Examination of the eye by means of an ultrasonic echoscope can provide the clinician with information unobtainable in any other way. Pulsed ultrasound is directed into the orbital structures and the echoes received are used to build up a horizontal cross‐sectional picture on a storage screen. A series of more than 80 patients with a variety of conditions has been examined in an attempt to establish a characteristic pattern for the normal eye and for common types of abnormality. At the present stage of development, the CAL ophthaimological echoscope produces high quality repeatable echograms. We feel confident that we can estimate accurately the size of a globe and be reasonably sure that no detachment or large tumour is present in an eye with an opaque lens. We are not yet confident of accurately diagnosing retrobulbar lesions in all cases. The echoscope is providing increasingly valuable clinical information as more patients are examined.
