SYNOPSIS

Variable Frequency Photo-stimulation (VFP) goggles are a form of portable stroboscope, using red Light Emitting Diodes to alternately illuminate the right and left eyes, with the eyelids closed, at a rate of 0.5 to 50Hz. VFP goggles were used in the treatment of 7 patients with migraine headache. Of 50 migraine headaches recorded, 49 were rated by the patient as being helped and 36 as being stopped by using the VFP goggles. Treatment reduced the median duration of headache in all patients. The interval between migraine headaches appeared to be increased in the two cases with a follow up of more than 18 months. We conclude in this preliminary study that VFP appears to be effective in the treatment of migraine.
