入选标准

  • Patients aged up to 18 years
  • CRAO diagnosis by fundoscopic examination or non-mydriatic retinophotography (NMR) performed by an ophthalmologist.
  • Blindness defined according to WHO classification as visual acuity <1/20 (20/400).
  • Treatment intervention should be initiated by a stroke team as quickly as possible and within 4.5 hours from symptom onset.
  • No clinical (e.g headache with jaw claudication or scalp tenderness, no temporal pulse) or laboratory evidence (elevated CRP) of giant cell arteritis
  • No clinical or radiological evidence of stroke within the last 3 months.
  • Patients covered by health care insurance (social security)
  • Written informed consent obtained.

排除标准

  • Symptoms onset more than 4.5 h prior to infusion start or undetermined time of symptom onset.
  • Minor VA deficit or VA rapidly improving before start of infusion.
  • CRAO without foveal ischemia.
  • Other retinal vascular disease: occlusion of branch of the CRA without significant VA loss, occlusion of the retinal vein, proliferative diabetic retinopathy or any other severe retinopathy.
  • Clinical or laboratory evidence of temporal arteritis.
  • Evidence of ICH or ischemic stroke on the pre-administration CT scan or MRI.
  • Pregnant or lactating women
  • Adults under guardianship or trusteeship
  • Any contraindication to alteplase
  • Any contraindication to aspirin
