What Researchers Did
Researchers investigated whether hyperbaric oxygen (HBO) therapy could improve temporal visual field (TVF) defects in 12 patients who developed this complication after macular hole surgery.
What They Found
Among the 12 patients with TVF defects, 7 received HBO therapy and 5 served as controls. All 5 control patients continued to have TVF defects, whereas the visual field recovered significantly in all HBO-treated patients. The visual field recovered to 81.7% of the preoperative level after 3 days of HBO and to 91.6% months after therapy.
Canadian Relevance
This study has no direct Canadian connection as it was conducted by researchers in Japan.
Study Limitations
A significant limitation of this study is its very small sample size, which limits the generalizability of the findings.
