Retinal arterial macroaneurysm(RAM)is a kind of acquired retinal vascular disorder. The pathogenesis of RAM is not yet clear, and it is associated with some systemic conditions, including hypertension, arteriosclerosis and hyperlipidemia. RAM is prone to exudation or bleeding, leading to some other complications in the condition of hypertension due to the weak tube wall, and its clinical manifestations are complex and diverse, which makes it difficult to diagnose. RAM itself has a tendency of self-degeneration, and the prognosis of visual acuity is good if the lesion doesn't involve the macular area. However, when the macula is affected by exudation and/or bleeding, the vision is severely affected and some feasible treatments are needed. Understanding the typical imaging manifestations of RAM is helpful to make a definite diagnosis and give corresponding treatment measures. In this paper, the manifestations of RAM by various examination methods are reviewed and the corresponding treatments of different types of RAM are summarized, aiming to provide reference for the early diagnosis and treatment of RAM in the future.
