视网膜大动脉瘤(RAM)是一种获得性视网膜血管异常疾病。其发病机制尚未明确，与高血压、动脉硬化、高血脂等全身情况有关。视网膜大动脉瘤由于管壁薄弱高血压情况下易发生渗出或出血引发其他并发症，临床表现复杂多样，不易诊断。瘤体本身有自行退化倾向，病变未累及黄斑区者视力预后良好。但当渗出和/或出血累及黄斑时，严重影响视力，需一些可行性方案治疗。了解视网膜大动脉瘤的典型影像学表现，有助于明确诊断并给予相应的治疗措施。本文主要综述了多种检查方式下视网膜大动脉瘤的表现及不同类型视网膜大动脉瘤对应的多种治疗方案，旨在为未来早期诊断和治疗视网膜大动脉瘤提供参考。

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.
