Painful ophthalmoplegia due to idiopathic granulomatous inflammation of the cavernous sinus/superior orbital fissure has been termed Tolosa-Hunt syndrome (THS). This report is based upon 146 patients with this syndrome published in the English literature. The clinical profile, natural history, diagnostic evaluation, pathologic findings, differential(More)
PURPOSE This study was designed to examine the on-road driving performance of drivers with hemianopia and quadrantanopia compared with age-matched controls. METHODS Participants included persons with hemianopia or quadrantanopia and those with normal visual fields. Visual and cognitive function tests were administered, including confirmation of hemianopia(More)
PURPOSE To compare eye and head movements, lane keeping, and vehicle control of drivers with hemianopic and quadrantanopic field defects with controls, and to identify differences in these parameters between hemianopic and quadrantanopic drivers rated safe to drive by a clinical driving rehabilitation specialist compared with those rated as unsafe.

Visual loss due to optic nerve injury after closed head trauma constitutes a formidable diagnostic and therapeutic challenge for the clinician. Assessment must be made of the site of optic nerve injury, and this is often difficult in the patient with an altered level of consciousness. A decision regarding optic nerve decompression must be formulated, yet(More)
We examined 24 individuals in four family pedigrees with dominantly inherited optic atrophy (DOA); 12 patients met the criteria for diagnosis of DOA and two were suspect. Our data indicate that (1) insidious onset usually occurred in childhood, but subjective visual symptoms may evolve in adulthood; (2) visual function was minimally (20/25) to moderately(More)
OBJECTIVE To report a patient with agenesis of the right internal carotid artery associated with ipsilateral, congenital Homer's syndrome. DESIGN Case report. METHODS A 30-year-old woman, with a past history of migraine headaches, underwent neuro-ophthalmologic and neuroradiologic evaluation for transient visual obscurations and congenital Horner's(More)
A 49-year-old man requiring hemodialysis for end-stage renal disease developed orbital cellulitis and bilateral central retinal artery occlusions. Although cranial computed tomography demonstrated ethmoid and sphenoid sinusitis, two surgical biopsy specimens of sinus mucosa were nondiagnostic. Autopsy findings confirmed cerebral mucormycosis with bilateral(More)
Most documented cases of radiation-induced optic neuropathy are unilateral and occur more than 1 year after radiotherapy to the sellar region. We describe a patient with bilateral radiation optic neuropathy 3 months following the completion of radiotherapy. MRI 13 months after the onset of visual failure showed bilateral optic atrophy with residual(More)
OBJECTIVE To examine whether some drivers with hemianopia or quadrantanopia display safe driving skills on the road compared with drivers with normal visual fields. METHOD An occupational therapist evaluated 22 people with hemianopia, 8 with quadrantanopia, and 30 with normal vision for driving skills during naturalistic driving using six rating scales.(More)
