Retinal and Glaucoma Diagnostics
PROTECTING YOUR VISION
Testing And Treatment
There is no one test that may be used to detect all forms of retinal disease and
glaucoma. For that reason, the Clearview Institute uses a variety of retinal and
glaucoma procedures - including an eye pressure check, visual field test and optical
nerve evaluation - that incorporate the latest state of the art technology. These
procedures accurately assess progression and ensure we take every possible precaution
to ensure our patients do not lose their vision.
Optical Coherence Tomography
In this procedure, we extract a cross-section of the eye using a non-harmful, no-touch
laser. We combine two different tomographies to image the eye from the front to
back to determine the type of glaucoma the patient might have. We obtain an image
of the optical nerve down to a level of microns and obtain an image of the macula,
the area responsible for fine vision. In addition, we are non-invasively able to
detect swelling, bleeding and other problems as well as look at the thickness of
the cornea.
Two separate pieces of equipment are deployed for this procedure - the Visante™
OCT and the Cirrus™ High Definition OCT.
Ocular Response Analysis (ORA)
ORA enables us to examine the biomechanics of the cornea to gauge its rigidity or
bounciness. For instance, if the cornea is soft, it may be more susceptible for
damage. ORA is an excellent screening tool for patients who are at risk for refractive
surgery.
ORA is performed using a Reichert Response Analyzer, manufactured by Reichert Ophthalmic.
Visual Field Testing
It is important to assess whether or not a patient's side vision has been lost
in order to follow and monitor ocular diseases such as glaucoma, macular degeneration
and diabetic retinopathy.
The Clearview Institute uses a Humphrey® Field Analyzer (HFA) to test your side
vision and your central vision. The HFA's video monitoring system makes it easy
to track the patient's eye and its gaze monitor provides a real time evaluation
of the patient's eye fixation.
Early Glaucoma Detection
The Clearview Institute uses a GDx™VCC, the latest diagnostic tool used for detecting
glaucoma in its early stages. This technology uses a laser ophthalmoscope to take
a picture of the back of the eye in order to evaluate the nerve fiber layer directly
and objectively. The GDx™VCC is an easy test to administer with no dilation required.
And test results are produced in minutes.
