Bob Bard thinks he may have figured how to use oxygen therapy on pinkeye  in cattle. Bard, who is a North Texas optometrist and beef producer, says when his cattle have developed pinkeye  in recent years he's been spraying ozonated, distilled water into the infected eye several times over a day or two. He says usually the eye clears right up.
Oxygen therapy is not unusual for a variety of maladies, including eye problems , but it’s not well known or well accepted across the medical community. It is sometimes used in hyperbaric conditions, meaning the patient  is put in a pressurized chamber with higher-than-normal oxygen content. Or the oxygen may be delivered straight into the airways for breathing, thereby increasing oxygen content in the blood.
