Impaired occipital lobe

Occipital lobe damage is a symptom manifested by occipital lobe tumors, occipital lobe cerebral infarction, and other diseases. The patient's occipital lobe was damaged. Mainly manifested as visual obstacles. In unilateral occipital lobe lesions, the central visual field often stays, which is the so-called macular avoidance phenomenon. Even if the bilateral occipital lobe is damaged, total blindness rarely occurs, and the central field of vision is always maintained. Acute damage to one side of the occipital lobe can cause transient total blindness. After a few hours, the visual field of the healthy side recovers, and the remaining lesion is isotropically blind. Clinically, the bilateral occipital lobe and thalamic fibrous lesions are completely blind, but the patient does not feel blind, which is called Anton syndrome.
