How the macula and fovea respond to light
Light signaling in the human retina
This project looks at how the light-sensing cells in the central and peripheral retina respond to light to better understand changes tied to age-related macular degeneration.

What this research studies
This work records how individual rod and cone cells from the fovea, nearby macula, and peripheral retina react to light using precise electrical measurements. Researchers will compare response speed, signal amplification, and light adaptation between central and peripheral photoreceptors. They will examine human retinal tissue, including tissue affected by age-related macular degeneration, to identify which light-response pathways break down. The findings aim to clarify functional changes that lead to loss of sharp central vision.
Who could benefit from this research
Good fit: People with age-related macular degeneration, older adults at risk for AMD, or individuals willing to donate eye tissue or take part in retinal function testing would be relevant participants.
Not a fit: People with vision loss from non-retinal causes (for example optic nerve disease) or younger individuals without macular damage are unlikely to benefit directly.
Why it matters
Potential benefit: If successful, this could improve how clinicians detect and monitor macular degeneration and guide development of treatments that protect or restore central vision.
How similar studies have performed: Previous studies have given important insights into human rod and cone function, but direct high-resolution recordings from central human photoreceptors are rare, so this approach is relatively novel.
