Functional recovery to best corrected visual acuity (BCVA) of Logarithm of the Minimum Angle of Resolution (LogMAR) ≤ 0.5 (normal to mild vision impairment according to WHO ICD-11 (WHO, 2019)) in the affected eye at Visit (V) 3 (30 ± 5 days), dichotomized ITT analysis (functional recovery to LogMAR ≤ 0.5 vs. no functional recovery, i.e., LogMAR > 0.5) |

E.3 | Principal inclusion criteria |
● Age ≥ 18 years ● Acute non-arteritic CRAO (i.e. sudden, painless monocular vision loss) ≤ 12 hours after symptom onset confirmed by an experienced ophthalmologist through assessment of: BCVA, intraocular pressure, swinging flash light test (relative afferent pupil defect), slit-lamp biomicroscopy, fundoscopy, and OCT of the macula of both eyes* (*within the 4.5-hour time window: to be skipped if not feasible ≤ 10 minutes; beyond the 4.5-hour time window: mandatory) ● BCVA of LogMAR ≥ 1.3 in the affected eye (functional blindness according to WHO ICD-11) ● Reading must have been possible with the affected eye before CRAO (LogMAR ≤ 0.5) ● Neurological examination performed by an experienced stroke neurologist ● Brain imaging as per local standard for acute retinal ischemia/stroke assessment, either cranial computed tomography (CT) or cranial magnetic resonance imaging (MRI) Additional inclusion criteria for interventional study: ● Initiation of study treatment (IVT or placebo) by an experienced stroke neurologist within ≤ 4.5 hours of certain symptom onset ● Written informed consent (interventional study) given by the patient Additional inclusion criteria for observational study: ● Participation of patients within ≤ 4.5 hours of symptom onset is only allowed in case of contraindication(s) for IVT of contraindication(s) for IVT or history of hypersensitivity to Acitlyse® or in case of pregnancy or laction ● Written informed consent (observational study) given by the patient
