Homonymous visual-field defects result from insult to the retrochiasmal visual pathway, with 17 - 30 following acute stroke. Any recovery of a complete homonymous hemianopia typically occurs within the first 10 days after the ischemic event and improvement after 10-12 weeks is negligible. Only 38 - 48 of patients demonstrate any measurable improvement. No proven treatment exists for recovery of the impacted visual field. This is a report of a 69 year old male hospitalized for 8 weeks with septic shock. He was discharged as a quadruple amputee due to necrotizing fasciitis and pressor-induced ischemia. On the day of admission the patient experienced cardiac arrest for approximately 15 minutes and was subsequently noted to have large areas of ischemic change in the occipital and parietal lobes bilaterally. Following discharge a complete left homonymous hemianopia was noted and approximately 5 months after initial insult hyperbaric oxygen treatments were initiated.
