The bioelectric field of the pattern electroretinogram in the mouse. [PDF]
Invest Ophthalmol Vis Sci, 2012 To compare the bioelectric field associated with the pattern electroretinogram (PERG) with that of the flash electroretinogram (FERG) in the mouse.PERGs and FERGs were recorded from each eye in 32 C57BL/6J mice using corneal silver loops referenced to a subcutaneous needle on the back of the head.

The pattern electroretinogram [PDF]
Eye, 1988 Physiological experiments and the exploitation of clinical conditions have provided compelling evidence that retinal ganglion cells and other inner retinal structures generate the pattern ERG (PERG). As an increasing number of clinical reports have been published some contradictory findings have been reported.

Pattern electroretinogram in glaucoma [PDF]
Current Opinion in Ophthalmology, 2006 Several studies have shown that the pattern electroretinogram, a direct, objective method of measuring retinal ganglion cell function, is altered early in ocular hypertension and glaucoma. Renewed interest in the pattern electroretinogram for early detection of pre-perimetric glaucoma has been sparked by noninvasive and reproducible methods of ...

Electrophysiological findings of Bardet–Biedl syndrome: a case series
Journal of the Egyptian Ophthalmological Society, 2020 Background Bardet–Biedl syndrome (BBS) is a very rare autosomal recessive genetic disease with multiple manifestations including the ocular system. Aim This study presents different electrophysiological and clinical findings in three female patients with

The multifocal pattern electroretinogram in glaucoma [PDF]
Vision Research, 2004 The pattern ERG can be used to detect early glaucomatous change, because the response of cells in the inner retina from (typically) 20 degrees -40 degrees of area is reduced before perimetric abnormality is certain. The multifocal pattern electroretinogram (mfPERG) allows analysis of many local regions within this area.
