10 days ago, husband went to optician as he had black spots, floaters. She said it was OK. Got worse, went back 5 days later, told he had a detached retina, go to a and e as it was urgent. Doctor there checked it, referred him to large eye hospital 55 miles away. Appointment there 3 days later. Got prepped for surgery then sent home as they didn't have time to do it. Supposed to have this procedure within 4 days otherwise go blind. He's making noises about reporting the optician for not spotting it at the 1st visit. Any advice?
