Surgical resection and laser thermoablation have been used to treat medically refractory epilepsy with good results. However, they are not without risk. One of the most commonly reported complications of temporal lobe surgery is contralateral superior homonymous quadrantanopsia. We describe a patient with quadrantanopsia discovered as part of our recently modified protocol to workup patients prior to epilepsy surgery. This field cut was subtle and not detected on routine neurological examination. While we understand that this is a single case, we advocate for more judicious preoperative visual field examinations to truly characterize the incidence of postoperative visual field lesions.
