What Researchers Did
Researchers presented the case of a 43-year-old man who experienced vision loss after spine surgery and reviewed existing literature on this complication.
What They Found
They found that a 43-year-old man developed central retinal artery occlusion after spine surgery in the prone position. After receiving combined therapies, including neurotrophy, anticoagulation, vasodilation, fluid infusion, and hyperbaric oxygen treatment, his visual acuity began to recover 5 hours postoperatively and continued to improve.
Canadian Relevance
The study authors are not Canadian, and the research was not conducted in Canada. Postoperative visual loss or central retinal artery occlusion is not a Health Canada-recognised indication for hyperbaric oxygen therapy. No direct Canadian connection identified.
Study Limitations
As a case report, this study describes only one patient and cannot prove that the treatments, including HBOT, directly caused the visual recovery.
