Mary Tyler Moore, star of her eponymous show that began in 1970 and chronicled women’s changing role in society, is nearly blind, friends say.

Closer Magazine has an exclusive about the 77-year-old actress’s condition:

“Her eyesight is what the big problem is right now,” former Mary Tyler Moore Show co-star Betty White reveals to Closer.
Mary, who was diagnosed with Type 1 diabetes when she was only 33, “is almost beyond the point [of being able to see],” Betty says.
The illness forces Mary to stick close to home these days, though she stays connected to her longtime friends via frequent calls.
“I don’t see her often, but I talk to her a bunch,” Dick Van Dyke, who played her husband on “The Dick Van Dyke Show,” reveals to Closer. “She hasn’t been too well. She’s really having a battle with it, I’m sorry to say.”

In 2011, Moore’s spokesman, Alla Plotkin, told the Daily Mail that Moore had undergone surgery to remove a meningioma, a benign tumor of the lining tissue of her brain. Since 2012, it’s been reported that her mobility has declined and she’s suffered heart and kidney problems.
