Introduction: The purpose of this paper is to show a method of data fusion from two different tests: the multifocal visual evoked potentials (mfVEP) and humphrey visual field (HVF). Fusing the results may lead to a better diagnosis of various diseases associated with changes of patient's field-of-view.
Material And Methods: Two methods were used: mfVEP and HVF. MatLab environment was used for computer fusion of the images obtained in the mfVEP and HVF tests.
Result: The two methods results' fusion was achieved during computer experiments.
Conclusions: Achieved results will allow more precise and objective analysis of patient's field-of-view.

Purpose: We evaluated the performance of low contrast achromatic (LLA) multifocal visual evoked potentials (mfVEP) in preperimetric glaucoma and compared its diagnostic performance to other early diagnostic tests. We identified the clinically most useful tests and combinations in preperimetric glaucoma.
Methods: We studied 59 patients with at least one glaucomatous disc, with normal, reliable visual fields in that eye, and 17 normal controls.

Purpose: To evaluate longitudinal changes of visual function in relapsing-remitting multiple sclerosis (RRMS).
Methods: Multifocal visual evoked potential (mfVEP), contrast sensitivity (CS), and Humphrey visual fields (HVFs) were obtained at two visits (mean follow-up, 1.5 [±0.

Purpose: In previous studies, we applied receiver operating characteristic curve analysis to the signal-to-noise ratio distributions in the signal and noise windows of multifocal VEP (mfVEP) response. The areas under the curve thus obtained (SNR-AUC) were found to quantitatively detect glaucomatous visual field damage. The present study evaluated the reproducibility of SNR-AUC and the Humphrey visual field (HVF) global indices in 37 eyes with primary open angle glaucoma (POAG; POAG group) and in 30 controls (control group) within a 2-year period.

Background: There have been no studies investigating the correlation between structural [thickness of the retinal nerve fiber layer (RNFL) as determined by optical coherence tomography (OCT)] and functional [Humphrey visual field (HVF) or visual evoked potential (VEP) amplitude] measures of optic nerve integrity in patients with pituitary adenomas (PA).
Methods: Patients with PAs were recruited between September 2010 and September 2013. OCT, standard automated perimetry (SAP), and multifical VEP (mfVEP) were performed.

Background: We have previously reported that the degree of signal-to-noise ratio (SNR) distribution overlaps between a signal window and a noise window in multifocal VEP (mfVEP) responses, which is determined by the area under the receiver-operating characteristic curve termed SNR-AUC, can quantitatively detect glaucomatous visual functional damage. However, the effect of high myopia on this parameter is not yet known.
Methods: SNR-AUC, total deviation, and retinal sensitivity on the Humphrey visual field (HVF) test were compared among 34 eyes>-6 diopters (control) and 21 eyes≤-6 diopters (high myopia), both of which were ophthalmoscopically normal and had a best-corrected visual acuity of 20/20.
