Introduction: Adaptation is one of the key characteristic of our vision which can maximize the visual function. It applies to both spatial and temporal characteristics. The fast flickering stimulation characteristics of the multifocal electroretinogr

Aim To examine the influence of cloudy media on the slow double-stimulation multifocal electroretinogram (mfERG). Methods Slow double-stimulation mfERG responses were measured from 26 subjects with normal ocular health under normal and light scatteri

Purpose This study investigated the retinal adaptive mechanism in inner retinal dysfunction using the slow double-stimulation multifocal electroretinogram (mfERG) paradigm. Methods Slow double-stimulation mfERG responses were recorded from 15 eyes of

We investigated characteristics of multifocal electroretinograms (mfERG) from in vitro perfused porcine eyes. TTX, NMDA, APB, and PDA were used to identify contributions to the mfERG from inner retinal neurons, ON-pathway, OFF-pathway, and photorecep

Multifocal ERG (mfERG) and multifocal VEP (mfVEP) have been used widely in the investigation of pathological changes or functional variations in the visual system. Altitudinal hemifield loss is a visual field defect that is usually found in patients

Using hydrazone chemistry, a simple dynamic system of macrocyclic pseudo-peptides was prepared which contains a cyclic structure that resembles a known receptor for ammonium cations. A series of ammonium salts were tested as templates and the expecte
