Cerebral Embolism with Prosopagnosia and Cerebral Achromatopsia
A 57-year-old male presented with complaints of blurred vision OU for 1 week. He had received coronary artery bypass surgery 3 months ago and did not have any postoperative complications. His best-corrected visual acuity was 6/10 in both eyes. Intraocular pressures were normal. He could identify six plates in the right eye and seven plates in the left eye using the Ishihara test. Slit lamp examination showed normal anterior segments. Pupils were symmetric and reactive to light. Ophthalmoscopic examination revealed normal fundi in both eyes. Superior visual field defects were noted bilaterally (Fig. 51.1). MRI showed multiple lesions over the bilateral temporo-occipital lobe and left occipital lobe (Fig. 51.2).
