视盘周围脉络膜增厚综合征(PPS)是以视盘附近区域脉络膜增厚为特征的厚脉络膜谱系疾病之一,好发于中老年男性,部分患眼具有远视眼和短眼轴的特点。PPS的诊断和鉴别主要依靠其影像学特点。PPS光学相干断层扫描表现为黄斑鼻侧脉络膜大血管显著扩张,对应位置出现视网膜内积液等改变和视网膜色素上皮的改变等,吲哚菁绿眼底血管造影可见视盘周围大血管扩张伴通透性增强。PPS需与葡萄膜渗漏综合征、中心浆液性脉络膜视网膜病变和肥厚性脉络膜新生血管性病变等疾病相鉴别。光动力治疗或可改善PPS患者的视网膜积液。目前PPS的相关研究仍处于初步阶段,其是否可作为一独立疾病仍有争议,治疗有效性需经前瞻性对照研究验证。本文就PPS的临床特点、发病机制、影像学表现、诊断、鉴别诊断及治疗进行总结和展望,未来需进一步的研究为PPS的定义、诊断、治疗和发病机制提供新见解。
Peripapillary pachychoroid syndrome (PPS), a new entity in pachychoroid disease spectrum, is characterized by the thickening of the choroid in the peripapillary area.PPS is more likely to occur in middle-aged and older males, and some of the affected eyes are hyperopic and have short axial lengths.The diagnosis and differentiation of PPS depends mainly on the imaging characteristics.Optical coherence tomography shows that dilated Haller layer vessels are located in the nasal macula and associated with intraretinal fluid in the corresponding locations.Indocyanine green angiography shows dilated large choroidal vessels and choroidal hyperpermeability in the nasal maculal and peripapillary region.PPS should be differentiated from uveal effusion syndrome, central serous chorioretinopathy, and pachychoroid neovascularization.Photodynamic therapy may improve retinal effusion in patients with PPS.At present, the research on PPS is insufficient.It is still controversial whether PPS can be considered as a separate entity.The effectiveness of treatment needs more prospective studies.Further research is needed to provide new insights into the definition, diagnosis, treatment and pathogenesis of PPS.
