Senescent Changes and Topography of the Dark-Adapted Multifocal Electroretinogram
Purpose To investigate the topographic changes of the dark-adapted multifocal electroretinogram (mfERG) across adulthood in the central retina and compare the topography between macular versus extramacular, nasal versus temporal, and inferior versus superior retinal areas. Methods Sixty-five subjects (18-88 years) received a comprehensive dilated eye examination to ensure the health of their ...
متن کاملStudy of blue and red flash in dark-adapted electroretinogram.
PURPOSE To investigate the characteristics of the waveform generated by blue and red light stimulations in a dark-adapted electroretinogram (ERG) and those of cone responses in the dark-adapted condition. METHODS The study subjects were 52 persons (88 eyes) with no previous medical history. The author recorded b-waves (rod response) with red light stimulation and the x-waves (dark-adapted con...
متن کاملChemogenetic Activation of ipRGCs Drives Changes in Dark-Adapted (Scotopic) Electroretinogram
Purpose The purpose of this study was to investigate the impact of activating melanopsin-expressing intrinsically photosensitive retinal ganglion cells (ipRGCs) on dark-adapted (scotopic) electroretinograms (ERG). Methods We used mice (Opn4Cre/+) expressing cre recombinase in melanopsin-expressing cells for a targeted gene delivery of a chemogenetic Gq-coupled receptor, hM3Dq, to ipRGCs. Intr...
متن کامل[Characteristics of dark-adapted and light-adapted oscillatory potentials in human electroretinogram].
OBJECTIVE To characterize dark-adapted and light-adapted oscillatory potentials (OPs) in human electroretinogram (EGR) elicited by flashing light stimulation of the same intensity. METHODS Dark- and light-adapted ERGs of normal eyes were studied. The frequency spectra of the extracted dark-adapted OPs and light-adapted OPs were analyzed by a fast Fourier transform. The peak frequency, latency...
متن کاملMultifocal 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 ...
