Fig. 2.

Indocyanine green angiograms (ICGA) of the right eye. A: Choroidal venous phase shows dilated choroidal veins (yellow arrows) and their branches that collected blood from the macular, superonasal, and inferotemporal areas. The vessels flow out (orange arrowhead) at the entry site of the short posterior ciliary arteriy shown in Fig. 2B (orange arrowhead), together with a very short choroidal vein running from the superotemporal area. Leakage from those vessels is not seen. B: Magnified ICGA image at choroidal arterial phase. Arrowheads indicate entry sites of posterior ciliary arteries. A faint silhouette of the dilated choroidal vein (yellow arrows) running from the macular area is seen. C: Magnified ICGA image of the enclosed area in Fig. 2A. On the widest part of the large choroidal vein, several twigs (red bracket) that eventually joined the dilated choroidal vein through a branch (red arrowheads) are observed. D: Ultra-widefield ICGA shows one vortex vein at the equator in the inferotemporal and inferonasal quadrants and two vortex veins in superotemporal and superonasal quadrants with and without forming an ampulla (asterisk). The large choroidal vein (black arrow) collecting blood in the nasal quadrants runs toward the superotemporal quadrant over the supraoptic disc area. Yellow arrows point to the dilated choroidal veins seen in Fig. 2A. The choroidal venous flow from the posterior part toward the vortex vein in the superotemporal quadrant is less organized than those in the other 3 quadrants. There is a relatively broad area showing hypofluorescence (black arrowheads). A polypoidal structure (p), corresponding to the reddish- orange lesion (“p” in Fig. 1A) is seen along a choroidal vein.
