The topic is ophthalmic vascular manifestations(central retinal artery occlusion, central retinal vein occlusion, Purtscher’s retinopathy or retinal vasculitis) related to hypereosinophilia.
Study design: retrospective observational multi-centre
Inclusion criteria:
(i) at least one episode of ophthalmic vascular manifestation (CRAO, branch retinal artery occlusion (BRAO), CRVO, branch retinal vein occlusion (BRVO), Purtscher retinopathy, retinal vasculitis or ION);
(ii) concomitant absolute eosinophilia count (AEC) ≥ 0.5 x109 /L when the ophthalmic vascular manifestation occurred.
Exclusion criteria are: any condition, comorbidity or concomitant treatment leading to (constitutional or acquired) thrombophilia, cardiac embolism, rhythmic heart disease, tight carotid stenosis (NASCET ≥70%) homolateral to the retinal involvement or other causes of Purtscher’s retinopathy (e.g. acute pancreatitis, head trauma or thrombotic microangiopathy) or ION (e.g. giant cell arteritis).
