Stargardt Disease Diagnosis
Your ophthalmologist will dilate (widen) your eye’s pupils to look at your retina. People with Stargardt disease have yellowish flecks called lipofuscin in and under the macula. Sometimes these flecks extend outward in a ring. Lipofuscin are fat deposits from normal cell activity. These deposits build up more in people with Stargardt disease than in other people.
A test called fluorescein angiography may be used. In this test, a dye is injected into your arm. The dye is photographed as it circulates through the retina’s blood vessels. In people with Stargardt disease, the photos show a dark area within tissue of the retina. This helps the ophthalmologist diagnose Stargardt disease.
Genetic testing is now available to precisely diagnose what type of macular degeneration a patient has. This is the surest way to know the genetic basis for your condition.
