2015年4月1日 · CNV. Choroidal neovascularization is frequently associated with lacquer cracks or areas of RPE atrophy. CNV has been reported to affect up to 10 to 15 percent of eyes with an axial length greater than 26.5 mm and is a major cause of …

The type 2 CNV is visualized as a neovascular network that grows from the choroid vasculature and traverses the RPE-Bruch's membrane complex into the subretinal space. Type 3 CNV is clinically seen as tiny intra- and subretinal hemorrhages that correlate on OCTA as an intraretinal anastomosis originating in the deep capillary plexus of the retina.

2020年3月1日 · A diagnosis of myopic CNV should be considered for a middle-aged myope who presents with sudden vision loss, metamorphopsia, and typi­cal funduscopic changes. Establishing a diagnosis in an elderly patient is more challenging because other conditions that can lead to CNV, such as age-related macular degeneration (AMD), may be present.

2006年9月6日 · Colour fundus photographs, fundus fluorescein angiograms (FFA) and fundus autofluorescence images were obtained from a group of 40 patients (43 eyes) with age‐related macular degeneration and purely classic or occult CNV. Only patients with newly diagnosed CNV and in whom autofluorescence images were obtained within 2 weeks from FFA were included.

2019年3月8日 · To identify local risk factors for development of CNV, we analyzed fundus findings of multimodal imaging at the time of CSC diagnosis in Group 1 prior to the onset of secondary...

2015年1月23日 · A color fundus photograph (a) shows patches of chorioretinal atrophy in a high-myopic fundus without any subretinal hemorrhage or choroidal neovascular membrane (CNV). Early phase of fluorescein angiography (b) shows early hyperfluorescence (arrow) with diffuse leakage (arrow) in the late phase of fluorescein angiography (c).

2018年3月1日 · Fundus autofluorescence images can be used to detect macular atrophy in patients treated for myopic CNV with no recurrence. Representative case with myopic CNV before (A–C) and 3 months after (D–F) treatment with intravitreal ranibizumab at baseline.

The standard tests for diagnosing myopic CNV are fundus biomicroscopy, fluorescein angiography (FA) and optical coherence tomography (OCT). FA and OCT are generally recommended baseline diagnostic tests for myopic CNV in conjunction with colour photos and clinical examination.

2017年11月1日 · In 2008, Sawa et al 63 proposed a classification for the development of myopic CNV based on fundus autofluorescence (FAF) patterns in eyes with myopic CNV. This technique also allows detection of CNV-related macular atrophy, which helps to determine the long-term visual outcomes of myopic CNV.

The progression of myopic CNV evolves through three main stages. In the initial phase, there is direct damage to the photoreceptors, causing central visual loss. Then, as the CNV regresses, a fibrous pigmented scar is formed. Finally, chorioretinal atrophy develops around the regressed CNV, which results in a poor long term visual outcome ...
