Read our Macular Degeneration research guide →Researchers are testing a new vision test called the Multi-Luminance Shape Discrimination Test (MLSDT) to see if it can accurately measure how well people with certain retinal diseases can see. The test uses 9 different shapes shown at different brightness levels. This study wants to confirm that the test is reliable and works well for patients with Stargardt disease, geographic atrophy, or macular degeneration.
Current vision tests may not capture all the ways that retinal diseases affect how people see in real life. Researchers need a better, standardized test that can accurately measure vision problems in patients with these conditions, which could help doctors track disease progress and evaluate new treatments more effectively.

You will visit the study clinic to have your vision tested using both traditional eye charts and the new Multi-Luminance Shape Discrimination Test. The researchers will look at how well you can identify shapes displayed at different brightness levels and compare your results to your standard vision measurements. The study enrolls 30 people total across three groups: people with normal vision, people with moderate vision loss, and people with severe vision loss from retinal disease.
