I have RP. The only thing I have heard of as far as technological help is the Retinal Implant. This implant, basically, is a camera implanted at the retina that sends visual stimuli to the visual cortex. Its a cortical implant. They are in clinical trials now, with two humans having had the implants. I have heard no more. Register with the Foundation Fighting Blinness. (blindness.org, or FFB.org)
