What Researchers Did
Researchers investigated the effect of hyperbaric oxygen (HBO) therapy on central corneal thickness in 32 subjects, divided into diabetic and nondiabetic groups.
What They Found
HBO treatment did not significantly change central corneal thickness in diabetic subjects (547.6 ± 34.5 vs. 548.6 ± 34.6 μm; p = 0.606). However, in nondiabetic subjects, central corneal thickness was significantly reduced after HBO treatment (576.5 ± 34.8 vs. 569.0 ± 34.8 μm; p < 0.001), though this change was minor.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada nor involved Canadian researchers or participants.
Study Limitations
A limitation of this study is that it only examined the effect of a single hyperbaric oxygen exposure, and the observed changes were minor.
