目的 比较A超与超声活体显微镜(UBM)测量白内障患眼前房深度(ACD)值的差异.方法 系列病例研究.对2008年1月至2010年3月在南京鼓楼医院眼科行白内障术前检查的396例患者(480只眼)分别用A超和UBM测量ACD值.按晶状体前皮质光学区域是否混浊分为两组:前皮质无混浊的各型白内障(前皮质无混浊组)433只眼(占90.21％)；皮质性或伴前皮质混浊(前皮质混浊组)的各型白内障47只眼(占9.79％)；前者按UBM的ACD测量值分＜3.0 mm、3.0～3.5 mm、＞3.5mm组.对两种方法的ACD测量值进行配对t检验.结果 前皮质无混浊的各型白内障眼ACD平均测量值:UBM (3.24 ± 0.56) mm,A超(3.14±0.56) mm.平均差异(0.10±0.06)mm,两者差异无统计学意义(t=0.128,P=0.082).其中ACD ＜3.0 mm组平均测量值:UBM(2.61 ±0.26)mm,A超(2.50 ±0.29)mm.平均差异(0.11±0.1O)mm,两者差异有统计学意义(t=0.744,P=0.023)；伴晶状体前皮质混浊的各型白内障眼ACD平均测量值:UBM (2.51 ±0.52) mm,A超(3.84±0.55) mm,平均差异(-1.33 ±0.41)mm,两者差异有统计学意义(t=14.792,P=0.000).结论 光学区域前皮质无混浊的各型白内障眼,A超的ACD平均测量值与UBM相比无明显差异.其中的浅ACD者,两种方法测量值的差异较明显；光学区域前皮质混浊时,A超的测量值远超UBM的ACD值.

Objective To know the difference of measured anterior chamber depth (ACD) in cataract eyes between A-scan and ultrasound biomicroscopy (UBM) measurements.Methods Case series study,the ACD of 396 patients (480 eyes with cataract) came from the Department of Ophthalmology,Nanjing Drum Tower Hospital between January,2008 and March,2010,were measured by A-scan and UBM.Two groups were classified by whether the optical area of anterior cortex was transparent or not:433(90.21％) eyes with transparent anterior cortex and 47 (9.79％) eyes with opacific anterior cortex.The former are classified into 3 groups: ＜ 3.0 mm,3.0-3.5 mm,＞ 3.5 mm,according to the ACD value of UBM.The differences of ACD between A-scan and USB readings was analyzed.Results Theaverage ACD value of cataract eyes with transparent anterior cortex was (3.24 ± 0.56) mm (measured by USB) and (3.14 ± 0.56) mm (measured by A-scan),respectively.There was no significant difference between these two measurements (t =0.128,P =0.082).In eyes withACD ＜ 3.0 wm,the average ACD was (2.61 ±0.26)mm (by UBM) and (2.50 ±0.29)mm (by A-scan),respectively,with a difference of (0.11 ± 0.10) mm.There was a statistical significant difference between these two measurements (t =0.744,P =0.023).The average ACD value of cataract eyes with opacific anterior cortex opacity was (2.51 ± 0.52) mm (by UBM) and (3.84 ±0.55) mm (by A-scan),respectively,with a difference of (-1.33 ± 0.41) mm.There was a significant difference between these two values (t =14.792,P =0.000).Conclusions In cataract eyes with transparent optic area of anterior cortex,there is no significant difference between measured ACD by A-scan and UBM.In eyes with ACD less than 3.0 mm,there is a significant difference between measured value by A-scan and UBM.When the optical area of anterior cortex is opacific,Ascan records are much higher than the ACD value measured by UBM.
