[Clinical diagnostics and therapy for non-arteritic central retinal artery occlusion]

Abstract

Central retinal artery occlusion (CRAO) is an ophthalmological emergency situation. Known risk factors are arterial hypertension, cardial arrhythmia, arteriosclerosis, hypercholesterolemia and diabetes. Elderly patients should be examined for an arteritic genesis. Young patients (< 45 years) without typical risk factors may suffer from thrombophilia. There is no uniform recommendation on how to treat non-arteritic CRAO. Many different interventions have been suggested in the literature, i. e., massaging the eye, systemic or local reduction of intraocular pressure, anticoagulation, either systemically administered venous thrombolysis or supraselective intra-arterial thrombolysis. In this review we present the causes of CRAO and diagnostic means to detect causes; we also critically discuss previously described therapeutic options. It is our aim to provide a guide through the necessary interdisciplinary diagnostics in co-operation with internal medicine and neurology and to recommend a multimodal therapy in patients with non-arteritic CRAO.
