Videopupillographic and VER investigations in patients with congenital and acquired lesions of the optic radiation.

In 9 patients with congenital and acquired lesions of the optic radiation, videopupillographic investigations have been employed to determine the pupillographic threshold in the homonymous field defect. The study includes 3 patients suffering from congenital porencephalic cysts. The pupillary response was graded as akinetic, hypokinetic or eukinetic. These classifications yield some diagnostic clues as to the nature of the lesion. An attempt was made using the VER response in these patients to correlate the findings.
