Available for over a year

Professor Robert MacLaren, from Oxford's John Radcliffe Hospital, updates us on the latest gene therapy treatment as a cure for sight loss and explains who it may be able to help in the future. James White from the Guide Dogs for the Blind Association (GDBA) explains the points on which the charity disagrees, regarding comments made on last week's programme by Baroness Kramer, relating to the number of new buses being fitted with audio-visual equipment. Plus listener David Williams provides us with this week's column, in which listeners take on a subject from the point of view of visual impairment.
