Hemianopia: a presenting feature of acute epidural hematomas.
Visual field abnormalities were studied in a retrospective analysis of 199 patients with epidural hematomas. One hundred three patients had been alert enough at the time of hospital admission to have had their visual fields examined, but in only 27 patients were visual fields documented in the charts. Six of the 27 patients (22%) had a correctly localizing homonymous hemianopia. The case histories of these 6 patients are detailed and the pathogenetic mechanisms of the visual field abnormalities are discussed. The importance of recognizing that homonymous hemianopia can be an early sign of an epidural hematoma is stressed.
