Ultrasound
The ocular
ultrasound is an imaging technique that uses
high-frequency sound waves, similar to sonar, used
in oceanography. Ocular ultrasound is used to
exam the inside of the eye, especially when the
doctor's view is blocked by an opacity like a
damaged
cornea, a thick cataract or a hemorrhage
inside the eye.
The technician will
have you lie down on a table and you will be asked
to close your eyes. A small amount of water-based
jelly will be placed on your eyelid and a transducer
with an eye cup on the end will be placed over the
eye. The transducer is a small probe that sends the
utrasound waves to the area of interest.
During the test, the
technician may ask you to move your eye to different
positions to get different ultrasound angles. You
should continue to keep your eyes closed throughout
the test. The technician will remove the jelly from
your eye or eyes when the test is finished. |
