Fundus examination in RE showed optic disc pallor with obliteration of cup and sheathing of vessels around the disc suggesting secondary optic atrophy (Figure 1A (Fig. 1)) with arteriolar attenuation and arterio-venous (A-V) crossing changes. Fundus examination of LE showed pallid disc edema with flame-shaped retinal haemorrhages in the peri-papillary region, attenuation of the retinal arterioles, and arterio-venous crossing changes without any background diabetic retinopathy (Figure 1B (Fig. 1)).
Fundus fluorescein angiography (FFA) of LE showing delayed filling of the disc especially superior part in the early phase, irregular filling of retinal arterioles and staining of the disc in the late phase.
