I was amazingly privileged today to witness an operation at the Royal Veterinary College. The horse concerned had recurrent uveitis and this clever procedure involves inserting a slow releasing pill into the surface of the eye; the pill supresses the autoimmune system in a very specific location. It was fascinating to watch. As I happened to have my camera with me, the professor in charge of the operation asked me to take a close up. I was at the college with Jim Green who was giving a talk on Animal Rescue to the fifth year veterinary students as part of their elective subjects.
