Is Hyperbaric Oxygen Therapy Always Useful When Treating Vision Problems?

Hyperbaric oxygen therapy (exsposure too oxygen at high pressure) is sometimes used to treat certain vision problems. But will this treatment work for everyone? CBR member Frank Giblin, Director of the Eye Research Institute, and his colleagues think not. In a paper published in the April 2009 issue of the Archives of Ophthalmology (Loss of Protein Kinase C gamma in Knockout Mice and Increased Retinal Sensitivity to Hyperbaric Oxygen, Volume 127, Pages 500-506), Giblin performs experiments on mice and concludes that in certain individuals with a particular genetic defect, hyperbaric oxygen therapy may do more harm that good.
"Protein kinase C gamma-knockout mice had increased retinal sensitivity to [hyperbaric oxygen]. Results demonstrate that [Protein kinase C] gamma protects retinas from [hyperbaric oxygen] damage...Care should be taken in treating patients with [hyperbaric oxygen], particularly if they have a genetic disease, such as spinocerebellar ataxia type 14, a condition in which the [Protein kinase C] gamma is mutated and nonfunctional."
