Late hyperbaric oxygen treatment of cilioretinal artery occlusion with nonischemic central retinal vein occlusion secondary to high altitude.

What Researchers Did

Researchers reported a case of a 48-year-old woman who developed cilioretinal artery occlusion and central retinal vein occlusion after high-altitude exposure, successfully treated with late hyperbaric oxygen therapy.

What They Found

The patient's initial best corrected visual acuity (BCVA) was 10/20 in the right eye, which improved to 20/20 after 11 days of daily hyperbaric oxygen treatment. Additionally, visual field scotomas resolved immediately following the treatment.

Canadian Relevance

This study has no direct Canadian connection.

Study Limitations

A major limitation of this study is that it reports only a single case, limiting the generalizability of its findings.
