What Researchers Did
Researchers described three cases of orbital emphysema, a rare complication of retina surgery, occurring in patients who traveled to higher altitudes after pars-plana vitrectomy.
What They Found
Gas was found in the orbit and periocular tissues of all three patients, causing orbital compartment syndrome in two. One patient with orbital compartment syndrome responded well to hyperbaric oxygen therapy, while the other patient who refused treatment continued to have gas despite surgical intervention. The third patient without compartment syndrome recovered fully without intervention.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada nor involved Canadian researchers or patients.
Study Limitations
A significant limitation of this study is its small sample size, being a case series of only three patients, which limits generalizability.
