Scattered dotted hyperfluorescence and presence of microangioma were determined as stage II.
Comparatively, in 'occult' CNV the new vessels lie underneath the RPE and images show diffuse hyperfluorescence at a later stage of the FA.
As opposed to fundus fluorescein angiography (FFA), in which layers other than the superficial vascular plexus appear only as background hyperfluorescence, OCTA enables separate imaging of the superficial and deep vascular layers and the choroidal vessels.
1] Fluorescein angiography of a metastatic deposit reveals hypofluoresence in the arterial phase followed by late hyperfluorescence, with no pooling of dye.
There was widespread hyperfluorescence with leakage around the optic disc in the edema group on day 1 compared to the control group.
Objective: The overall goal of the HyperOLED project is to develop materials and matching device architectures for high-performance, hyperfluorescence organic light emitting diodes (OLEDs) for use in display applications and solid state lighting.
FFA showed early hyperfluorescence, which increased in intensity with no increase in size, which faded away in the late phase suggestive of window defect (Figure 3).
In fluorescein angiography delayed circulation, hyperfluorescence due to the breakdown of the blood-retinal barrier, venous tortuosity, and blockage due to retinal hemorrhages were obvious (Figure 2).
Fundus angiography exhibits hypofluorescence in early stages and hyperfluorescence in later stages.
Furthermore, optical coherence tomography (OCT) confirmed the presence of bilateral subretinal fluid (Figure 1b), and fluorescein angiography (FA) demonstrated early pinpoint areas of hyperfluorescence with a "starry sky" appearance and optic disc staining (Figure 2a).
Fluorescein angiography showed hyperfluorescence of the optic discs (Fig.
A fluorescein angiograph of the retina showed knobby hyperfluorescence of the retinal arterioles with minimal leakage, as well as some spots of leakage at the level of the retinal pigment epithelium.
