As those with vision loss continuously hope for new sight-saving treatments, last week reports came of a new 'red light therapy' which claimed to help improve worsening eyesight. Given the importance of this news to sight-loss patients, the Macular Society has investigated the science behind the news reports. At this time, the charity does not find the therapy to be effect for macular disease patients.
The study, which was conducted by University College London, required 24 people - who notably, were unaffected by eye disease - to stare into a long wavelength light for three minutes everyday.
Following the study, some participants (aged 40+), showed an improvement in the ability to see in low light, as well as 20% improvement in colour detection.
The Macular Society has reported that although this research is 'interesting', another study did not find the treatment to be effective in individuals who do have any type of macular disease. The charity have clarified though that this may be due to the length of the study, and so further studies are needed. At the point in time, the Macular Society has expressed caution towards this research, as these studies have not yet been proven to be effective for those with dry macular disease. The organisation has also discouraged this form of treatment for wet MD.
As research continues for longer periods and with a more representative sample, it is possible that advice could change, however, for now, it is beneficial to have this clarity from the Macular Society on the true success of red light therapy for MD patients.
