High Blood Pressure Raises Glaucoma Risk: Study

By    |   Tuesday, 06 Jan 2015 05:23 PM

A new study suggests that high blood pressure raises the risk of developing glaucoma, the leading cause of blindness.
 
Glaucoma occurs when too much pressure builds inside the eye. The excess pressure prevents blood from entering the eye, resulting in vision loss.
 
Previous research had indicated that high blood pressure could actually prevent glaucoma by counteract the high eye pressure that leads to the disease. These studies found that raising blood pressure for a short period (one hour) offered some protection. However, other data found that although hypertension was protective in young people, it increased risk for those who were older.  
 
“Studies have shown that high blood pressure is a risk factor for glaucoma. But the reasons for this were never clear,” said author Bang Bui, Ph.D, lead author of the Australian study, which appears in Investigative Ophthalmology & Visual Science.
 
The new study shows that instead of being considered beneficial, high blood pressure should be viewed as a risk factor for glaucoma, Bui said.
