Abstract Purpose:To report a case of cortical blindness in a patient with cancer without severe higher cerebral dysfunction.

Case:A 67-year-old male underwent laparoscopic colon resection for transverse colon cancer. One month post-surgery, the patient's family noted the onset of visual impairment. On examination, the patient's visual acuity was 0.08 and 0.1 on the right and left respectively. Intraocular pressure was 19 and 16 mmHg on the right and left respectively. No abnormalities were identified in the anterior segment or fundus of the eyes. The visual field showed nonspecific defects in the inferior regions of both eyes. No higher functional impairment such as aphasia, apraxia, or speech apraxia. Computed tomography(CT)of the head showed hypo-absorption areas in the both occipital lobes. Magnetic resonance imaging(MRI)of the head(diffusion-weighted imaging)demonstrated acute cerebral infarction in the bilateral occipital lobes, leading to a diagnosis of cortical blindness. Anton's sign was positive due to the patient's ignorance of blindness by their patient. The cerebral infarctions were a cause of cortical blindness. After medical treatment, his visual field defects improved slightly, but his visual disturbances have not improved since.

Conclusion:Cortical blindness rarely occurs without an apparent higher cerebral dysfunction. We recommended performing a diffusion-weighted MRI of the head in patients with nonspecific visual field defects or visual impairment.
