The value of visual evoked potentials in the evaluation of periorbital hemangiomas. [Case Reports, Journal Article]
Am J Ophthalmol 2005 Aug; 140(2):314-6.
PURPOSE: To present a case of a child with an extensive facial hemangioma in whom the suspicion of intracranial involvement was raised by visual evoked potential (VEP) evaluation.
DESIGN: Observational case report.
METHODS: VEP analysis was performed using flash and pattern stimuli to determine whether treatment intervention other than occlusion therapy was needed.
RESULTS: VEP analysis indicated a marked transoccipital asymmetry in the flash and pattern VEP suggestive of right hemispheric dysfunction. Neuroimaging showed intracranial extension of the hemangioma.
CONCLUSION: The VEP evaluation is a noninvasive technique performed in the awake child. This case highlights the usefulness of VEP analysis in the management of extensive periocular capillary hemangiomas and its use as a modality to identify potential intracranial involvement. Large plaquelike facial capillary hemangiomas may have possible underlying dural involvement suggestive of PHACES syndrome.
