Mary Tyler Moore Nearly Blind, Say Friends Betty White says diabetes has taken a toll By Newser Editors, Newser Staff Posted May 21, 2014 7:10 PM CDT 18 comments Comments Mary Tyler Moore in a 2012 file photo. (AP Photo/Mark J. Terrill, File) (Newser) – More than four decades of dealing with diabetes has left Mary Tyler Moore nearly blind, reports Closer Weekly. Its story isn't based on anonymous sources but familiar ones: "Her eyesight is what the big problem is right now,” says longtime friend Betty White. "She is almost beyond the point (of being able to see)." And Dick Van Dyke adds that "she's really having a battle with it, I'm sorry to say." The story says the 77-year-old, who was diagnosed with Type 1 diabetes at age 33, sticks close to home under the watchful eye of husband Robert Levine, a cardiologist.
