Case Report

Left-sided metamorphopsia of the face and simple objects caused by an infarction at the right side of the splenium of the corpus callosum

A 78-year-old woman noticed that people's eyes and the right nasal foramens located in her left visual field looked smaller than those observed in the right. The woman reported no change in shape regarding facial outlines or scenic objects. Magnetic resonance imaging revealed an acute infarction of the right side of the splenium of the corpus callosum. Close examination revealed that her metamorphopsia affected the left side of her visual field, especially influencing facial components, particularly the eye. The woman had similar reactions to photographs of several kinds of animals, realistic portraits of humans, and caricatured humans. Meanwhile, presentings caricature human face at a 90° rotation elicited metamorphopsia in eyebrows located on the left side of a picture, but not the eyes. She also reported a change of shape or color tone for geometric objects. The patient's only symptom was metamorphopsia, and she did not show any other neurological defects such as callosal disconnection syndrome. Furthermore, objects that were affected by the patient's metamorphopsia (e.g. facial component especially the eye, and simple geometric figures) may be easy images to use in order to detect this type of distorted vision.
