What Researchers Did
Researchers investigated if bubbles forming in the tear film of the eye could indicate decompression after a simulated dive.
What They Found
The study found a significant increase (p < 0.001) in tear film bubble formation in all eleven subjects after a simulated dive to 30.48 meters (100 feet) for 15 minutes. This suggests that tear film bubbles could serve as a detectable sign of decompression.
What This Means for Canadian Patients
For Canadian divers or individuals at risk of decompression sickness, this non-invasive method could offer a way to detect early signs of decompression. Early detection might help in preventing severe decompression disorders and guide timely medical intervention, including hyperbaric oxygen therapy if needed.
Canadian Relevance
This study was conducted by Canadian authors and covers decompression sickness, which is a Health Canada-recognized indication for hyperbaric oxygen therapy.
Study Limitations
A limitation of this study is its small sample size of eleven subjects and the use of a simulated dive environment rather than real-world conditions.
