"There are no evidence based therapies that have demonstrated efficacy in improving visual outcomes, and a meta-study has suggested that some therapies may be worse than the natural course" per EyeWiki.
"Clot busting tissue plasminogen activator (tPA) was evaluated in the EAGLE study...did not recommend intra-arterial tPA for acute CRAO because of significant symptomatic intracranial hemorrhage without evidence of visual benefit" per American Academy of Ophthalmology's EyeWiki.
