Methodology: 4/5
Usefulness: 3/5

 

Question and Methods: This was a Multicenter, double-blind, double-dummy phase 3 RCT (n=78) comparing IV tenecteplase 0.25 mg/kg vs oral aspirin 300 mg within 4.5 hours in non-arteritic CRAO.

Findings: Vision recovery at 30 days (BCVA ≤0.7 logMAR): 20% (8/40) tenecteplase vs 24% (9/38) aspirin; risk difference −3.7%, P=0.69.

Limitations: Small sample size limits power for modest benefit; symptom onset time was patient-reported, and off-chart acuity conversions add measurement imprecision. 

Interpretation: Tenecteplase did not improve recovery vs aspirin and had more serious adverse events, including one fatal symptomatic intracranial hemorrhage; routine use not supported.
