What Researchers Did
A prospective study investigated the rate of myopic change in 44 eyes of diabetic patients undergoing hyperbaric oxygen therapy.
What They Found
Researchers found a statistically significant positive correlation between hyperbaric oxygen treatments and a myopic shift in refraction. The spherical equivalent (SE) changed by 0.61 diopters (D) and the sphere component (SPHER) by 0.58 D, accumulating from the first examination.
What This Means for Canadian Patients
Canadian patients undergoing hyperbaric oxygen therapy, particularly those with diabetes, should be aware of the potential for temporary myopic changes in their vision. Regular eye examinations during and after treatment can help monitor these refractive shifts.
Canadian Relevance
This study has no direct Canadian connection as it was conducted in Israel.
Study Limitations
The study's findings are specific to diabetic patients and the temporary nature of the myopic shift, which may limit generalizability.
