(a) Radial iridian vascular engorgement at 5 to 7 o'clock location in RE. (b, c) Gonioscopic examination shows a graded IV open angle with a vascular racemose net of 360 degrees in the iridocorneal angle.

The vessels seem to originate from the iris stroma and then extended circumferentially (Figure 1(a)). Gonioscopic examination showed a graded IV open angle with a vascular racemose net of 360 degrees in the iridocorneal angle (Figures 1(b) and 1(c)).
RE ocular fundus shows an oblique papilla and myopic coriorretinitis without other findings.

Ocular fundus showed in the RE an oblique papilla, myopic coriorretinitis, without exudates, hemorrhages, or neovascularization (Figure 2).
RE anterior segment optic coherence tomography shows intrastromal hyporeflective spaces corresponding to the iris vessels.

(a, b) RE fluorescein angiography shows an early filling of the vessels without contrast diffusion in the iris, angle, and retina vessels.

For the differential diagnosis between neovascularization and tumor/vascular malformation, a fluorescein angiography (FA) was performed and normal contrast uptake was demonstrated without extravasation of the latter at the level of the iridian, iridocorneal angle, and retinal vessels (Figures 4(a) and 4 (b)).
