[Hypereosinophilic syndrome with ocular involvement].

The authors report a case of idiopathic hypereosinophilia with Löffler endocarditis in a 19 year old male. Retinal arteriolar occlusions were observed in the pre-equatorial region and documented by angiography. Histologic examination of the globes showed obliteration of the arterioles by a fibrinous coagulum without signs of vasculitis. Clinical data appears to suggest an embolic origin of the occlusions rather than thrombosis in situ.
