Persisting flickering, c-shaped defect of the visual field in both eyes

A 26 y/o multigravida female described a persisting, flickering, c-shaped defect of the visual field in both eyes. The patient reported that her vision was impaired immediately after an emergency cesarean section. During onset of spinal anesthesia, the patient developed bradycardia and hypotension treated with intravenous ephedrine (10 mg) and inadvertently epinephrine (1 mg) instead of atropine. BP >300/200 mm Hg, cardiac arrhythmia and angina developed. After immediate induction of general anesthesia, she gave birth to a healthy boy. The patient recalled that her vision was impaired immediately after surgery. She described a flickering, c-shaped defect of the visual field in both eyes. How will you identify this vision defect?
