Retinal Artery Occlusion
Reconstruction of Pathological Changes of the Ophthalmic Artery in Patients With Retinal Artery Occlusion
Retinal artery occlusions (RAO) cause deterioration in visual acuity and visual fields. In computational fluid dynamics (CFD) studies [1] 10% of ascending emboli caused RAO, the residual 90% embolized into the cerebral arteries.

- NCT02679716
- Testing
- MRI of the cerebral arteries
