What Researchers Did
Researchers reported a case of a 43-year-old male with type 2 diabetes who developed proliferative diabetic retinopathy during hyperbaric oxygen treatment for plantar ulcers.
What They Found
A 43-year-old male with a history of treated proliferative diabetic retinopathy (PDR) developed new pre-retinal hemorrhage in his left eye after five hyperbaric oxygen treatments (HBOT). After 12 additional HBOT sessions, worsening proliferative changes were observed in both eyes, despite his visual acuity remaining 6/9 bilaterally.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
As a single case report, the findings may not be generalizable to all patients undergoing hyperbaric oxygen treatment.
