Comparative ultrasound oculometry. TAU-measurements of thirty eyes with three standard equipments.
Ultrasound oculometry (A mode) was performed in 30 eyes with three different standard equipments and great effort was made to make the three sets of measurements comparable. In spite of careful calibration procedures significant inter-equipment differences were found: anterior chamber depths and lens thicknesses showed the greatest discrepancies. These findings should be kept in mind when oculometric results of different authors are compared. A standardized eye-like phantom is desirable as a common reference for all who work in ultrasonic oculometry.
