Lion,
Good question!! I am also having major probs wtih my both eyes.
I have to have artificial lens' put in them, I am on a waiting list right now, but the eye doc said he cant guarantee i wont lose sight in both eyes When I asked if it was the plaquinal or lupus, he just shrugged his shoulders and said..mmmm probably the diabetes...but I havent been a diabetic for long, PLUS I am very very disciplined with my diet, so I dont think it is the diabetes
I will keep you in my prayers Lion, and hope you get better news than I did
Diane
