Fundus photograph of the right and left eyes. (A) Wide field color fundus photograph of the right eye: blurred optic disc margin. (B) Wide field color fundus photograph of the left eye: well-defined area of whitening involving the peripheral superonasal quadrant with slight haziness extending from that area up to the upper margin of disc and upper temporal arcade. The disc margin is ill-defined.

Fig1
The macula and vessels showed no visible abnormalities in either eye (Figure 1A,B).
Fluorescein angiography of the left and right eyes. (A) Fluorescein angiography of the left eye: early hyperfluorescence corresponding to the area of retinal whitening and haziness. (B) Fluorescein angiography of the left eye: late frame shows perivascular leakage in the same area (vasculitis) together with late hyperfluorescence of the disc. (C) Fluorescein angiography of the right eye: late hyperfluorescence and leakage from the disc.

Fig2
Fluorescein angiography showed hyperfluorescence corresponding to the peripheral whitening with perivascular leakage in the left eye and optic disc leakage in both eyes (Figure 2A,B,C).
B-scan ultrasound of the right and left eyes. (A) B-scan ultrasound of the right eye: elevation of optic nerve head. (B) B-scan ultrasound of the left eye: no visible elevation could be appreciated in the superonasal quadrant of the left eye.

Fig3
B-scan of the superonasal quadrant did not reveal a corresponding elevation or abnormality (Figure 3A,B).
OCT of the lesion: irregular retinal contour with areas of retinal elevation. The individual retinal layers could not be distinguished due to infiltration with multiple hyperreflective dots. Diffuse thickening at the retinal nerve fiber layer. Irregular vitreo-retinal interface with traction by partial PVD together with moderate hyperreflective dots in the vitreous.

OCT of the lesion revealed retinal infiltration with hyperreflective dots (Figure 4).
