I live in pembrokeshire and since I was diagnosed as type 2 almost 7 years ago, I have had an annual retinopathy eye check arranged by N.H.S. Wales. I then usually get a letter about 2 or 3 weeks after the check informing me of the results. However, having had a check in April, this year, I hadn't received a letter. I contacted them and they replied that there had been delays in processing them and it may take up to 6 weeks! It actually took over 6 weeks. Fortunately there were no changes from the previous check, but I wasn't impressed.
I may not bother next year if the service is that poor!
To be fair to them, if they have a large number to process, they would have left the non urgent ones and concentrated on the urgent cases which were flagged up by the person doing the screening.
