case_images: Visual field (VF) 10-2 testing revealed mild scattered depressions bilaterally (OU) and a notable temporal paracentral scotoma OS (Figure 1A and B).
case_images: (A) Optical coherence tomography (OCT): OD slight disruption of nasal parafoveal outer photoreceptor segments and interdigitation zone. (B) Optical coherence tomography (OCT): OS focal atrophy and excavation of nasal parafoveal outer photoreceptor segments and interdigitation zone. Blue arrow: Outer nuclear layer; Red arrow: Photoreceptors; Green arrow: Outer plexiform layer.

case_images: Macular optical coherence tomography (OCT); (Figure 2) showed slight disruption of nasal parafoveal outer photoreceptor segments and interdigitation zone OD and focal atrophy and excavation of nasal parafoveal outer photoreceptor segments and interdigitation zone OS.
case_images: Visual evoked potential: Decreased amplitude with high contrast test stimuli OD and increased latency of high contrast test stimuli OS. Red color cells outside normative ranges. Green cells are within normative ranges.

case_images: Visual field 10-2 (VF) testing showed bilateral mild scattered VF depression and temporal scotoma in the left eye (Figure 4A and B).
case_images: (A) Optical coherence tomography (OCT) ganglion cell analysis: Normal macular profile OD. Significance mapping: Green is p>5%, yellow is p<5% and red is <1%. Thickness mapping: Blue 50 to ~ 80 microns, green >80 to ~180 microns, yellow >180 to <175 microns. (B) Optical coherence tomography (OCT) ganglion cell analysis: Atrophy of nasal papillary bundle OS. Significance mapping: Green is p>5%, yellow is p<5% and red is <1%. Thickness mapping: Blue 50 to ~ 80 microns, green >80 to ~180 microns, yellow >180 to <175 microns. (C) Optical coherence tomography (OCT) Full thickness analysis: Atrophy of nasal papillary bundle OS. Thickness mapping: Blue 50 to ~ 160 microns, green 200 to ~300 microns, yellow >300 to <370 microns. Deviation mapping: Red: ~25 to 40%, Orange: ~20 to 25%, yellow: -10 to 15%, green -5 to 5%, blue -25 to -15%, black and grey -30 to -50%. (D) Optical coherence tomography (OCT): OD 5 months follow up shows normal macular scan. (E) Optical coherence tomography (OCT): OS macular scan 5 months shows minimal improved architecture of ellipsoid zone, photoreceptor outer segments and interdigitation zone. Blue arrow: Outer nuclear layer; Red arrow: Photoreceptors; Green arrow: Outer plexiform layer.

case_images: Upon further investigation a notable disruption of nasal paracentral photoreceptors with overlying atrophied outer nuclear layer was found OS (Figure 5B and C) and normal thickness in OD (Figure 5A).   Repeat OD OCT macular scans remains unchanged (Figure 5D) and OS showed minimally improved architecture of ellipsoid zone, photoreceptor outer segments and interdigitation zone (Figure 5E).
