A comedian fears he would have died if he hadn't visited the opticians for a routine check on floaters in his eye - despite initially thinking the symptoms "would just go away".
Chris Norton Walker discovered he had been living with life-threatening conditions, which risked blindness for years, when he was dashed to hospital.
The 40-year-old man had experienced dots and lines in his vision and, though he thought they "might fix themselves", he popped to his nearest opticians to be sure.
