My father has
Diabetes & High BP problem. A couple of days back my father developed a blood clot in his left eye. We consulted an eye specialist. He said that my father's blood pressure shot up for a while and that led to narrowing & breaking of vein in the eye. He further assured us that the clot will disappear in a week's time.
I would like to know if this can have any adverse effect on his eye in future. Does he need to take any precautionary measure to avoid such problem in future? If yes, then what should be the precaution. How can he get rid of this problem permanently?
He is 62 years of age and a retired government employee.
