Fundus photos (a) at initial presentation demonstrating mild temporal pallor more obvious in the left eye. Optical coherence tomography (OCT) of the retinal nerve fiber layer (b) showed a normal average thickness in both eyes. Humphrey 24-2 SITA-Fast visual fields (c) showed central scotomas in both eyes. The stimulus size was III and mean deviation was -10.49dB OD and -7.55dB OS. The visual field index was 76% OD and 79% OS. OCT of the macular ganglion cell-inner plexiform layer (d) did not show any significant abnormalities and there was a left segmentation error.

Humphrey visual field testing demonstrated central scotomas in both eyes (Fig. 1).
At final follow-up 24 months after initial presentation, Humphrey 24-2 SITA-Fast visual fields (a) showed less dense central scotoma. The stimulus size was III and mean deviation was -8.69dB OD and -6.22dB OS. The visual field index was 88% OD and 89% OS. OCT of the retinal nerve fiber layer (b) showed temporal thinning in both eyes and there was diffuse thinning in the ganglion cell layer-inner plexiform layer (c).

Humphrey visual field testing demonstrated bilateral central scotomas and OCT retinal nerve fiber layer (RNFL) showed interval thinning of the temporal portion of the optic nerve (Fig. 2).
