A Case of Acquired Cerebral Achromatopsia Secondary to Posterior Cerebral Artery Stroke.

Impairment of color vision is known as "Achromatopsia." This condition is multifactorial with a myriad of causes, from local at the retinal level to central at the occipital cortex level. The most common causes are inherited conditions. However, acquired achromatopsia has been acknowledged in numerous case reports and studies. Achromatopsia secondary to posterior cerebral artery (PCA) stroke is an extremely rare phenomenon and had been reported in a few case reports. In this case, we report a patient presenting with achromatopsia as the only complaint due to an infarction of the left occipital cortex.
