Eyesight

[Russell A.]

Okay, so we all ate candy this weekend. My BG shot up for three nights now. My vision is terrible right now. I am wondering from your experience how long your vision is impaired from having a period of high BG?

Mine seems to last 2-3 days once I get back under control.

took me a couple weeks to get my eyes working normally. If you are farsighted b/c your sugars came down, it should be a matter of a few days!

I'm still waiting for my vision to get back to normal, and it's been nearly three weeks since I had insanely high BG readings.

NOTE: I have seen my ophthalmologist to confirm nothing is seriously wrong with my eyes. He prescribed Transitions lenses that let me tilt my head up/down to compensate for the changes.

My vision usually corrects itself (my eyes also start feeling better) within hours, shortly after my blood sugar has stabalized and gone back down for a couple of hours...
Except for those times where I have an extremely high bg level (20 or higher) and it stays really high for several hours at a time and/or overnight. In those instances it might take a day or 2, possibly longer

[jer.lawrence]

I'd say that it took mine (after diagnosis) a good 2 and a half to 3 weeks to stabalize, but that was after a pretty extended period of high numbers.

Hopefully yours will be much shorter lived since you were only up for a little while.

Russell... step away from your kid's candy!!!

I asked the opthalmologist why this happens. Has been a while since then but his explanation was clear. He said the saline balance in your bloodstream changes quickly with any blood glucose change. Wider and longer swings act to change the saline even more and for a longer time.
It is these changes in the saline levels that cause the eyes to go out of focus.

I was diagnosed a couple of weeks ago and my sugar levels dropped fast when I started to do the right things and now every thing is so blurry, it scares me. Mine was about 400 when I went to the Dr. and now I have got it to range from 90- 120 But this blurry vision thing really kreeps me out. Hope it clears up quick it has not been a week yet.

Russell.........I did NOT eat any of the leftover candy from Halloween! I'm tempted, believe me, but so far, so good! LOL

As far as vision goes, I find if my BS is out of whack and has been running high for a few days that it normally takes several days to get back to normal.

When first diagnosed - a couple of weeks to settle down. Now with a day or so of whacky numbers, it might take 1/2 to a full day to return to normal, given good control.

[Gangrel]

I actually can't recall any instance of vision changes with high BG. And I occasionally go up to the 20's. Maybe because I usually correct it pretty quickly?


Now, hypos definally give me spotty vision.....

[michelby]

I had Lasik done about 3 months ago before I was diagnosed with type 1, and I was diagnosed about 3 weeks ago...and now my vision is a little blurry.

Do you guys think I am going to need an adjustment done to my eyes, or will this go away?

[Subby]

Michelle: definitely warrants going back to your doctor. Unfortunately your eyesight may have been out when the surgery was done. One for the specialist.

I just wanted to add that your brain or eyes doesn't have a glucose storage mechanism or a buffer. When eating high GI foods they will be absorbed in part through the mouth without being digested in the stomach. As soon as the glucose hits your blood stream your eyes and brain will be one of the first places hit. That blurred vision or light seeming brighter than it actually is could be caused by your retina expanding as the blood vessels get clogged with glucose blocking the light. Which is why one long term complication of diabetes is retinopathy (http://www.diabetes.org.uk/Guide-to-diabetes/Complications/Long_term_complications/Retinopathy/).

I am not saying that you have retinopathy or trying to make a diagnosis, only informing you. See a Dr if it continues.
