In the OCT-A frame, a neovascular coralliform network is observed which emanates from the choroidal vasculature and extends to the sub-RPE space. Choroidal neovascularization (CNV) is part of the spectrum of exudative age-related macular degeneration (AMD) that consists of an abnormal growth of vessels from the choroidal vasculature to the ...

2018年9月15日 · The patient’s raster OCT shows subretinal fluid and apparent CNVM in the right eye and drusen and RPE disruption without subretinal fluid in the left. Treatment. OCT-A can be useful beyond diagnosis and may be integral to monitoring response to treatment.

Choroidal neovascular membranes (CNVM) can be described based on its location relative to the fovea, location relative to the retinal pigment epithelium, and fluorescein angiography findings. Location relative to the fovea: Subfoveal (underneath the fovea) Juxtafoveal (1-199 microns from the fovea) Extrafoveal (behind 200 microns from the fovea)

2025年1月1日 · Optical Coherence Tomography (OCT) is a non-invasive imaging technique used to visualize the retina and choroid, allowing for early detection and monitoring of CNVM. Advanced OCT features such as enhanced depth imaging (EDI) and swept-source OCT provide detailed visualization of the choroid, aiding in the accurate diagnosis of CNVM.

2023年5月21日 · Bridge arch-shaped SRF is an uncommon finding on OCT seen in eyes with subfoveal predominantly scarred variety of CNVM and is characterized by neurosensory detachment in a bow-shaped manner with a steep angle at the junction between the RPE and the sensory retina, and characterized by the presence of adhesion areas between the sensory retina ...

2019年4月1日 · Optical coherence tomography angiography (OCTA) is a novel imaging modality that allows noninvasive and rapid visualization of vascular plexuses at different depths, from the...

2020年11月24日 · OCT-A provides a reliable tool for detecting CNV in treatment naïve nAMD patients, with high sensitivity and specificity. Combined use of SD-OCT images and SHRM as an additional bio-marker,...

Guidelines for assessment of CNV include imaging the macula with optical coherence tomography (OCT) and fundus fluorescein angiography (FFA). 1 OCT is very sensitive at detecting changes in the macular structure and often findings may be suggestive of CNV.

2018年1月1日 · Discover how OCT angiography (OCTA) has revolutionized the management of age-related macular degeneration (AMD) and learn about its benefits in diagnosing choroidal neovascular membranes. Explore the limitations and potential advancements in this key technology for retina specialists.

2021年5月5日 · The appearance of CNVM complexes on ICG-A and OCT-A have recently been correlated, 4 and OCT-A may be an effective surrogate for monitoring subclinical CNVMs. More research is required to understand the pathophysiology of subclinical CNVMs, their biological role, and their relationship to exudative disease.
