Ultrasound Stimulation Retinal Retinitis Pigmentosa Age Related Macular Degeneration

ClinConnect Summary

This clinical trial is exploring a new way to help people with vision loss due to age-related macular degeneration (AMD) and retinitis pigmentosa (RP). Researchers are testing a non-invasive device that uses high-frequency ultrasound to stimulate the retinal nerve cells in the eye, which could potentially restore some vision. Unlike other methods that require surgery and can be risky, this ultrasound approach is designed to be safer and easier for patients. The study will follow strict safety guidelines to protect everyone involved.

To participate, individuals need to be 18 years or older and have a diagnosis of AMD or RP without any other serious eye conditions. Participants will undergo some eye scans before and after using the ultrasound device and will experience several cycles of stimulation. They will also fill out a questionnaire to share their experiences and any changes in their vision during the process. It's important to note that this study is not yet recruiting participants, but it aims to find safe ways to help those with specific vision problems regain some sight.
