Abstract:
AIM:To evaluate the correlation between axial lengths and anterior segment parameters using swept-source optical coherence tomography(SS-OCT).METHODS:For the cross-sectional clinical study, a total of 109 adult volunteers with different degrees of myopia recruited from January 1, 2022, to March 31, 2022, at the ophthalmology clinic of the First Affiliated Hospital of Zhengzhou University were included. Participants were divided into 4 groups based on axial length(AL): group A(AL≤24.0mm), group B(24.0mm26.0mm). Anterior segment examinations were performed using SS-OCT, including: central corneal thickness(CCT), lens thickness(LT), anterior chamber depth(ACD), anterior chamber width(ACW), angle opening distance(AOD500), angle recess area(ARA500), trabecular iris space area(TISA500), trabecular iris angle(TIA500), crystalline lens rise(CLR). The relationships between these data and AL, spherical equivalent(SE)were analyzed.RESULTS:There was no difference in the comparison of CCT among the four groups(P>0.05). There were differences in SE, LT, ACD, ACW, AOD500, ARA500, TISA500, TIA500 and CLR among the four groups(all P<0.01). SE and LT were negatively correlated with AL(r=-0.75, -0.41, all P<0.01); ACD, ACW and CLR were positively correlated with AL(r=0.58, 0.45, 0.54, all P<0.01); AOD500, ARA500, TISA500 and TIA500(temporal and nasal side)were positively correlated with AL(all P<0.01). ACD and CLR were negatively correlated with SE(r=-0.21,-0.25, all P<0.01), and LT was positively correlated with SE(r=0.21, P<0.05).CONCLUSION:As AL increases, CCT remains unchanged while the ACD and ACW increase. The position of the crystalline lens moves backward and LT decreases.
