Valporic acid is now being tested on human patients suffering from autosomal dominant forms of retinitis pigmentosa (adRP). This drug has already been approved for people with seizures, but the National Eye Evaluation and Research (NEER) network is now looking at how the drug can help those with this inherited form of RP.
Participants in the trial are taking the medication orally through the duration of the trial. Some will be treated with a placebo. Visual field tests will help researchers determine the effectiveness of this treatment.

Certain nutrients such as vitamin A, lutein, omega-3 fatty acids, other antioxidants, and COQ10 may help slow down retinitis pigmentosa and help to preserve vision.
