摘 要：Objective:The purpose of this study is to investigate the ocular dimensions in Chinese adolescents with keratoconus(KC).Methods:One hundred and six KC eyes of 53(42 boys and11 girls)KC adolescents(age 15.5±1.7 years,range 11 to18)were involved in this retrospective *** eye with more severe KC(Severe Group)of each patient was compared to their less affected eye(Mild Group).Optical axial length(OAL)was measured by optical coherence biometry(IOL-master).Central corneal thickness,anterior chamber depth(ACD),flat keratometry value,steep keratometry value,and maximum keratometry value were assessed with an anterior segment analyzer(Pentacam HR).Anterior segment length(ASL)was manually measured from the 25 scheimp flug images captured by the Pentacam HR with the mean value *** posterior segment length(PSL)was calculated with the formulaPSL=OALASL.Results:The mean ACD,OAL,ASL,and PSL values of the Severe Group were(3.51±0.32)mm,(24.76±1.24)mm,(4.01±0.30)mm and(20.76±1.15)*** those of the Mild Group were(3.36±0.29)mm,(24.97±1.40)mm,(3.94±0.35)mm and(21.03±1.31)*** Severe Group has significantly higher ACD(P0.001)value but lower OAL(P0.05)and PSL(P0.001)values when compared to those of the Mild ***:For adolescent KC,the more severe keratoconic eyes may be characterized by deeper ACD but shorter OAL and PSL,when compared to the less affected ones.
