Eye tests and vision in macular dystrophy

This study uses a special vision test called microperimetry to track how well the macula (the center of the retina) works in people with certain eye conditions like geographic atrophy or diabetic eye disease. Healthy volunteers are also needed for comparison. The goal is to understand how these conditions affect retinal function over time.

This study looks at how well the eyes function in people with early or intermediate age-related macular degeneration (AMD). It uses imaging and vision tests to help doctors better understand the condition.

This study uses specialized eye imaging to track changes in geographic atrophy, a type of vision loss from macular degeneration. Researchers will use new imaging techniques to better understand how this condition progresses and how treatments work.

This study measures a pigment in the eye and also looks at other body tissues in people who have a specific inherited eye condition called adult vitelliform dystrophy. It may help researchers better understand the disease and how it can be confused with early age-related macular degeneration.

This trial studies a light-guided eye treatment in people with generalized inherited retinal disease (a genetic cause of vision loss). It aims to see whether the approach works safely and can improve function for people whose vision is already significantly reduced.

This study tests a quick, noninvasive eye test that measures how well you see in the dark, which can be an early sign of dry AMD. Researchers want to see if the test relates to everyday tasks like reading or driving at night.
