During hospitalisation, he reported bilateral acute vision loss. His best-corrected visual acuity (BCVA) was counting fingers in the right eye and 20/200 in the left eye. Ocular fundus examination and optical coherence tomography revealed a slight alteration in the retinal nerve fibres in the nasal macular region. Automated perimetry revealed bilateral visual field defects affecting both temporal and nasal hemifields in a predominantly nasal distribution, and brain MRI confirmed symmetrical lesions within both lateral geniculate nuclei. BCVA was gradually recovered, reaching 20/20 within 6 weeks.
