case_images: Ocular exam. (A) Fundus photography. RE shows temporal optic disc pallor. LE shows a congestive disc with telangiectasies. (B) Electroretinogram. (C) Visual evoked potential pattern. Bilateral delay of conduction through the visual pathways is observed. (D) Fundus photography. Bilateral pallor of the optic discs remains. (E,F) Visual fields analysis. RE and LE show a paracentral and a cecocentral scotoma, respectively.

case_images: Anterior segment was normal in both eyes, and ocular fundus showed temporal optic disc pallor RE and a congestive disc with telangiectasies LE (Figure 1A). The electroretinogram study was normal and visual evoked potential study showed a bilateral delay of conduction through the visual pathways suggestive of bilateral optic neuropathy (Figures 1B,C). Fundoscopy revealed bilateral marked optic disc pallor (LE > RE) with an associate vascular attenuation (Figure 1D). However, bilateral pallor of the optic discs remains in the ocular fundus (Figures 1E,F).
