BACKGROUND Protein Z is a glycoprotein that acts as a co-factor for the inhibition of activated coagulation factor X. Protein Z circulating in abnormal levels has been associated with increased risk for acute ischemic events. Non-arteritic Anterior Ischemic Optic Neuropathy (N-AION) is caused by acute ischemic infarction of the optic nerve head, supplied by the posterior ciliary arteries. OBJ...

We present the case of a 45-year-old male patient with sudden painless visual loss in left eye (OS), diagnosed as nonarteritic anterior ischemic optic neuropathy (NAION). Three months later, new superior scotoma, accompanied by an inferior disc edema, characterized recurrent episode NAION OS. Ambulatory blood pressure monitoring disclosed arterial hypertension, no drop during sleep. Optical Coh...

BACKGROUND Patients with retinal vascular occlusion disease have an increased risk for ischemic stroke and share some risk factors with cerebrovascular disease. The purpose of this study was to analyze the prevalence of atrial fibrillation (AF) in subjects with retinal vascular occlusive disease and anterior ischemic optic neuropathy and to compare these data to an ischemic stroke group.
