Ways In Which Stargardt Disease Is Diagnosed

Color Testing

Color testing is especially useful for patients who may be experiencing the changes to their color vision that frequently occur in the later stages of Stargardt disease. The testing can also be beneficial as a screening tool. Plate tests are widely used to test color vision, and they involve the patient identifying a colored symbol embedded in a background. Other forms of plate testing ask the patient to choose which color in a series of four colors is most similar to a specific color, and patients could also be asked to determine which circle most closely matches the shade of a gray rectangle. Arrangement tests and lantern tests may be used in conjunction with plate testing, and some healthcare providers may opt to administer testing with the use of anomaloscopes.
