For some individuals and for some locations, multifocal visual evoked potentials (mfVEP) may be too small or appear `too noisy' to be reliably measured. By adding electrodes, especially electrodes placed lateral to the midline, and by recording with multiple channels, the amplitude of the signal can be increased in some field locations. However, the(More)
OBJECTIVE To determine the relationship between spatially localized multifocal visual evoked potentials (mfVEPs) and Humphrey visual fields (HVFs) in patients with unilateral field defects. METHODS Humphrey visual fields and mfVEPs were obtained from 20 patients with unilateral field losses due to either ischemic optic neuropathy or glaucoma. Monocular(More)
Sixty local VEP records, called the multifocal VEP (mfVEP), can be obtained over a wide retinal area. From subject-to-subject, from day-to-day, and from location-to-location, these records can vary in quality presenting a challenge to quantitative analyses. Here three procedures are described for specifying the quality of mfVEP recordings in terms of(More)
BACKGROUND Although the use of endoscopes and image guidance provide some safeguards, motility complications from orbital injury during endoscopic sinus surgery still pose a significant concern and can provide a therapeutic challenge. METHODS We present the case of a 40-year-old woman with strabismus secondary to an iatrogenic injury to the medial rectus(More)
BACKGROUND Giant cell arteritis (GCA) is a common systemic vasculitis, with a presumed Caucasian predominance. The occurrence of GCA in Asians has rarely been addressed. This study aims to assess the incidence of giant cell arteritis in Asians. METHODS In this retrospective review, the self-reported ethnicities of patients with biopsy-proven GCA at the(More)
PURPOSE To report 3 cases of pleomorphic adenoma of the lacrimal gland with atypical features. METHODS The medical records, radiographic imaging, operative reports, and tumor histopathology of 3 patients with unusual presentations of pleomorphic adenoma of the lacrimal gland were reviewed. RESULTS All 3 patients were females ranging in age from 18 to 64(More)
PURPOSE We compared Humphrey Matrix FDT 30-2 (FDT) and Humphrey Visual Field Analyzer 30-2 SITA standard (SAP) in the assessment of anterior (optic nerve or chiasm) and posterior (retro-chiasmal) afferent visual pathway defects. MATERIALS AND METHODS In this retrospective comparative study, the charts of 37 patients (16 males, range 13-84 years, mean(More)
