摘      要：AIM:To investigate the association of axial length(AL)and ocular factors on AL ***:A retrospective chart review of patients who underwent two or more AL examinations for more than two *** 4 groups were divided according to initial AL(24 mm,24-26 mm,26-28 mm,≥28 mm).Initial fundus photograph was used to find risk factors associated AL ***:The mean age of the patients was 47.21±7.79 *** remained almost unchanged in the groups with AL24 mm and 24≤AL26 *** the contrary,AL increased by 0.011 mm/y in the group with 26≤AL28 mm and 0.035 mm/y in the group with AL≥28 mm(P0.001).In high myopia,AL elongation increased in eye with longer AL(r=0.003,P=0.024),female gender(r=0.014,P=0.019),eye with larger peripapillary chorioretinal atrophic area(r=0.002,P=0.019),and smaller vascular arcade angle(r=-0.004,P=0.006).The risk of elongation 0.03 mm/y in high myopia was increased in female gender(P=0.040),and gradually increased in eye with large peripapillary chorioretinal atrophy area(P0.01).CONCLUSION:AL elongate significantly in the eye with longer AL,female gender,and the eye with larger atrophic area and smaller arcade angle on fundus photography.
