[IPd] Research Suggest Pure Oxygen Helps to Heal Damaged Retinas

>From UC Santa Barbara Today, Winter 2001 issue
...a new treatment, still in the early stages of clinical practice, 
can help save the cells of your retina if you receive it while you 
wait for your surgery, and before too much damage has occured. The 
treatment is simple but very effective: Breathing pure oxygen will 
help to ameliorate the damage to the eye. Santa Barbara 
opthalmologist Robert Avery is also a research associate of the 
Neuroscience Research Institute at UC Santa Barbara. The treatment 
was first developed there under the director Steven K. Fisher, who 
worked with researchers in Australia.

Two studies on oxygen's effect on retinal detachment, which were 
co-authored by Fisher and Avery were published in the American 
Journal of Opthalmology. 

..... During detachement (of the retina), the thin lining of 
light-sensitive nerve fibers and cells covering the inside wall of 
the eye is damaged. The retina is separated from its only source of 
nutrients and oxygen, the choroid, a bed of capillaries that serves 
to transport them. With oxygen therapy, the retina is resupplied with 
more of those life-sustaining molecules.

......Even though these findings published by the UCSB institute were 
the result of animal studies and not clinical trials on humans, such 
as the ones beginning soon in Santa Barbara and Australia, Fisher 
said that the results were so compelling that he urges opthalmologist 
everywhere to consider supplying oxygen to patients with retinal 
detachments while they await surgery.
