Peter White talks to Cathy Yelf, the chief executive of the Macular Society, about the first treatment to target the underlying genetic cause of age-related macular degeneration (AMD). We feature feedback from last week’s programme in which we heard from Emily Brothers, whose guide dog was attacked by another dog. Guide dog owner Sandra Drewell, has had a similar experience. And Peter talks to Charmian Cvek about her experience of caring for her mother who was losing her sight. Charmian tells us how her mother’s sight loss affected their relationship.
