Ocular Ultrasound |
|
Ocular ultrasound uses high-frequency sound waves that travel through the eye. Reflections (echoes) of the sound waves form a picture of the structure of the eye. The precise size of the eye and any abnormalities in structure can be measured.
Why is ultrasound performed? The ultrasound helps evaluate the retina and other structures at the back of the eye when the view to this area is difficult. The test provides valuable information when there is cataract, vitreous hemorrhage, retinal detachment, eye tumor, trauma, or inflammation. This test can help your doctor monitor progress or plan for treatment.
How does the test occur? This test can be performed in the exam chair at the office. Your eye is anesthetized with numbing drops and then the ultrasound wand is gently placed on your eyelid with lubricant. Sound waves emitted from the wand bounce off of structures within (and behind) your eye and return to the machine to create an image. The doctor or technician may ask you to look in various directions. The test takes less than 5 minutes, and then the lubricant is wiped away from your eyelid.
Are there any side effects? To avoid scratching the cornea, do not rub the anesthetized eye until the anesthetic wears off (about 15 minutes). There are no other risks. |
