Acute Visual Field Defect following Vitrectomy Determined to Originate from Optic Nerve by Electrophysiological Tests

Case Reports in Ophthalmology, 2012
Purpose: To present our findings on the cause of an acute visual field defect (VFD) that developed in a patient on the day after vitrectomy for proliferative diabetic retinopathy.

The Effects of Alcohol on Visual Evoked Potential and Multifocal Electroretinography

Journal of Korean Medical Science, 2016
The aim of this study was to investigate the acute effects of ethanol administration on pattern-reversal visual evoked potential (VEP) and multifocal electroretinography (mfERG). Fifteen healthy subjects with no ocular or general disease were recruited. VEP (0.25° pattern sizes) and mfERG with 19 elements in two recording segments were performed before

Multifocal visual evoked potential for evaluation of open-angle glaucoma

Medical hypothesis discovery and innovation in ophthalmology, 2021
Background: To correlate multifocal visual evoked potential (mf VEP) findings with static automated perimetry (SAP) and spectral-domain optical coherence tomography (SD-OCT) in eyes with primary openangle glaucoma (POAG).Methods: This cross-sectional study included a consecutive sample of 40 eyes of 40 patients with POAG.

Case of Unilateral Peripheral Cone Dysfunction

Case Reports in Ophthalmology, 2012
Purpose: Peripheral cone dystrophy is a subgroup of cone dystrophy, and only 4 cases have been reported. We present a patient with unilateral peripheral cone dysfunction and report the functional changes determined by electrophysiological tests and ...

Application of multifocal visual evoked potentials in the assessment of visual dysfunction in macular diseases. [PDF]

Eye (Lond), 2011
To evaluate the use of AccuMap multifocal visual evoked potentials (mfVEP) in visual dysfunction caused by macular diseases.Forty-eight eyes with known macular diseases underwent AccuMap mfVEP and microperimetry 1 (MP1) assessments. Evaluation of mfVEP abnormality was based on an amplitude deviation probability plot and the AccuMap Severity Index (ASI).

The Effects of Retinal Abnormalities on the Multifocal Visual Evoked Potential

Investigative Opthalmology & Visual Science, 2006
To examine the effects on the amplitude and latency of the multifocal visual evoked potential (mfVEP) in retinal diseases associated with depressed multifocal electroretinograms (mfERG).Static automated perimetry (SAP), mfERGs, and mfVEPs were obtained from 15 individuals seen by neuro-ophthalmologists and diagnosed with retinal disease based on ...

Retinal Changes After Posterior Cerebral Artery Infarctions Display Different Patterns of the Nasal und Temporal Sector in a Case Series

Frontiers in Neurology, 2020
Background: Visual field defects are a common and disabling consequence of stroke and a negative prognostic factor of patient's quality of life. They result from lesions in different parts of the visual system, most commonly the visual cortex and optic ...

Long-Term Follow-Up of a Family with Retinal Dystrophy Caused by RPE65 Mutation

Case Reports in Ophthalmology, 2023
We present here the case histories of two siblings, a boy and a girl, with Leber’s congenital amaurosis (LCA). The diagnosis was based on non-recordable full-field electroretinogram (ffERG).

Multifocal visual-evoked potential in unilateral compressive optic neuropathy [PDF]

British Journal of Ophthalmology, 2006
To evaluate the effects of unilateral compressive optic neuropathy on amplitude and latency of multifocal visual evoked potentials (mfVEPs).Static automated perimetry and mfVEP recordings were obtained from six patients with presumed meningiomas affecting one optic nerve.
