Went back to East Surrey Hospital for more examination of my left eye. The news is good, though no different from the last visit, but with added explanation. The bleeding that caused the ‘floater’ was created by the jelly bag of the eye shrinking with age (universal) and detaching from the back of the eye. The floater will stay but probably fade with time. There is risk of retinal detachment (serious) within 3 months of the original injury, but as I cannot be sure when that was I may be out of the danger time already. With that diagnosis came the assessment that my eyes are in truly remarkable shape for diabetic of 45 years standing.
