Relationship between refractive error and influencing factors in Children / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

AIM: To evaluate the relationship between axial length ( AL ) , corneal and lens refractive power, and the refractive error in children. METHODS:Totally 44 children 88 eyes with refractive error who underwent retinoscopy with cycloplegia, to be measured spherical equivalent refractive error. Axial length was measured by a noncontact optical biometry ( ZEISS IOL-Master) , and corneal K and anterior chamber depth ( ACD) were also measured by the same machine. The refractive power of the lens was calculated by using the SRK formula. The patients were divided into 3 groups, myopia (SE+0. 50D) and emmetropia ( 0 to + 0. 50D ). Linear Correlation and Regression were used to evaluate the correlation among the optical parameters. RESULTS:Totally 44 subjects, 88 eyes, average 9. 04±2.39 years, spherical equivalent (SE) -3. 50D to +8. 75D. Hyperopic AL was shorter than the other two groups ( P CONCLUSION:As the children's growing up, SE trends to myopia, and AL becomes longer, and lens power is stronger.
