Abstract:
AlM: To explore a formula between the diopter , cornea diopter ( CD ) , anteriou chamber depth ( ACD ) , lens thickness ( LENS ) , vitreous depth ( VlTR ) , and ocular axis longitude ( AL ) of high school students in certain middle school, and to predict the diopter with the biometry data of refractive factors on the students. METHODS: The related ocular examinations were performed to 364 eyes of 182 high school students in certain middle school by cluster sampling method. Optometry was for diopter and A-ultrasonic biometry was for ACD, LENS, VlTR, and AL. The data were analyzed with SPSS to sum up a poly-variation liner regression formula that can express their quantitative relationship.RESULTS: A poly-variation liner regression was got. The formula was D=69. 750-0. 724×CD-0. 630×ACD-2. 207× LENS-1. 728×VlTR (r=0. 87).CONCLUSlON: The diopter of high school students seems able to be predicted through biometric data of CD, ACD, LENS and VlTR.
