摘　　要：脉络膜新生血管(CNV)是由于脉络膜异常继发增殖的新生血管,常见于年龄相关性黄斑变性、近视性CNV、息肉状脉络膜血管病变等疾病,是导致视力损害的主要原因之一。不同类型CNV血管形态和血流灌注的特征均存在一定差异和特征,包括新生血管走形、血流灌注、黄斑中心凹无血管区面积等方面。了解不同类型CNV不同分层的新生血管形态和血流学特征,为临床医师运用眼科影像学图像精准诊断、分类CNV以及制定更好的诊疗方案提供依据。笔者就不同类型CNV形态学与血流学特征作一综述。Choroidal neovascularization(CNV)refers to the formation of new blood vessels stemming from the choroidal layer,a phenomenon commonly observed in conditions such as age-related macular degeneration,myopic CNV,and polypoid choroidal vasculopathy.These abnormal vessels contribute significantly to visual impairment.Variations exist in the morphology and blood perfusion characteristics of different types of CNV,including differences in neovascular shape,blood flow patterns,and the extent of avascular zones in the macular fovea.Understanding these variations across different layers is crucial for clinicians to accurately diagnose,classify,and develop treatment plans using ophthalmic imaging.This article provides a comprehensive review of the morphological and hematological characteristics of various CNV types.
