Ashton Kutcher is opening up about the vasculitis diagnosis that left him unable to see and hear.
CNN reports that the autoimmune disorder occurs when the body's immune system attacks veins, arteries and small capillaries. The resulting inflammation narrows those blood vessels and restricts blood flow or even cuts blood flow off entirely, sometimes causing organ damage or creating aneurysms. If an aneurysm bursts, it can cause internal bleeding, which can lead to death.
During an episode of Running Wild With Bear Grylls: The Challenge, the actor opened up about his diagnosis.
"Like two years ago, I had this weird, super-rare form of vasculitis," he said in a clip shared by Access Hollywood. "Knocked out my vision, knocked out my hearing, knocked out like all my equilibrium. It took me like a year to like build it all backup."

"You don't really appreciate it until it's gone, until you go, 'I don't know if I'm ever going to be able to see again. I don't know if I'm going to be able to hear again, I don't know if I'm going to be able to walk again," the Vengeance star says in the clip. "I'm lucky to be alive."
Running Wild With Bear Grylls: The Challenge is available to stream on Disney+ in South Africa. The above episode and new season has not yet been released.
