Unlike fluorescein angiography, which uses intravenous dye and has long been the standard technique to image retinal blood vessels, OCTA is non-invasive - it does not require an intravenous dye. (neec.com)
Fluorescein angiography (FA) shows a delay in filling of the retinal arteries. (retinaoc.com)
Angiography using sodium fluorescein dye is commonly performed when signs of AMD are observed and and particularly when exudative changes are suspected. (org.es)
Fluorescein angiography was performed to detect the area with CNV, and the evaluation was made by computerized measurement of digital images. (arvojournals.org)
Today, SD-OCT and noninvasive fundus autofluorescence imaging can provide additional anatomical information beyond the fluorescein angiography (FA), including visualization of the layers of the retina and choroid involved with the neovascular membrane. (amdbook.org)
Ophthalmic testing-including fundus photography, intravenous fluorescein angiography, optical coherence tomography, fundus autofluorescence imaging-play a significant role in our ability to diagnose and treat patients. (eye-pix.com)
Retinal1
By comparing repeated OCT scans from a retinal location, changes in signal due to blood cell movement can be used to create blood vessel maps (OCT angiograms). (neec.com)
Choroidal3
Because of its protein-binding properties, its leakage from choriocapillaries is less and thus it will remain longer in choroidal vessels compared to fluorescein dye. (wikipedia.org)
Here is an example of various en-face OCT scans through various layers of the choroidal vasculature in a normal eye, taken with a prototype SS-OCT device at NEEC. (neec.com)
Patients without these findings must have diffuse choroidal thickening-as seen using ultrasonography-with fluorescein angiographic abnormalities, including focal areas of delayed choroidal perfusion, multifocal pinpoint leakage, areas of placoid hyperfluorescence, pooling of subretinal fluid, and optic nerve staining.

Injection2
The evolution after treatment was satisfactory, the visual acuity 3 weeks after the intravenous injection of corticoids increased to 2/10. (bvsalud.org)
The compound is given by intravenous injection to do POSITRON-EMISSION TOMOGRAPHY for the assessment of cerebral and myocardial glucose metabolism in various physiological or pathological states including stroke and myocardial ischemia. (lookformedical.com)
Patient1
Patient received 3 days of intravenous methylprednisolone at 10mg/kg/D for 3 days in a row and an oral relay was started with a progressive degression over 2 weeks. (bvsalud.org)
Blood2
Such dyes help highlight blood vessels and are usually injected through an intravenous (IV) line. (medicalhealthtests.com)
Angiogram: a medical imaging test used to visualize blood vessels in the body. (drpaulkilgore.com)
Green1
Fluorescein and indocyanine green angiograms showed no sign of activity or presence of neovessels.A complete metabolic work-up, mainly phosphocalcic, was ordered again and the systemic diagnosis of articular chondrocalcinosis was retained. (bvsalud.org)
