(USA TODAY) -- Mary Tyler Moore has been fighting type 1 diabetes since she was 33, and now, at 77, the disease has taken a debilitating toll, according to her old friends and co-stars. Betty White tellsCloser Weekly:
Her eyesight is the big problem is right now … (Mary) is almost beyond the point (of being able to see).
Dick Van Dyke talks to her on the phone:
She hasn't been too well. She's really having a battle with it, I'm sorry to say.
Valerie Harper, struggling with her own health woes, of course, says diabetes "does ravage (Mary's) body, but she stays healthy."
