One Episode of Cortical Blindness Following Myodil Myelography

Abstract

This presentation describes the visual and mental changes in one episode of transient cortical blindness following Myodil myelography.
Blindness was first detected from 6 hours after the myelography (absent light perception, but active papillary light responses). Even though unable to see, the patient seemed unconcerned about his blindness. There were numerous globules of Myodil scattered throughout the base of posterior fossa. By CT-scan, the infarction of left posterior lobe was suggested. Subsequently only quadrant hemianopia remains.
