Restoring sharp central vision using advanced retinal imaging and cell replacement
Accelerating photoreceptor replacement therapy with in-vivo cellular imaging of retinal function
This project builds high-resolution eye imaging and models to speed up treatments that replace damaged light-sensing cells for people with central (foveal) vision loss.

What this research studies
If you have lost sharp central vision, this work is creating lab models that mimic the human fovea and tools to watch single cells work in the living eye. Researchers make tiny, targeted photoreceptor injuries and then use adaptive optics and cellular calcium imaging to see whether transplanted photoreceptors connect with the host retinal circuitry. The platform lets scientists track how and when new cells restore function at the cellular level over time. The data are meant to guide safer and more effective future clinical trials of photoreceptor replacement.
Who could benefit from this research
Good fit: Ideal candidates for future trials informed by this work would be adults with vision loss caused by damage to foveal photoreceptors who may be eligible for photoreceptor replacement treatments.
Not a fit: People whose vision loss is due to optic nerve damage, extensive retinal scarring, or non-photoreceptor causes are unlikely to benefit from photoreceptor replacement approaches.
Why it matters
Potential benefit: If successful, this could accelerate development of therapies that restore central, high-acuity vision by confirming transplanted photoreceptors integrate and function correctly.
How similar studies have performed: Early animal studies of photoreceptor transplantation and advanced imaging have shown promise, but restoring high-acuity human foveal vision remains largely unproven in clinical settings.
