=-0.495, p=0.621), corneal astigmatism(t=0.662, p=0.509), diameter (t=-0.411, p=0.682), eccentricity (t=0.080, p=0.937) between in male and female.
Conclusions: Male and female were significant different astigmatism diopter, horizontal radius of curvature, vertical radius of curvature, diameter in childhood myopia. There was no significant difference between right eye and left eye.
