She told The Daily Beast website that she's suffering from Glaucoma and Macular Degeneration. It's a condition that causes distortion, fuzziness, and can ultimately total vision loss in the center of the eye.

Dr. Robert Maloney, Director of the Maloney Institute in Los Angeles, told INSIDE EDITION, "One of the dangers of Glaucoma is you don't know you've got it until it's too late. It affects your vision in the periphery first and gradually closes in, so you don't tend to notice it. All of a sudden, you finally figure out, 'wow, I can't see,' and it's way too late."

She says that doctors have not given her a timeline on when she will become blind, but her eyesight is deteriorating fast.
