Electrical currents could help restore sight

Techniques using electrical pulses that could help people with eye diseases are being tested by Fight for Sight funded researchers at the University of York.

Professor Antony Morland, University of York, has undertaken research to see if small electrical currents can stimulate the brain to protect against physical changes related to conditions including AMD.

Professor Morland said: ‘We already know that AMD causes the key area of the brain that processes vision to stop receiving signals from the eye. This can cause specific parts of the brain to shrink meaning they are likely to be less receptive to any potential sight restoration treatments; possibly limiting their success.
