The interaction between axial length and corneal radius of curvature (CRC) has played a major role in the compensatory adjustments of the optical components of the eye towards attaining emmetropic state [8]. Piero DP, Camps VJ, Caravaca-Arens E, de Fez D, Blanes-Momp FJ. At least three readings were taken and the average calculated as the measured axial length. The refractive state of the eye is determined by refractive components (corneal power, lens power, anterior chamber depth, and axial length) which are interdependent rather than independent variables, and that the eye grows during the early years in life in such a manner that the refractive state tends towards emmetropia [1, 2]. One-way analysis of variance (ANOVA) was used to compare the mean axial length-corneal radius of curvature and axial length-corneal radius of curvature ratio across the refractive status groups. Internet Explorer). The probe was sterilized with 70% alcohol and allowed to air-dry.

Intraocular pressure and related systemic and ocular biometric factors in a population-based study in Japan: the Kumejima study. [13] also reported that eyes with more myopic refractive error tended to have greater axial length. Would you like email updates of new search results? The AL/CRC ratio for each subject was obtained by dividing the axial length by the corneal radius of curvature. Unauthorized use of these marks is strictly prohibited. Corneal Topography - PubMed Trans Am Ophthalmol Soc. government site. Ocular determinants of refractive error and its age-and sex-related variations in the Chinese American eye study. 16 0 obj 1). 2010;117:41723. and transmitted securely. 2020 Jan;43(1):67-79. The dioptric power, and the radius of curvature at a particular point, are read by comparing the amount of magnification needed to match the photographed rings to a standard set of rings on the comparator screen.
