title: Transient cortical blindness after intradiscal oxygen-ozone therapy.
abstract: A 54-year-old caucasian male developed bilateral blindness during an oxygen-ozone injection for disc herniation. The visual loss (VL) was immediately followed by severe frontal headache, vomiting, and nausea. The patient underestimated the VL showing Anton's syndrome, with a complete visual recovery after 2-month follow-up. Magnetic resonance data were consistent with recent ischemic lesions in bilateral vascular territories of posterior cerebral arteries.
