Devotees of Coronation Street will no doubt know that the character, Johnny Connor, is experiencing hallucinations caused by the little-known eye condition, Charles Bonnet Syndrome. In this podcast, Tom Walker talks to Judith Potts   from Esme's Umbrella and Nina Chesworth about their work with the Coronation Street script-writers to understand the eye condition. Judith's organisation supports people like Nina who have CBS. Judith tells Tom about the level of detail the script-writers needed to go into and Nina talks about her conversations with the actor Richard Hawley, who plays Johnny Connor.
