Eye and Orbit Ultrasound
Alternate Names : Echoencephalogram - Eye
Definition
In this test, the eye is examined by ultrasound. The ultrasound uses high frequency sound waves that are emitted and received by a transducer (a hand-held instrument), and the sound waves penetrate the body. Based on the waves recorded, it is possible to determine if the structures being examined are functioning properly.
An echoencephalogram can also be used to examine the cerebral structures (for example, in checking for hydrocephalus), although it is more commonly used for eye disorders.

Why is the Test Performed?
The ultrasound helps evaluate the farthest part of the eyeball when there are cataracts. The test may help diagnose retinal detachment or other disorders and evaluate orbital lesions and intraocular lesions.
