Retinal Angiomatous Proliferation (RAP) was described by Yannuzzi and co-workers as a distinct form of neovascular Age-Related Degeneration (AMD). Disease RAP is a neovascularization that starts at the retina and progresses posteriorly into sub retinal space; eventually the neovascularization reaches the choroidal circulation and forms retinal ...

2022年11月21日 · PCV与CNV都是眼科常见疾病，但是两者有较大的区别，包括发病原因、临床表现、检查结果、预后等方面。

Other forms of CNV with ICG hot spots (occult CNV) and PCV are two important diagnoses that can be easily confounded with RAP. Small intraretinal hemorrhages, sometimes punctiform, in patients with soft drusen, are very typical in RAP, as are telangiectasias and RRA.

To identify the unique pathologic findings of retinal angiomatous proliferation (RAP) in optical coherence tomography (OCT). Retrospectively, 29 eyes of 25 patients with age-related macular degeneration and complicated RAP were analyzed. All 29 eyes ...

2010年10月29日 · All RAP lesions appeared as occult or minimally classic CNV on FA without clear evidence of pigment epithelium detachment (PED). We were able to identify five different patterns of RAP on the...

Stage 2 RAP is determined by the extension of IRN into the subretinal space, with or without PED. Stage 3 RAP has IRN and CNV connecting via retinochoroidal anastomosis. The definitive diagnosis of RAP is based on fundus examination, OCT, and angiographic findings.

2009年12月18日 · Natural history data surrounding RAP lesions are available through analysis of the eyes with subfoveal occult CNV within the placebo arm of the Verteporfin in Photodynamic Therapy (VIP) trial.

视网膜血管瘤样增生(retinal angiomatous proliferation，RAP)是与隐匿性脉络膜新生血管(CNV)相关的视网膜内毛细血管增生的一种特殊类型。 众所周知，老年性黄斑变性(age－related macular degeneration，AMD)是一种可严重影响中心视力的常见的视网膜变性类疾病，其发病率与 ...

choroidal neovascularization (CNV) is the initiating event of a RAP lesion rather than retinal neovascularization. Typically, this lesion begins as an occult CNV...
