Advances in the treatment and prevention of acute retinal arterial ischemia

Abstract

Acute transient or permanent retinal arterial ischemia is ocular and systemic emergency requiring immediate diagnosis and treatment. Transient monocular vision loss is transient retinal arterial ischemia which leaves no permanent deficits. Central retinal arterial occlusion and branch retinal arterial occlusion lead to permanent visual function deficits in the majority of patients. Current treatment include lowering intraocular pressure, dilating blood vessels, hyperbaric oxygen therapy, intravenous or intra-arterial thrombolysis and so on, but there is still no standard treatment procedure. High risk groups should receive primary prevention measures in order to reduce the incidence of the disease. Patients with acute retinal arterial ischemia are at high risk of subsequent stroke and adverse cardiovascular events. Relevant risk factors should be identified in time, the primary disease should be treated actively, and appropriate secondary prevention measures should be taken to improve the prognosis. This review summarizes the recent treatment and prevention procedures of acute retinal arterial ischemia, to provide references for the management of these diseases.
