Basically. The only cure for the blindness, at least that I know of, is to awaken the Eternal Mangekyō Sharingan which involves stealing a sibling's or close relative's eyes.
I had sustained injuries from my fight with my brother, a bad wound and burns on my right arm specifically. My eyes were bleeding, that was from the use of the Mangekyō Sharingan, and I had apparently been coughing up a little bit of blood and had a mild heart attack due to the stress on my body. In my dreams I was suffering from a fatal illness as well, but I never knew the name of it. I'm hopeful that they will find something, it would be nice to have a little peace of mind and try to figure out the next course of action in regards to my health.
