چکیده
The anesthesiologist clearly caused this patient’s vision loss by letting the mean arterial blood pressure drop below 60 mmHg for more than 5 min. This patient is now blind because the anesthesiologist let the patient’s hematocrit level decrease to less than 24% during the case. The person providing the patient’s anesthesia failed to avoid prolonged pressure on the eye, leading to the patient’s ischemic optic neuropathy and blindness.
