Sorry but I do not miss the point at all on this. Please reflect about it: It does not make any risk benefit sense to in order to prevent damage to the retina in the future to do damage to the lens/cornea now by guidelines and hence GPs following them advising BG levels to go down so steeply even in otherwise healthy folks like myself two weeks ago - and those posts from other people in similar situation all over the world that I have been digging up to look for reassurance while completely terrified by what is happening to my vision. BOTH the retina and the cornea are crucial to an effective vision. What good is for me or someone else newly diagnosed to have a perfect retina as confirmed by an opthalmologist yesterday in the eye casualty emergency unit if when I write in this computer this one box where I am writing as to occupy the entire 27 inch screen so that I can see the text and when I walked in a supermarket this AM or in a bookstore yesterday I couldnt read any food label or book even, in despair after trying large hardcover books with no success, large print books for children? I can thus painfully witness that the lens of the eye is very important for vision. Maintenance of good vision, either via healthy nonstressed retina (avoiding the stress of high uncontrolled BG) or lens of the eye non stressed (avoiding the stress of steep declines in BG) should be one of the crucial objectives in diabetes complications prevention and treatment. In fact in the 2 weeks since I have been diagnosed I read everywhere that the rewards of keeping BG lower and under control are precisely to keep our vision, feet, kidneys and heart functioning properly. And I believe that surely advising something (bring BG levels ASAP the clinical pharmacist even suggested to double the metformin dose!) that affects the lens of the eye / cornea so much shouldnt be done so lightly as it is being done to newly diagnosed folks like myself without any warning or caution or even recommendation on what to or expect if it happens. I am glad I found this forum otherwise I wouldnt even have hope of this improving. I guess the good news is that unlike the retina the lens of the eye apparently can adjust and come back from poor functioning in 6 weeks. But mine has not come back yet this week and has the opthalmologist said yesterday they believe it will come back in a couple of weeks, have seen that in other patients, but dont have the gospel if in any specific case it will indeed come back and well if it doesnt comeback they say I will have to wear glasses all the time to function. This when until less than 2 weeks ago I only needed glasses to read very fine print in paperbacks. I believe this crazy and is indeed to start a fire (lens of the eye affected now severily even if I surely hope so temporarily due to BG steeply going down) to prevent a fire (retinopathy in the future).
