  1. 1.

    Using Santesonic SSD-121, distinct B-mode images can be displayed easily and constantly. Specific skill of the examiner is not required.

  2. 2.

    Of intraocular membranous lesions, kinetic analysis in real time can be done. The shape, extent, mobility and connection to the posterior wall are clearly shown. Of orbital space-occupying lesions, the shape, size as well as consistency are shown.

  3. 3.

    Minute observation after images freezing is available. And the equipment can be connected to a video-recorder and hard copy devices.

  4. 4.

    Measurement of the size of ocular and orbital lesions, as well as of axial length can be done with incorporated electronic calipers. Distance in two directions on a frozen image can be measured at the same time and the result is displayed on the monitor.

  5. 5.

    In A-mode display the area of displaying is very small and the top of spikes is prone to be rectangular. Further improvement is required for precise ultrasonic tissue characterization.
