We measured the anterior chamber depth in 6 eyes of 6 healthy persons in the third decade using an ultrasound biomicroscope (UBM). We tried to obtain a better reproducibility through the addition of a three-dimensional parameter by marking the anatomical landmarks during rotation of the eyeglobe. The UBM image of the anterior chamber was converted into a three-dimensional one by a computer-aided design method to determine the reference point for measurement. The coefficient of variation of anterior chamber depth repeated on two days averaged 0.24% under mydriasis and 0.42% without mydriasis. There was no significant day-to-day difference. Determination of anatomical landmarks thus resulted in better reproducibility in anterior chamber depth measurement using an UBM.
