High BP can threaten vision

A new study in Investigative Ophthalmology & Visual Science (www.arvo.org) indicates that chronic high blood pressure increases susceptibility to glaucoma.

Glaucoma is the second leading cause of blindness in the world--it results in too much pressure inside the eye.

The new research was done at the Univ of Melbourne in Australia and is significant because it was previously thought high blood pressure counteracted internal eye pressure.

They even raised BP in young people for an hour to see if it helped the eye pressure.

However, this became a risk factor in older people. Over time, researchers think, high pressure may damage vessels in the eye.

They are testing this in rats--but you know what? Try to control high blood pressure if you can, just in case, OK?

I am all about eyes and vision, since losing sight in one eye--you do not want this.
