What Researchers Did
Researchers conducted a review to evaluate various conservative pharmacologic and nonpharmacologic treatments proposed for acute nonarteritic central retinal artery occlusion (CRAO).
What They Found
The review found insufficient evidence to support the efficacy of any conservative pharmacologic or nonpharmacologic treatments for acute nonarteritic central retinal artery occlusion. The authors concluded that no current conservative treatment has been shown to influence the natural history of this disorder, and thrombolytic use remains controversial.
Canadian Relevance
This study has no direct Canadian connection as none of the authors or institutions are identified as Canadian.
Study Limitations
A key limitation of this review is the overall lack of high-quality evidence from primary studies regarding the efficacy of conservative treatments for CRAO.
