Researchers at The Vision Centre and The University of Sydney have discovered a possible new therapy for the treatment of vision loss associated with complications from Parkinson's disease. Recent studies have demonstrated that Near-Infrared Light (NIR) treatment can protect the retina from toxins which attack its nerve cells. Using a mouse 'mode' of Parkinson's disease, in which a toxin is used to create a Parkinson-like condition, researchers used the NIR to block the effects of the toxin. The NIR offers better protection than the current established treatments for Parkinson's disease. The results of these study findings now need to be translated to human patients diagnosed with Parkinson's. Since the radiation used in the therapy is effective at low intensities and has no known toxicity, human trials should be able to be conducted as soon as possible.
