title: Ultrasonic investigation of the eye with a new contact method and with three different real-time presentations.
abstract: The ultrasound examination was carried out by means of a crystal with a 40 degrees sector scan, which was pressed either against the eyelid or directly against the sclera. The real-time display was obtained by either A-mode, B-mode or combined A/B-mode scanning. In clinical applications, both the resolution capacity and the sensitivity of the device were good. A-mode scanning gave the greatest accuracy in amplitude measurement, while the A/B-mode yielded the most concrete topographic picture of the target.
