My 69 year old mother who has been blind for over a year in her left eye, her iris is now completely black?

My 69 year old mother who has been blind for over a year in her left eye due to an injury she suffered from sneezing to hard over two years ago. She went to an eye doctor last year when she lost sight in her eye. He said there was nothing they could do. So no problems until last night. She had a headache and took some medicine to stop it. When I brought her dinner I noticed her iris in the left eye was completely black. The white of her eye is still there. She said this morning she feels fine. Her iris is still black. Do I seek help for her?
