| Same thing with me.Those times i didnt need any glasses but not have a perfect vision.When i first diagnosed and after having the first insulin shots my eyes become like the eagles eyes but then turned to normal in few weeks..
In my opinion there may be relation with the iv drag..cause twice i was about get into coma.I never lost a my consciousness but started to vomit up uncontrollablely and eventually i was admitted in the hospital both times and after the iv drags my vision become better than general for a short period of time. |
