indocyanine green angiography

indocyanine green angiography

a test for studying choroidal vasculature by which indocyanine green dye, which absorbs infrared light at 805 nm and emits at 835 nm, is injected intravenously and photographed as it flows through the retinal and choroidal vessels.

Indocyanine green angiography (ICGA) can visualise the choroidal vasculature, but as with FA, due to its invasive nature it might be complemented in the future by OCT-A.
Moreover, this setup has the advantage of being used to capture multimodal images such as fundus autofluorescence, infra-red imaging, SD-OCT, fluorescein and indocyanine green angiography.1,2,14 Also, the peripheral changes can be viewed by capturing 55Adeg images using different lens attachments.
Indocyanine green angiography (ICGA) is shown to be superior to fundus fluorescein angiography (FFA) for detailed imaging of choroid neovascularization (CNV) and diagnosis of choroidal polyps.
However, there were no abnormalities found in the fluorescein angiography, indocyanine green angiography, or FAF images.
If the diagnosis of CNV could not be confirmed by SD-OCT (hyperreflective area above the damaged retinal pigment epithelial level with intraretinal fluid/increased foveal thickness and/or serous foveal detachment), FFA and indocyanine green angiography (ICGA) (Spectralis HRA + OCT, Heidelberg Engineering, Heidelberg, Germany) were performed.
Indocyanine green angiography of the deeper choroidal vasculature is useful to differentiate choroidal haemangioma from a metastatic deposit.
The diagnosis of PCV was based on indocyanine green angiography (ICGA) results, which showed a branching vascular network (BVN) that terminated in aneurysmal enlargements, that is, polypoidal lesions.[sup][5],[31] Exclusion criteria included patients with concomitant ocular disease, such as uveitis or proliferative diabetic retinopathy, or those receiving other treatments, such as PDT, laser, and intraocular surgery, within 3 months before the first intravitreal conbercept (IVC) treatment or during the 1-year treatment period.
Among the topics are color vision and color blindness, slit-lamp examination, corneal confocal microscopy, optic disc assessment in glaucoma, indocyanine green angiography, A-scan and B-scan ultrasonography, electrophysical tests for assessing visual function, anterior segment optical coherence tomography, localizing an intra-ocular foreign body, diagnostic procedures for genetically transmitted eye diseases, diagnostic modalities in intra-ocular malignancies, and ocular motor nerve palsies.
Patients were recruited into the study if they were over the age of 50 and were confirmed to have NvAMD from initial clinician examination and baseline imaging which included conventional fluorescein and indocyanine green angiography at the point of referral.
Fluorescein angiography and indocyanine green angiography were unremarkable bilaterally.
The Zeiss Pentero microscope in the SGH iMRI operating theatre has inbuilt fluorescent technologies that facilitate intraoperative near-infrared indocyanine green angiography. This has been shown to be useful for cerebral arteriovenous malformation surgery (14-16), enabling the identification of residual AVMs.
