BACKGROUND Optic disc drusen (ODD) are hyaline deposits located within the optic nerve head. Peripapillary retinal nerve fiber layer (RNFL) thinning is associated with the high prevalence of visual field defects seen in ODD patients. The goal of this study was to investigate the characteristics of patients with ODD and to compare the peripapillary RNFL(More)
OBJECTIVE Cardiovascular complications including cardiac arrest and arrhythmias remain a clinical challenge in the management of acute traumatic spinal cord injury (SCI). Still, there is a lack of knowledge regarding the characteristics of arrhythmias in patients with acute traumatic SCI. The aim of this prospective observational study was to investigate(More)
BACKGROUND Autonomic function has received little attention in Alzheimer's disease (AD). AD pathology has an impact on brain regions which are important for central autonomic control, but it is unclear if AD is associated with disturbance of autonomic function. OBJECTIVE To investigate autonomic function using standardized techniques in patients with AD(More)
PURPOSE To explore the applicability of multifocal visual evoked potentials (mfVEPs) for research and clinical diagnosis in patients with optic disc drusen (ODD). This is the first assessment of mfVEP amplitude in patients with ODD. METHODS MfVEP amplitude and latency from 33 patients with ODD and 22 control subjects were examined. Mean amplitude, mean(More)
TO THE EDITOR: We read with interest the study by Traber et al, where the presence or absence of visual field defects was correlated with optic nerve head drusen (ONHD) morphology. The ONHD were classified using enhanced depth imaging optical coherence tomography (OCT) morphologic characteristics as either peripapillary, granular, or confluent. The(More)
Purpose Optic disc drusen (ODD) are found in up to 2.4% of the population and are known to cause visual field defects. The purpose of the current study was to investigate how quantitatively estimated volume and anatomic location of ODD influence optic nerve function. Methods Anatomic location, volume of ODD, and peripapillary retinal nerve fiber layer and(More)
A spinal cord injury (SCI) interferes with the autonomic nervous system (ANS). The effect on the cardiovascular system will depend on the extent of damage to the spinal/central component of ANS. The cardiac changes are caused by loss of supraspinal sympathetic control and relatively increased parasympathetic cardiac control. Decreases in sympathetic(More)
