Summary

What Researchers Did

Researchers conducted a prospective study to evaluate the effect of hyperbaric oxygen (HBO) on 14 eyes with cystoid macular oedema (CME) secondary to retinal vein occlusion.

What They Found

Visual acuity improved by 2-6 lines, averaging 3.6 lines, in the 14 HBO-treated eyes, while 12 control cases showed little improvement. Although the therapeutic effect was stable and visual function enhanced, fluorescein angiography did not show reduced leakage from perifoveal capillaries.

Canadian Relevance

This study has no direct Canadian connection.

Study Limitations

A limitation of this study is its small sample size of 14 treated eyes and 12 control cases.
