High Blood Pressure and Your Eyes!

/

Having high blood pressure or hypertension (HTN) can have a serious impact on a persons overall well being along with the overall health of their eyes. It is estimated that approximately 22% of Canadians have hight blood pressure, but that only about half actually receive treatment for it. High blood pressure is considered to be a silent killer, as it often has no symptoms at all.

Elevated blood pressure is defined as having a systolic pressure of greater than 140mmHg or a diastolic pressure of more than 90mmHg. In the vast majority of people, there is no specific cause for their elevated blood pressure, but studies show that high blood pressure is more common in African Americans than in Caucasians and more common in the elderly. High blood pressure is also more likely to develop in people suffering from obesity or diabetes.
