MULTIFOCAL ELECTRORETINOGRAM IN BIRDSHOT CHORIORETINOPATHY

Retina, 2015
To characterize multifocal electroretinogram parameters in patients with birdshot chorioretinopathy.Twenty-eight patients with birdshot chorioretinopathy consecutively included from 2006 to 2011 were matched to 27 healthy subjects for age, axial length, and lens status.

Multifocal Electroretinograms in Normal Subjects

Japanese Journal of Ophthalmology, 1998
Multifocal electroretinography (ERG), developed by Sutter in 1992, is a method of recording the spatial distribution of focal ERG in a short time period using multi-input stimulation. Using this technique, we can detect the spatial extent and severity of damage to the macula. In this study, we recorded multifocal ERGs from 20 eyes of 20 normal subjects

Voluntary suppression of the multifocal electroretinogram

Ophthalmology, 2004
To describe multifocal electroretinogram (mfERG) responses in 2 patients with nonorganic visual loss and in 11 eyes of 6 healthy persons who suppressed their mfERG responses.Observational case series.The mfERG results were recorded in all individuals using the Veris Science 4.2 instrument.

The multifocal electroretinogram (mfERG) in the pig

Acta Ophthalmologica Scandinavica, 2007
Abstract.Purpose:  To establish a method allowing multifocal electroretinography (mfERG) recording with simultaneous fundus monitoring on anaesthetized pigs. In addition we characterize the peaks of the porcine mfERG trace, and compare the visual streak area with the optic nerve head, a known non‐response area.

The multifocal electroretinogram in retinal detachment

Documenta Ophthalmologica, 1997
We evaluated the retinal electrophysiologic function in both the detached and attached areas of eyes with retinal detachment, and assessed the functional recovery of these areas after surgery by quantifying the results obtained from multifocal electroretinograms.

The Effects of Aging on the Multifocal Electroretinogram

Japanese Journal of Ophthalmology, 2001
In order to use multifocal electroretinogram (m-ERG) for clinical assessment, we investigated the effects of aging on waves of the first and second order kernels of the m-ERG.m-ERGs were recorded from 93 eyes (refractive error 0-(-)3.0 D) of 56 normal subjects (range 12-79, mean 44.2 +/- 20.7 years of age) using the Visual Evoked Response Imaging ...

Multifocal Electroretinogram in Central Serous Chorioretinopathy

Japanese Journal of Ophthalmology, 2000
Purpose: An assessment of retinal function topographically in the affected eyes with central serous chorioretinopathy (CSC).Participants and Method: We recorded multifocal electroretimogram (mERG) in 5 patients with unilateral CSC, and analyzed the topographical properties in the central visual field (rings #1 + 2).Results: mERG amplitudes in the CSC ...

The multifocal electroretinogram in central serous chorioretinopathy

Ophthalmic and Physiological Optics, 2002
Purpose: To compare multifocal electroretinograms (ERGs) in control subjects and patients with central serous chorioretinopathy (CSC). Method: Eighteen eyes of control subjects and 15 eyes affected by CSC were tested with a VERIS ...

The effects of fundus photography on the multifocal electroretinogram

Documenta Ophthalmologica, 2016
To determine the effect of flash fundus photography (FFP) on the multifocal electroretinogram (mfERG).Ten subjects underwent mfERG testing on three separate dates. Subjects received either mfERG without FFP, mfERG at 5 and 15 min after FFP, or mfERG at 30 and 45 min after FFP on each date. The FFP groups received 10 fundus photographs followed by mfERG

Effects of refractive blur on the multifocal electroretinogram

Documenta Ophthalmologica, 1999
A significant difference in the response density of the MF-ERG response has been suggested for every 2 diopter change of refraction. The influence of refractive blur on the MF-ERG was studied in 8 healthy volunteers using either the VERISTM system (Group A: n=5) or Retiscan(TM) (Group B: n=3).
