What Researchers Did
Researchers measured the curvature of volunteers' eyes inside a hyperbaric chamber to investigate reports of blurry vision experienced by scuba divers at depths below 100 feet.
What They Found
They found that as the pressure inside the chamber increased, the corneal reading showed a higher dioptric value, indicating a change in eye curvature. This change in refractive condition was also observed when measuring test steel balls under the same increased pressure.
What This Means for Canadian Patients
This study explores how increased pressure affects eye curvature, which could be relevant for Canadian scuba divers experiencing temporary vision changes at depth. It does not directly relate to the therapeutic use of hyperbaric oxygen treatment for medical conditions.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
The study did not definitively determine whether the observed changes were due to increased atmospheric index or displacement of the instrument's optics.
