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. As only 20% of patients with RAO had a history of stroke, there is a discrepancy between CFD-studies and clinical observations. Mead et al. \[2\] postulated small emboli being washed into the cerebral arteries without causing clinical symptoms of stroke, whereas similar emboli being washed into the ophthalmic artery would cause RAO. There is a discrepancy between CFD-study results and clinical observations in RAO patients, indicating that there could be a high number of RAO-patients having had cerebral ischemies without symptoms of stroke (as postulated by Mead et al.\[2\]). Purpose of the present study is to evaluate hemodynamic pathological changes at the ophthalmic artery origin in patients with RAO detected with an already existing CFD-model
