UNASSIGNED: In this cross-sectional study, values of ocular biometry parameters, including axial length (AL), anterior chamber depth (ACD), mean corneal curvature (mean K), lens thickness (LT), corneal astigmatism (CA), and white-to-white (WTW) of 818 eyes with cataracts, were measured using the OA-2000 biometry device (Tomey, Nagoya, Japan). The participants were divided into si age subgroups, in 10-year intervals. Finally, the values of the biometry parameters were calculated, and the trend of changes was examined for both age and sex subgroups.
UNASSIGNED: The mean (standard deviation [SD]) of age of the participants was 63.82 (13.25) years. Mean (SD) of biometry parameters were as follows: AL, 23.36 (1.55) mm; ACD, 3.09 (0.40) mm; LT, 4.45 (0.55) mm; mean K, 44.51 (1.72) D; CA, 1.06 (0.94) D; and WTW, 11.81 (0.45) mm. Most of the parameters showed significant age-related changes in the total population. There was an increase in LT (P < 0.001) and mean K (P = 0.001), as well as a decrease in AL (P < 0.001) and ACD (P < 0.001) with age. Moreover, AL had a negative negligible correlation with LT (r = - 0.24; P < 0.001) and mean K (r = - 026; P < 0.001), as well as a weak positive correlation with ACD (r = + 0.44; P < 0.001).
UNASSIGNED: Our study revealed that the mean values of most biometric parameters varied across age and sex subgroups. Moreover, most of the parameters showed significant age-related changes in the total population.
■在这项横断面研究中,眼生物测量参数值,包括轴向长度(AL),前房深度(ACD),平均角膜曲率(平均K),透镜厚度(LT),角膜散光(CA),和白色到白色(WTW)的818眼白内障,使用OA-2000生物测定装置(Tomey,名古屋,日本)。参与者被分为不同年龄的亚组,以10年为间隔。最后,计算生物参数的值,并检查了年龄和性别亚组的变化趋势。
■参与者年龄的平均值(标准偏差[SD])为63.82(13.25)岁。生物参数的平均值(SD)如下:AL,23.36(1.55)mm;ACD,3.09(0.40)mm;LT,4.45(0.55)mm;平均K,44.51(1.72)D;CA,1.06(0.94)D;和WTW,11.81(0.45)毫米。大多数参数显示出总人口中与年龄相关的显着变化。LT(P<0.001)和平均K(P=0.001)增加,以及AL(P<0.001)和ACD(P<0.001)随着年龄的增加而降低。此外,AL与LT(r=-0.24;P<0.001)和平均K(r=-026;P<0.001)呈负相关,可以忽略不计,与ACD呈微弱正相关(r=+0.44;P<0.001)。
■我们的研究表明,大多数生物参数的平均值因年龄和性别亚组而异。此外,大多数参数显示总人口中与年龄相关的显著变化.
