What is the cause of extremely bad bloodshot eye?
Ive had a blood vessel burst in my eye which left the part thats usually white a scary looking red, my wife said how she went to the Drs some time back & it just goes right on its own, mine seems to be slowly. I cant say for sure if this is what yr Dads got if he is worried or it gets worse in about 5 days Id say go to the Doc again… but I think he’ll be O.
