High altitude could prevent glaucoma

High altitude could prevent glaucoma

Posted on 15th April 2012

A very interesting study using mice has found that intermittent exposure to low levels of oxygen (such as might be found at high altitude) can strengthen retinal nerve cells and prevent glaucoma.

retinaThe stress of the intermittent low-oxygen levels promoted a protective response called ‘tolerance’ which makes the nerve cells less prone to damage. Normal mice with glaucoma lost an average of 30% of nerve cells after 10 weeks with the condition, but the mice that were exposed to the oxygen stress lost only 3% of nerve cells.

This research potentially has application in other neurodegenerative conditions such as  Parkinson’s and Alzheimer’s.

Previous research we highlighted on this blog shows an increasing interest the theory of classing glaucoma as a neurodegenerative condition rather than related to decreased blood supply or mechanical pressure as traditionally thought.
