It's a fairly common occurence Robin and there is no treatment for the ruputred vessels themselves, except time. It can be caused by high blood pressure, coughing very hard or a really violent sneeze, bearing down (if you know what I meand) anything that might cause an increase in the intraoccular pressure. I would get it checked out but it's not an emergency situation as far as your eye is concerned. The important thing is to make sure there isn't a more serious underlying cause, like high BP. Try not to worry but do get it checked out You didn't do something to injure your eye, did you?

Just read you're on your way to urgent care. Glad you're getting it checked out for your own peace of mind

P.S...I speak from experience; has happened to me when I've had a bad chest cold and coughed very hard
