摘要

息肉样脉络膜血管病变(Polypoidal choroidal vascular pathy, PCV)是新生血管性年龄相关性黄斑变性(nevascular degeneration, nAMD)的一种亚型,占亚洲新生血管性年龄相关性黄斑变性(nAMD)病例的50%。1 PCV复体包括息肉样病变(Polypoidal lesion, PL)和分支状新生血管网络(branching nevascular network, BNN),两者均位于视网膜色素上皮(RPE)和布鲁氏膜外层之间。因此,PCV应被认为是1型新生血管的一种变体。3此外,脉络膜背景的研究表明,PCV存在于厚脉络膜疾病谱中,其特征是脉络膜增厚、哈勒氏层血管扩张和覆盖的绒毛膜毛细血管衰减。4

Meeting polypoidal choroidal vasculopathy treatment needs halfway
Polypoidal choroidal vasculopathy (PCV) is a subtype of neovascular age-related macular degeneration (nAMD) that accounts for up to 50% of nAMD cases in Asia. 1 The PCV complex comprises polypoidal lesions (PL) and branching neovascular network (BNN), both of which are found between the retinal pigment epithelium (RPE) and the outer portion of Bruch’s membrane. 2 Hence, PCV should be considered a variant of type 1 neovascularization. 3 In addition, studies of the choroidal background suggest PCV resides within the pachychoroid spectrum of diseases, character-ized by choroidal thickening, dilated Haller’s layer vessels, and attenuation of the overlying choriocapillaris. 4
