摘要穹顶样黄斑(DSM)多表现为高度近视眼后巩膜葡萄肿区域内黄斑区向内隆起。依据光学相干断层扫描成像检查结果，DSM被分为垂直型、水平型和圆型，但其形成机制仍存在争议。DSM最初被认为与低眼压及玻璃体黄斑牵拉等有关。越来越多的研究支持DSM是为抵抗近视进展而形成的一种适应性保护机制。但最新研究表明，黄斑隆起可能是其周围区域进行性不对称的脉络膜及巩膜变薄所致，而不是黄斑中心区主动向内隆起的结果。高度近视眼DSM中常伴随多种近视性并发症，导致DSM患眼视力下降及视功能损伤，如浆液性视网膜脱离、视网膜劈裂、脉络膜新生血管、黄斑裂孔及Bruch膜缺损等。DSM与近视性并发症的因果关系尚不明确，且针对相关并发症仍无有效预防及治疗方法。本文对高度近视眼DSM形成机制及其与近视性并发症的关系进行总结，为探索高度近视的视觉预后及DSM的发病机制提供理论依据。

abstractsDome-shaped macula (DSM) mostly presents as an inward bulging of the macular area within the area of posterior staphyloma in highly myopic eyes.According to the optical coherence tomography results, DSM has been classified as vertical, horizontal and round type, but its formation mechanism is still controversial.The appearance of DSM was initially thought to be associated with low intraocular pressure and vitreous macular traction.There is growing support that DSM is an adaptive protective mechanism developed to resist the progression of myopia.However, recent studies suggest that the macular bulge may be the result of progressive asymmetric choroidal and scleral thinning in the surrounding area, rather than active inward bulging of the central macula.In addition, DSM in highly myopic eyes is often accompanied by a variety of myopic complications that lead to decreased visual acuity and visual impairment in the eye with DSM, such as serous retinal detachment, retinoschisis, choroidal neovascularization, macular hole and Bruch membrane defects.However, the causal relationship between DSM and myopic complications is unclear, and there are still no effective preventive measures or treatments for related complications.This article summarizes the mechanism of DSM formation in highly myopic eyes and its association with myopic complications to provide a theoretical basis for exploring the visual prognosis of patients with high myopia and the pathogenesis of DSM.
