- Abstract
- Visual evoked potentials (VEP's) were studied in 19 children with surgically verified sellar or parasellar masses (7 craniopharyngioma, 3 optic chiasmal glioma, 3 granuloma, 1 hematoma, 1 arachnoid cyst, 1 medulloblastoma, 1 pituitary adenoma, 1 Rathke's cleft cyst and 1 germ cell tumor).
Abnormalities consistent with visual pathway dysfunction were recorded in 17 patients (89%). Absent responses or poor wave formations were noted in 7 patients and delayed P1 latency in 10 patients. Two patients, one with intrasellar Langerhans' cell granuloma and the other with pituitary adenoma, had normal evoked potentials.
The incidence and the degree of abnormalities in VEP's roughly correlated with the visual acuity. Postoperative VEP's were recorded in 5 patients and showed improvement in 4 patients. VEP's might be helpful for postoperative follow-up in children with sellar or parasellar masses.
