To investigate the mean values and standard deviations according to age, reliability, and correlation between different parameters of anterior chamber measurements using the Pentacam rotating Scheimpflug camera.
Heidelberg IOL and Refractive Surgery Research Group, Department of Ophthalmology, University of Heidelberg, Heidelberg, Germany.
This prospective clinical study comprised 76 healthy volunteers (mean age 46.6 years +/- 16.8 [SD]). Three consecutive measurements were made of only 1 eye and anterior chamber depth (ACD), mean and minimum anterior chamber angle (ACA), and anterior chamber volume (ACV) were evaluated.
Mean ACD was 2.93 +/- 0.36 mm, mean ACA was 34.81 +/- 5.05 degrees, minimum ACA was 29.99 +/- 5.53 degrees, and mean ACV was 160.3 +/- 36.81 mm3. Increasing age was associated with reduced ACD and ACV; however, mean and minimum ACAs were lowest in patients aged 40 to 59 years. Excellent correlation was found between ACD and ACV (R = 0.92). Anterior chamber depth and mean ACA correlated only moderately (R = 0.65). The correlation coefficient between ACD and minimum ACA was smaller (R = 0.58). There was no correlation between ACV and ACA (R = 0.37). Minor standard deviations were noted (ACD 0.02 +/- 0.02 mm, mean ACA 1.12 +/- 0.94 degrees, minimum ACA 2.04 +/- 2.67 degrees, and ACV 2.48 +/- 1.65 mm3).
Using the Pentacam, it was possible to examine different parameters of the anterior chamber within a short period and with good reliability. The evaluation of the ACA in different positions can help to classify the potential risk for angle-closure glaucoma.
使用Pentacam旋转式Scheimpflug相机，根据年龄、可靠性以及前房测量不同参数之间的相关性，研究其平均值和标准差。

这项前瞻性临床研究纳入了76名健康志愿者（平均年龄46.6岁±16.8[标准差]）。仅对1只眼睛进行连续3次测量，并评估前房深度（ACD）、平均和最小前房角（ACA）以及前房容积（ACV）。
平均ACD为2.93±0.36mm，平均ACA为34.81±5.05度，最小ACA为29.99±5.53度，平均ACV为160.3±36.81mm³。年龄增加与ACD和ACV降低相关；然而，40至59岁患者的平均和最小ACA最低。ACD与ACV之间存在极好的相关性（R = 0.92）。前房深度与平均ACA仅呈中度相关（R = 0.65）。ACD与最小ACA之间的相关系数较小（R = 0.58）。ACV与ACA之间无相关性（R = 0.37）。观察到较小的标准差（ACD为0.02±0.02mm，平均ACA为1.12±0.94度，最小ACA为2.04±2.67度，ACV为2.48±1.65mm³）。
使用Pentacam，可以在短时间内且以良好的可靠性检查前房的不同参数。对不同位置ACA的评估有助于对闭角型青光眼的潜在风险进行分类。
