Modulating Ocular/Retinal Blood Flow and Visual Function in Retinitis Pigmentosa
Retinitis pigmentosa (RP) is a slowly progressive retinal degeneration for which there is no
proven treatment. Patients are interested in trying alternative therapies to try to reduce
their vision loss, but only limited research evidence exists to support their use and
potential benefit. The goal of this research project is to gain a better understanding of
possible changes in ocular and retinal blood flow and measures of vision in RP patients
receiving two promising therapies, electroacupuncture and transcorneal electrical
stimulation.
