Test of how rod and cone vision work in eye disease
Part of Eyes & vision, Genetic & congenital clinical trials.
This study measures how your eyes use two types of light-sensing cells (rods for dim light and cones for clearer detail). It may help researchers better understand retinal (retina) diseases and how well vision is functioning.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be at least 5 years old
- You (or your legal guardian) can understand the study and sign consent
- Be able to cooperate with the vision testing during the study visits
- If you have retinal disease: you must have measurable vision and clear signs of retina function loss or thinning on standard eye tests
- If you are a healthy volunteer: your vision must be 20/20 or better in at least one eye (with or without glasses/contacts)
- You must not have cloudy eye media that blocks the view of the retina during eye exams

This study tests a high-resolution imaging method that takes very detailed pictures of the retina (the light-sensing layer at the back of the eye). You might benefit by getting your eye health checked in a structured imaging study—if you’re able to comfortably complete the scan.
This study will check if certain vision tests work well in people with retinal diseases like retinitis pigmentosa or Stargardt. Results will help design future trials.
This study is looking at how people with inherited retinal disease that affects peripheral vision see and move around. It will test a new way to measure vision and navigation to see if it can help doctors understand how the disease affects daily life.
This study checks how well a device can measure how your pupils respond to colored light. It may help improve eye testing, especially when monitoring certain vision and nerve conditions.
This early-stage study uses virtual reality tasks to check how well a person can move and function using their eyesight. It may help researchers measure vision abilities in a way that could guide future care for retinal disease.
This study tests new ways to diagnose glaucoma (and sometimes related eye conditions) using eye exams and measurements. It may help improve how doctors detect glaucoma earlier and more accurately.
