I m 58, 162cm, 70kg, fit and active. Have hypertension, diagnosed 10 years ago but blood pressure usually very well controlled. About two weeks ago, following a brief period of unexplained elevated blood pressure, and during a workout session, I noticed a mark appearing in my peripheral vision in my right eye. I thought I had perspiration in my eye but it hasn t gone away. My blood pressure is back to normal and there has been no answer to the cause of the spike. However, this strange mark, like a hair in your eye remains. Hasn t gotten any worse in fact, think it may have diminished slightly. Are you able to provide and clues as to what this may be?
