Hi Marie,
A lot of peoples eyes do have
temporary problems around diagnosis. The changing glucose levels results in osmotic pressure with more fluid entering the eye, to 'dilute' the higher glucose level. This can distort the lens and make vision blurry. This
is not retinopathy and as glucose levels get lower, some of the fluid leaves the eyes and the shape may change again. Eventually this gets back to where it should be. They always tell you not to get new glasses soon after diagnosis or if your glucose levels are higher than they should be as it will cause you to get a wrong prescription (most Opticians seem to be very aware of this but there have been a few stories of people spending a lot of money on new glasses that became useless ) This explains in a little more detail

( Remember as I said last night, you weren't at the sort of level that the article and MPB had nor probably had diabetes for the length of time they had.)
Occasionally people are diagnosed at that sort of level and have had undiagnosed diabetes for many years. Reduction of levels over a longer time could be very important in those cases.
I shouldn't worry at the moment at all, take things gradually . If you have suddenly adopted a very low carb diet then you should tell your doctor about it. He should be adjusting your drugs on the basis of your glucose levels but he may also have in mind a diet with higher carbs.
It is important though to have a retinopathy check for
everyone being newly diagnosed it establishes a benchmark.
It's one of the things the NHS should be proud of, the introduction of regular scans for all people. It was one of the first countries to do so I believe different areas do things in different ways so talk to your doctor about it. In some areas there are mobile units, in others the tests are done at the opticians. Basically you have the back of the eye photographed. Most older people need to have drops in their eyes to dilate the pupils so it's usually done as a special appointment. .
