The Relationship between Axial Length, Refractive Power and Foveal Thickness Measured by OCT in Koreans

ABSTRACT

PURPOSE: To evaluate the relationship between foveal thickness and axial length and refractive power in healthy Koreans. METHODS: Ninety-eight healthy eyes were studied. The axial length was measured using A-scan (Paradigm mode p45, Kent, U.K.) and refractive power using automatic refractor Automatic refractor(HARK-599, Carl Zeiss, USA). The subjects were divided into 2 groups based on axial length (>or=25 mm and -6.0D). The foveal thickness was measured using OCT 3000 (Optical Coherence Tomography, Carl Zeiss, USA) and the statistical relationship between the 2 groups was analyzed by independent t-test. RESULTS: There was no statistically significant difference found in foveal thickness according to axial length between the two groups (p>0.05) nor according to refractive power (p>0.05). CONCLUSIONS: When eyes with pathologic myopia were excluded, The axial length and refractive power of the eyes had no relation to foveal thickness measured by OCT.
