Hypertension update.

Hypertension affects approximately fifty million Americans. About 80% of hypertensive patients are aware that their blood pressure is elevated. While more than 50% are on medication, only about 20% of all hypertensive adults are controlled at normotensive levels. Ophthalmologists should be aware of the seriousness of hypertension because it affects many of their patients and is a risk factor for myocardial infarction, stroke, congestive heart failure, end-stage renal disease and peripheral vascular disease. As medically trained eye specialists, ophthalmologists should be knowledgeable about and take an interest in their patients' medical problems, thus playing an integral role on the health care team. As a primary health care provider, ophthalmologists should perform in-office blood pressure monitoring.
