  • latency
  • Dopamine precursor therapy differently reduced the VEP latency, depending on the spatial frequency of the visual stimulus. (bmj.com)
  • Monocular
  • 8 Anatomic studies of the effects of monocular visual deprivation on the sizes of cells in the lateral geniculate nucleus (LGN) of nonhuman primates have shown differential effects of visual deprivation on magno- and parvocellular cells, marked changes in LGN cells related to the fellow eye, and major differences in the effects of early- and late-onset monocular visual deprivation.

  • Healthy Eyes
  • To evaluate the ability of the short-duration transient visual evoked potential (SD-tVEP) to discriminate between healthy eyes and eyes with early to advanced glaucomatous visual field loss. (arvojournals.org)
  • Short-duration transient VEP objectively identified decreased visual function and discriminated between healthy and glaucomatous eyes, and also showed good differentiation between healthy eyes and those with early visual field loss. (arvojournals.org)
  • optic neuritis
  • Acute optic neuritis (ON) is often followed by recovery of visual function. (arvojournals.org)
  • Acute optic neuritis (ON) is often followed by recovery of visual function, 1 even if accompanied by significant optic nerve atrophy. (arvojournals.org)
  • When considering the MD and the PSD of the three techniques in the group of MS patients who had a history of optic neuritis, a significant correlation was found only between CAP MD and SWAP MD (r=0.0057), with a tendency by SWAP to reveal a higher rate of visual field loss.

  • improvements
  • Recent improvements to visual evoked potential (VEP) technology, such as reduced testing time, real-time electrode sensor status to measure of the quality of the interface between the electrodes and the patient's scalp, and temporally locked data collection to increase the signal-to-noise ratio by preventing contamination of the relevant VEP frequency component from other frequency components in the response, have led to its becoming a tool for clinical use. (arvojournals.org)
  • differences
  • Inside this group, the MD and the PSD of the three techniques were correlated (Spearman's rank test), in order to investigate whether any significant differences might be revealed by these techniques in pointing out the total amount of visual field damage. (eur-j-ophthalmol.com)
  • patients
  • 3 , 5 The resulting interpolated visual‐field plots were colour coded by comparing the deviation in each segment to a group of 100 control patients. (pubmedcentralcanada.ca)
  • Subjective visual vertical (SVV) judgment and standing stability were separately investigated among patients with adolescent idiopathic scoliosis (AIS). (frontiersin.org)
  • To examine changes in color- and motion-related visual function in patients with strabismic amblyopia. (arvojournals.org)
  • The results of this study demonstrate their efficacy also in detecting early visual field deficits in MS patients without clinical signs of optic neuropathy. (eur-j-ophthalmol.com)
  • This study pinpoints the analysis of VEP response as a potentially accurate and non-invasive approach to assess neural activity and visual information processing in NPC1 patients, as well as for monitoring the progression of the disease and assessing the efficacy of potential therapies. (biomedcentral.com)
  • pathways
  • This genuine optimised monitoring in France, set up in association with Metrovision company, should help increasing intraoperative VEP reliability as a monitoring tool for visual pathways function. (clinicaltrials.gov)
  • plots
  • Door een visuele stimulans te presenteren aan de patient zoals bijvoorbeeld een bewegende lijn (motion Visual Evoked Potentials (mVEP)) of een plots anderskleurig beeld (P300 "oddball") kunnen we met EEG een piek meten die een constant tijds patroon vertoond afhankelijk van het moment van stimulatie. (scriptiebank.be)
  • response
  • Based on these findings, we assume that the relationship between IAF and neuronal and vascular response stems from the size of the network recruited for visual processing. (ovid.com)
  • The relation between IAF, alpha-amplitude, evoked potential and vascular response is discussed in the framework of a simple heuristic model. (ovid.com)
  • study
  • Through event-related potentials (ERPs), the present study examined the effect of postural control demands (PDs) on AIS central mechanisms related to SVV judgment and standing stability to elucidate the time-serial stability control process. (frontiersin.org)
