摘 要:目的采用眼前段光学相干断层扫描仪(AS—OCT)测量健康人的眼前段各参数,并分析参数间的关系以及年龄对其的影响。方法采用AS.OCT扫描211例健康人(211只眼)眼前段结构,并测量前房深度(ACD)、前房横径(ACHD)、解剖前房深度(AACD)、晶状体厚度(LT)、睫状体带长度(CBL)、晶状体位置(LP)和虹膜厚度(IT)。对各参数进行性别间的比较,并分析这些参数之间的关系和受年龄的影响。结果男性的ACD、ACHD、AACD、CBL、IT及LP均比女性大[ACD:(2.87±0.38)mm比(2.66±0.40)mm;ACHD:(11.73±0.43)mm比(11.53±0.36)mm;AACD:(3.09±0.19)mm比(3.00±0.19)mm;CBL:(0.20±0.09)mm比(0.17±0.09)mm;IT:(0.36±0.08)mm比(O.34±0.08)mm;LP:(5.11±0.26)mm比(4.91±0.28)mm;均P〈0.05],LT性别差异无统计学意义(P=0.955)。AACD、IT、LP和CBL与年龄均无相关(均P〉0.05);ACHD与年龄呈负相关(r-0.148,P=0.032);LT与年龄呈正相关(r=0.646,P=0.000);LT与ACD呈负相关(r=-0.714,P=0.000)。回归分析表明,LT的增加对LP无影响(P〉0.05)。结论女性的眼前段结构比男性窄。随年龄增加ACD的变浅是LT增加所致;随年龄以及LT的增加,健康人LP不会发生改变。Objective To analyze the relationship among parameters of healthy human eye anterior segment structure detected by anterior segment optical coherence tomography (AS-OCT), and to explore the effect of age on these parameters. Methods AS-OCT was performed in 211 healthy people(211 eyes) to measure the parameters of anterior segment structure, including anterior chamber depth (ACD) , anterior chamber horizontal diameter (ACHD) , anatomy anterior chamber depth (AACD) , lens thickness (LT) , ciliary band length (CBL) , lens position (LP) and iris thickness (IT). These parameters were compared between men and women. Relationship among the parameters was analyzed, and effect of age on anterior segment structure biometric values was evaluated. Results The values of ACD, ACHD, AACD, CBL, IT and LP were significantly higher in male than those in female[ACD: (2.87±0.38) mm vs (2.66±0.40) mm; ACHD : ( 11.73±0.43 ) mm vs ( 11.53±0.36) mm; AACD : ( 3.09±0,19) mm vs ( 3.00±0.19 ) mm; CBL: (0.20± 0.09) mm vs (0.17±0.09) mm;IT: (0.36±0.08) mm vs (0.34±0.08) ram; LP: (5.11±0.26) mm vs (4.91± 0.28) mm; all P〈0.05]. The value of LT was not significantly different between men and women (P=0.955). Age had no significant effect on AACD, IT, LP and CBL (all P〉0.05). ACHD was negatively correlated with age (r=-0.148, P=0.032). LT was positively correlated with age (r=0.646, P=0.000). LT was negatively correlated with ACD (r=-0.714, P=0.000). LT had no significant effect on LP using regression analysis, Conclusions The anterior segments biometrie structure of female is narrower than that of male. With aging, the narrowing of ACD is resulted from LT increment. And LP of healthy eyes does not change with aging and LT increment.
