What Researchers Did
Researchers conducted a national survey among 45 US university-associated teaching hospitals to understand the acute management approaches for central retinal artery occlusion (CRAO).
What They Found
They found significant heterogeneity in CRAO treatment, with only 20% of institutions having a formal policy or guideline. Intravenous fibrinolysis was offered in 53% of institutions and preferred as initial treatment in 36%, while ocular massage was offered in 66% and anterior chamber paracentesis in 42%.
Canadian Relevance
This study was conducted in the US and has no direct Canadian connection, but its findings on treatment heterogeneity could be relevant to understanding potential variations in CRAO management within Canada.
Study Limitations
A limitation of this study is its reliance on self-reported data from a subset of US academic institutions, which may not reflect practices in all settings or other countries.
