In many cases, your ophthalmologist may be able to detect Stargardt disease by examining your retina and macula. These parts of the eye often develop yellowish flecks that are deposits of a fatty byproduct of normal cell activity, called lipofuscin, which accumulates abnormally in people with Stargardt disease.
A test called fluorescein angiography or optical coherence tomography (OCT) may also be recommended to obtain more detailed images of your retina. In addition, it may be necessary to measure how the retina responds to light with electrodiagnostic tests such as an electroretinogram (ERG) or multifocal ERG.
