The Arden Screening Test
The Arden Screening Test is a simplified
version of a more complex test developed by Dr. Arden at Moorfield’s Eye
Hospital in England. Glaucoma research has shown that glaucoma affects the
color vision (especially blues and yellows) before it can be identified with
an eye exam or visual
field test. Dr. Arden developed a special color vision test to help
identify and treat glaucoma patients as early as possible.
Scott Brodie, MD, an eye surgeon from New York, designed a simplified version
of this color test that can be completed in just minutes. For the Arden
Screening Test, the patient is seated in front of a computer screen and a
series of colored circles are displayed that have a break, or missing area on
contrasting backgrounds. While looking straight ahead, the patient identifies
the location of the break with her peripheral vision. As the test progresses,
the contrast between the circle and the background slowly decreases until
patient can no longer identify the break.
This test is very important when determining whether glaucoma treatment is
appropriate. St. Luke’s Cataract & Laser Institute is one of the few
facilities in the country to offer the Arden Screening Test. This test enables
us to separate patients who have elevated pressures or other suspect glaucoma
signs that are normal from those who truly have the disease and require
treatment. |
