At an eye exam, your physician can usually look through your pupil to see the back of the eye. However, changes in the eye sometimes can prevent a view into the back of the eye, or the physician may not be able to accurately measure the changes. When these situations occur, an ultrasound of the eyeball can be very helpful.
Ultrasound images and measurements help your physician diagnose changes in an eye and accurately measure eye structures for monitoring and treatment. An ultrasound of the eye involves numbing the eye and placing a small probe that admits sound waves on the numbed eye. Patients feel a small vibration, though it is not painful. The reflection of these sound waves are then measured and processed to give an image of the structures in the back of the eye as well as accurate measurements of the changes. An eye ultrasound usually takes about one hour.
