Multifocal electroretinogram in myopia.
PURPOSE To investigate early changes of retinal function in myopic eyes, patients with various degrees of myopia underwent multifocal electroretinography (multifocal ERG). METHODS Thirty young patients (mean age, 26.1 years) were divided into three groups according to the degree of refractive error: emmetropia/low, medium, and high myopia. All groups were matched by sex and age. All subjects ...
متن کاملMultifocal electroretinogram in patients with central serous chorioretinopathy.
PURPOSE To assess local retinal function of macula in patients with central serous chorioretinopathy (CSC). METHODS Multifocal electroretinograms (ERGs) were recorded in 5 patients with unilateral CSC and 20 normal subjects. The waveforms from the central retina within 5 degrees of visual angle were analyzed. The first negative trough was designated as N1, the first positive peak as P1, and t...
متن کاملMultifocal electroretinogram abnormalities persist following resolution of central serous chorioretinopathy.
OBJECTIVE To examine results of the multifocal electroretinogram (MERG) after spontaneous resolution of central serous chorioretinopathy (CSC) detachments. METHODS Multifocal electroretinograms were recorded from both eyes of 5 recovered patients with CSC and 10 age-matched healthy subjects. All patients with CSC had bilaterally subnormal MERG amplitudes during a first attack of CSC occuring ...
متن کاملMultifocal electroretinogram in birdshot chorioretinopathy.
PURPOSE To characterize multifocal electroretinogram parameters in patients with birdshot chorioretinopathy. METHODS 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 electroretinogram was prospectively evaluated using the Vision Monitor system. RESULTS Birdsho...
متن کاملClinical evaluation of multifocal electroretinogram.
PURPOSE To compare the multifocal electroretinogram (ERG) system to conventional ganzfeld and focal ERGs obtained from patients with known retinal diseases to assess its clinical applicability. METHODS A multi-input system analysis was used to explore the field topography of ERG responses to local luminance modulation in patients with retinitis pigmentosa, pericentral pigmentary retinal dystr...
