目的：探讨A超、超声生物显微镜(ultrasonic biological microscope，UBM)及眼前节分析仪(Pentacam)测量原发性急性闭角型青光眼(acute primary angle-closure glaucoma，APACG)中央前房深度(central anterior chamber depth，ACD)的研究。
方法：选取APACG患者35例35眼，采用A超、UBM及Pentacam测量其中央ACD。
结果：A超、UBM及Pentacam测量APACG的ACD值分别为1.5633±0.2089、1.5783±0.2067、1.6275±0.2296mm，结果经levene方差齐性检验方差齐，LSD-t方法进行两组间多重比较，差异具有统计学意义(F=4.074，P=0.026)。A超与UBM、A超与Pentacam、UBM与Pentacam的ACD比较，差异具有统计学意义(P=0.032、0.023、0.012)。应用Bland-Altman分析显示，三种方法相互间一致性较差。
结论：三种方法测得APACG的ACD，Pentacam测得的结果最大，其次是UBM，A超测得的结果最小。在临床上A超、UBM及Pentacam检查具有各自不同的优势，可以相互弥补，不能取代，在临床工作中应把这三者优势结合起来，综合分析，才能得出更准确的结果。

[Abstract]
AIM: To investigate the measurement of central anterior chamber depth(ACD)in patients with acute primary angle-closure glaucoma(APACG)with A-scan ultrasound, Pentacam and ultrasonic biological microscope(UBM).
METHODS: Thirty-five patients(35 eyes)with APACG were selected, of whom central ACD were measured with A-scan ultrasound, Pentacam and UBM.
RESULTS: The measurement values of ACD with A-scan ultrasound, UBM and Pentacam were 1.5633±0.2089, 1.5783±0.2067, 1.6275±0.2296mm, which was equal variance tested by the homogeneity of variance,and was significant different by multiple comparision(F=4.074, P=0.026). The difference of ACD between the two groups of A-scan ultrasound and UBM, A-scan ultrasound and Pentacam, UBM and Pentacam were statistically significant(P=0.032, 0.023, 0.012). Altman-Bland analysis showed that the three methods were not consistent with each other.
CONCLUSION: The ACD value of the APACG with the three methods is the largest using Pentacam, followed by UBM and A-scan ultrasound. In clinical the three methods with different advantages can complement each other, but cannot be replaced. In order to obtain more accurate results, we should combine the advantage and make comprehensive analysis.
