Cortical blindness following ictal nystagmus
V. Ramani
Both ictal nystagmus and cortical blindness may occur transiently in acute
cerebral disorders and therefore escape clinical detection, particularly in
confused, agitated patients. The following case report describes a young
woman with chronic myelogenous leukemia who became progressively ill
following bone marrow transplantation. During the course of her illness,
acute ictal nystagmus developed from focal right occipital ischemia;
postictally she remained cortically blind with possible visual
hallucinations for 48 hours.
