Diagnostic usefulness of indocyanine green angiography (ICGA ... - AMD …
Indocyanine green angiography (ICGA) is useful for the study of occult CNV (OCNV), and particularly in identifying the characteristic patterns of idiopathic polypoidal choroidal vasculopathy (IPCV) and retinal angiomatous proliferation (RAP). It is important to correctly diagnose these disorders, since they respond differently to treatment.
Wet Age-Related Macular Degeneration (AMD) - StatPearls - NCBI Bookshelf
2024年8月11日 · Wet age-related macular degeneration (AMD), also known as exudative or neovascular AMD, primarily affects the macula and is the most common cause of central visual impairment and blindness among older individuals in developed countries.[2]
Indocyanine Green (ICG) Angiography - StatPearls - NCBI Bookshelf
2023年8月25日 · ICGA helps to delineate the extent of occult CNVM. Occult CNVM comprises 60-85% of CNV in wet AMD. In ICGA, three morphologic variants of CNVM have been described: hot spot or focal spot, plaque (poorly defined or well defined), and mixed or combined (both hot spot and plaque are present).
黄斑疾病——5、年龄相关性黄斑变性 - 知乎 - 知乎专栏
年龄相关性黄斑变性(AMD)是一种发病率与年龄增长明显相关的 黄斑区视网膜变性 类疾病。 AMD的确切发病机制不详,目前认为,光损伤、遗传背景、女性、白种人、吸烟等因素为发病的危险因素。 2、诊断要点. 尽管AMD是临床上常见的致盲性眼病,相关的各种研究日新月异,但在临床诊断方面并无明确的,一致性的认识。 文献中所应用的很多诊断标准多适用于流行病学研究和临床科研,并非都适用于日常的临床工作。 在这儿,彭老师提出的诊断要点仅作为临床实践中 …

2024年11月11日 · 本研究探讨了利用 深度学习 技术,尤其是生成对抗网络(GANs),将彩色眼底照片(CF)转换为吲哚菁绿血管造影(ICGA)图像以辅助年龄 相关性 黄斑变性(AMD)的筛查的可能性。 随着人口老龄化的加剧,AMD成为一大公共卫生问题,尤其是其湿性形式,它涉及脉络膜新生血管(CNV)的形成,可能导致黄斑区域出血和严重的视力损害。 虽然ICGA是检测此类病变的黄金标准,但由于其侵入性和潜在风险,限制了其在常规筛查中的应用。 相反,CF …
Optical Coherence Tomography Angiography in AMD
Due to a superior visualization of polyps and branching vascular network (BVN), ICGA has long been the gold standard for the diagnosis of polypoidal choroidal vasculopathy (PCV). Previous studies have shown that OCTA is comparable to ICGA for the detection of the BVN, often showing it with even greater detail than ICGA.
