Testing a New Way to Measure Vision Loss in Eye Disease

This trial is testing a new device called a chromatic multifocal pupillometer—a specialized camera that measures how your pupils (the dark circles in your eyes) react to different colors and intensities of light. Researchers want to see if this device can detect vision loss better than traditional eye tests in people with glaucoma or inherited retinal diseases.

Current eye tests don't always catch early vision loss or show exactly which parts of your vision are affected. This new device measures your pupil's automatic responses to light across your entire visual field, which may offer doctors a faster, more objective way to monitor these eye diseases.
