Cortical blindness and visual imagery
Neurology, 1995 Controversy exists concerning the neural basis underlying visual imagery. Some propose that visual images evoked from memory are mediated by primary visual cortices. Others argue that these primary visual areas perform computations on elementary visual features when constructing visual representations from retinal input but that they are not activated ...

Clinical Neurology and Neurosurgery, 1997
A 79-year-old woman with persistent cortical blindness caused by bilateral temporo-occipital infarctions was followed for 8 months. She had no light or visual motion perception. Our patient's visual imagery was intact, which was demonstrated when drawing elementary shapes; however, her drawing of objects was poor.

Cortical Blindness in Preeclampsia
International Journal of Gynecology & Obstetrics, 1980ABSTRACTA 15‐year‐old primigravida with severe preeclampsia at term developed blindness. Following delivery by cesarean section, her visual acuity returned promptly. Computerized tomography demonstrated bilateral cerebral lesions in the occipital cortex, which resolved partially by five days and completely by seven months after delivery.
