case_images: (a) Fundus picture of the right eye showing the optic disc which is reddish in color, cup-disc ratio is obliterated but margins are sharp and vessels are normal, suggestive of mild disc edema. (b) Fundus picture of left eye showing the optic disc which is elevated and reddish in color, cup-disc ratio is obliterated and margins are blurred, indicating optic disc edema. Vessels are tortuous and dilated

case_images: The right eye optic disc was hyperemic with obscuration of the cup, but margins were sharp and vessels were normal, suggestive of mild disc edema [Figure 1a]. Vessels were tortuous and dilated [Figure 1b].
case_images: (a) VEP at presentation showing prolonged P-100 latencies in both the eyes. (b) Contrast enhanced MRI of brain WNL and orbits showing optic disc swelling in left eye. (c) Fundus fluorescein angiography of left eye showing leakage of dye from the optic disc in the late phase. (d) VEP at 1-month follow-up showing improvement in the P-100 latencies in both the eyes. VEP: Visual evoked potential, MRI: Magnetic resonance imaging, WNL: Within normal limit

case_images: Visual evoked potential (VEP) showed prolonged P-100 latencies from both the sides: 181.8 ms in the right eye and 178.5 ms in the left eye [Figure 2a]. In fundus fluorescein angiography, the right eye was WNL, whereas the left eye showed leakage of dye from the optic disc in the late phase [Figure 2c]. Contrast-enhanced magnetic resonance imaging brain and spine were WNL, but orbits showed optic disc swelling in the left eye [Figure 2b]. VEP latency improved in both the eyes to 105.0 ms in the right eye and 106.2 ms in the left eye [Figure 2d].
case_images: (a) HFA 30-2 of both the eyes at presentation, showing enlarged blind spot in the left eye and depressed peripheral fields in both the eyes. (b) HFA 30-2 at 1-month follow-up showing improvement of visual field defects in both the eyes, left improving more than the right. HFA: Humphrey visual field analysis

case_images: Humphrey visual field analysis (HFA 30-2) revealed enlarged blind spot in the left eye and depressed peripheral fields in both the eyes [Figure 3a]. The visual field defects in HFA 30-2 improved in both the eyes, left improving more than the right [Figure 3b].
