The effect of stimulation of discrete areas of the retina on visual evoked potentials (VEP) was studied in 16 normal volunteers. The stimulus consisted of a constant luminance 2 degrees 18' field containing checks of 34'30' reversing at a frequency of 500 msec. The amplitude of the VEP was highest at the fixation point and inside the 2 degrees isopter.(More)
Confrontation field examination, perimetry, visual evoked potentials (VEPs) to pattern hemi-field stimulation and visual evoked spectrum array to flash stimulation were compared in 50 patients with homonymous hemianopsia. Visual field could be examined by confrontation in all patients and demonstrated the field defect in 96% of cases. Goldmann perimetry(More)
We conducted a study to compare the efficacy in migraine headache of nasal sumatriptan and intravenous ketorolac. The study was a prospective, double-blind study done with a convenience sample of 29 patients presenting to the emergency department (ED) with acute migraine. Patients received either 20 mg of nasal sumatriptan or 30 mg of intravenous ketorolac.(More)
