Ultrasonic transmission holography of the eye.

Ocular ultrasonic transmission holography of the eye using equipment capable of real-time imaging has not previously been described. A method using pulsed ultrasound focused on an air/liquid interface is used to demonstate normal ocular structures including lens, optic nerve, and sclera. Intraocular foreign bodies imaged include radiopaque and nonradiopaque materials. A limit of resolution of at lease 1 mm. is demonstrated.
