The effect of treatment of blood pressure between 130/80 mmHg and 160/100 mmHg is less clear, with some reviews finding benefit [6] [16] [17] and others finding unclear benefit.

A major aim of treatment is to prevent, limit, or reverse target organ damage by lowering the person's high blood pressure to reduce the risk of cardiovascular disease and death. Treatment with antihypertensive medications may be required to control the high blood pressure.
Third Eye Diagnostics, Inc. is developing the Cerepress™, a non-invasive, hand-held intracranial pressure monitor that gathers information from the patient's un-dilated eye. The Cerepress™ measures blood pressure in the eye's central retinal vein (CRV) and blood velocity in the ophthalmic artery, which taken together highly correlate to ...
