I m writing in regard to a friend . I took him to the eye doctor today and they said he has fluid or blood behind his right eye. He woke up this morning and could not read out of that eye and everything is real blurry. He does have diabetes. he went and had blood work done also. He did go see a eye doctor that does surgery. he has a lens in that eye for reading and his other eye has one for distance. I am worried he could have had a mini stroke, didn't tell him that because I did not want to scare him He is also 70 years old and has no heart problems, does have high blood but controls it
