What Researchers Did
Researchers administered hyperbaric oxygen treatment to a 26-year-old man with retinitis pigmentosa for 97 minutes daily, five days a week over four weeks.
What They Found
After the four-week treatment period, the patient experienced improved lateral vision and achieved higher scores on an intelligence test, with a gain greater than usually found as a practice effect. A reversible reduction in gas diffusion for CO (TLCO) was observed, but no adverse central nervous system effects were found.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A significant limitation of this study is its single-patient case report design, which limits generalizability of the findings.
