title: Ophthalmologic abnormalities in the hypereosinophilic syndrome.
abstract: Twelve patients with hypereosinophilic syndrome were studied to determine the frequency and type of eye involvement in this systemic disease. Four patients (33%) had visual symptoms, including blurred vision in one or both eyes, and one patient had an episode of complete blindness following cardiac surgery. Five patients (42%) had eye involvement by direct examination, and ten (83%) in fluorescent retinal angiograms. The principal defects noted were occlusions of major retinal vessels, choroidal infarct, and patchy or delayed choroidal filling. As these defects all occurred in patients with other severe systemic complications of the hypereosinophilic syndrome, including cardiologic disease, it is suggested that these lesions were the result of thromboembolic disease and that these patients should receive long-term anticoagulation. It was concluded that eye involvement is a frequent and important feature of the hypereosinophilic syndrome.
