Okuvision has announced that its electrical stimulation therapy has proven effective in early-stage retinitis pigmentosa patients during a sham-controlled pilot study.
The study involved 24 patients who were separated into three groups and received electrical stimulation therapy at varying strengths for 30 minutes once a week, over a period of six weeks.
The first group was treated without electrical current, the second with 67% of the individual threshold, and the third with 150% of the patient’s threshold.
The final result showed a 20% significant improvement in the field of vision by patients who received the 150% stimulation.

The findings emphasised that electrical stimulation of the retina liberates growth factors that may delay its degeneration.
