Repetitive Transorbital Alternating Current Stimulation for Optic Neuropathies
Trial Parameters
Brief Summary
The purpose of this study is to test the efficacy and feasibility of an intervention protocol for home-based repetitive transorbital alternating current stimulation (rtACS) for the treatment of visual impairment in people with optic neuropathy. The primary aims are to evaluate the effectiveness of home-based rtACS to ameliorate the progressive effects of vision loss functionally in the eye and the visual pathway, and in regard to people's independence (i.e., functional ability).
