Abstract:Central retinal artery occlusion(CRAO)refers to occlusion of the central retinal artery(CRA), which acts as the primary blood supply to the inner neurosensory retina, and leads to an acute loss of vision and permanent visual disability. The natural history of visual prognosis in CRAO is generally poor. Despite a variety of treatment options have been studied, such as ocular massage, anterior chamber paracentesis, hyperbaric oxygen therapy(HBOT)and intra-arterial infusion of tissue plasminogen activator(tPA), but there is currently no evidence-based management strategies for the treatment of CRAO. Furthermore, the efficacy of all available managements is debatable and many have uncertain risks. This review will offer a summary of the currently known treatment options for CRAO and probe into their safety and efficacy on the prognosis of CRAO.
