Summary

This study looks at people with retinitis pigmentosa and similar eye diseases who already use a device called OkuStim® that sends mild electrical pulses to the eye. Many patients report temporary improvements in vision right after treatment, but these haven't been measured in a standard way. Researchers will test 30 adults using eye charts and other tools to see if these short-term benefits are real and can be tracked.
