The
anatomy of the eye can be examined with ultrasound. The sound beam
delivered is reflected at interfaces of differing tissue densities
and the reflected beam is received by the transducer. The reflected
sound waves are analyzed to give further information about ocular
structures. The transducer itself may be placed directly on the
eye, after topical anesthesia, or on the eyelid, depending on the
desired procedure. A-scan ultrasound is necessary as part of the
preoperative evaluation for cataract surgery, as the axial length
of the eye must be determined to properly calculate the necessary
intraocular lens power for any given
eye. B-scan ultrasound displays internal anatomy of the eye, allowing
for evaluation of the retina when it is obscured by media opacities,
such as occurs with dense cataract and vitreous hemorrhage. B-scan
ultrasound is also integral in the evaluation of ocular tumors and
a variety of other ocular disorders.

At
Ahalia, we have the latest ultrasound machine, which gives a 3 dimensional
view of ocular structures & thus helps in better reconstruction
of images.
