Both newspapers were relating the story being told by Professor John Marshall of King’ College in London, about the new laser he and Ellex of Australia are working on that can be used with patients with macular degeneration to ”clear” Bruch’s membrane and regenerate broken down retinal tissue.
As related by Professor Marshall, he has developed a way of "cleaning" eyes which, due to the aging process, have accumulated tiny particles of debris which start to cloud their sight. His pioneering technique uses a painless "short pulse" laser to solve the otherwise intractable problem of how to help the eye's waste disposal system do its job after it has been weakened by age.
Marshall, a senior ophthalmologist at King's College London, said he hopes this "retinal regeneration therapy" can prevent and reverse the onset of AMD.
The technique works by rejuvenating a thin membrane behind the retina, called Bruch's membrane. Over time this membrane becomes so "clogged" with the by-product of cell renewal that vital nutrients can no longer cross from the bloodstream into the retina and excess material becomes trapped, unable to pass in the other direction. This leads to the death of retinal cells and, in time, to AMD and eventual blindness.
This is not new technology. I wrote the original article about Ellex’ 2RT Retinal Regeneration Technology in my online Journal back in November 2007,
