Ocular Ultrasound

Ocular ultrasound is a technique in which a small ultrasound probe is used to image the eye. Sound waves transmitted from the probe reflect differently through various layers of the eye, thus generating a virtual image. Conditions such as a dense cataract or vitreous hemorrhage can prevent a direct view of the retina. When a view to the back of the eye is not possible, the ultrasound probe can produce an image of the entire eye. Ultrasound can also be used to diagnose and make measurements of a tumor within the eye.
