My brother is 72 years old, has had a triple bi-pass about ten years ago. Recently, he has been dianosed with COPD, A.F. , has circulation problems, on O2 at night. I just talked to him and he states, he having halos in his vision with a increase in floaters. Also, has a pain on top of his head. Do you see this as a emergency situation? I told him if his symptoms get worse or change, to go to the E.R.
