视网膜血管瘤样增生的诊断与治疗

Diagnosis and treatment for retinal angiomatous proliferation

视网膜血管瘤样增生(retinal angiomatous proliferation,RAP)是湿性老年性黄斑变性(age-related macular degeneration,AMD)隐匿性新生血管的另一种病变形式,起源于黄斑旁视网膜深层毛细血管层,以多发性小灶状视网膜内出血、视网膜色素上皮脱离(pigment epithelial detachment,PED)、视网膜-脉络膜血管吻合(retinal-choroidal anastomosis,RCA)为特点,对视力损害严重。本文对近年来的有关文献进行复习,并就RAP的发病机制、临床分期、诊断特点、治疗及预后进行综述。

Retinal angiomatous proliferation （RAP） is the other pathological pattern of wet age-related macular degeneration （AMD）, which is originated from deep retinal focal intraretinal hemorrhage, pigment epithelial detachment and retinal-choroidal anastomosis （RCA）. It can impair visual acuity severely. The pathogenesis, clinical stages, diagnosis features, treatment and prognosis were reviewed in this article.
