@noblehead Thank you for your comments. Some people may be guilty of handling their condition in a foolish way - but that is not me. The reason for my original post was the fact that the screening for retinopathy was done one week before the optician's eyesight test.
When I had recovered from the screening blitz on my eyes I was sitting five feet away from and in full view of the enlarged (about fifteen inch square) images of the inside of my eyes. The follow-up letter reported that there were no retinopathy issues found. Armed with that boost in confidence I proceeded to my annual eyesight test. I know I have no severe vision problems as my prescription has only varied very slightly in the last twelve years.
I know that I am not trained to interpret the retinopathy screening images but I saw nothing that in any way resembled the images of 'hard exudates' that I have seen on Dr Google. What I need to know is that if the optician has found hard exudates then how long does the condition typically take to deteriorate to the point where my vision will be affected in an adverse way.
I will, for peace of mind, have a private retinopathy scan. I shall also have another eyesight test with a different optician.
@kesun Kate, thank you for your comments too.
