case_images: OCT-ONH performed on the patient's first visit. Scans show swelling of the right optic nerve head according to increased RNFL thickness.. OCT-ONH = optical coherence tomography-optic nerve head; RNFL = retinal nerve fiber layer

case_images: Fundus examination, however, showed localized swelling of the optic nerve head in the right eye, which was confirmed with optical coherence tomography (OCT) imaging (Figure 1).
case_images: A central 24-2 threshold visual field analysis of the right eye (left image) and left eye (right image) performed on the patient's first visit showing right visual field loss inferotemporally.

case_images: A central 24-2 visual field test showed a visual field loss inferotemporally (Figure 2).
case_images: OCT-ONH performed on the patient's second visit (19 days after the first visit) post intravenous steroid therapy showing improved RNFL thickness in the right eye.. OCT-ONH = optical coherence tomography-optic nerve head; RNFL = retinal nerve fiber layer

case_images: Nineteen days after the neurology consult, repeat OCT and visual field tests showed a slight improvement in retinal nerve fiber layer thickness (Figures 3, 4).
case_images: A central 24-2 threshold visual field analysis of the right eye (left image) and left eye (right image) performed on the patient's second visit (19 days after the first visit) post intravenous steroid therapy. Field analysis shows reduced peripheral vision loss inferotemporally.

case_images: Nineteen days after the neurology consult, repeat OCT and visual field tests showed a slight improvement in retinal nerve fiber layer thickness (Figures 3, 4).
case_images: OCT-ONH performed on the patient's third visit (40 days after the last steroid infusion). OCT shows superior optic nerve atrophy in the right eye based on reduced RNFL.. OCT-ONH = optical coherence tomography-optic nerve head; RNFL = retinal nerve fiber layer

case_images: A 40-day follow-up after intravenous methylprednisolone showed superior optic nerve atrophy in the right eye (Figure 5).
case_images: A central 24-2 threshold visual field analysis of the right eye (left image) and left eye (right image) performed on the patient's third visit (40 days after the last steroid infusion). Field analysis shows a reduction in peripheral vision loss inferotemporally.

case_images: The patient seemed to have sustained a permanent visual field deficit (Figure 6) likely from a COVID-19 hypercoagulable state.
