Electroretinography Online Journals
Electroretinography (ERG) is an eye fixed test wont to measure the electrical potentials generated by light sensitive
cells of the attention , the rods and cones and their connecting ganglion
cells to detect function of retina. In ERG, an electrode is placed on the cornea at front of the attention to watch changes within the electrical potential of the attention in response to specific stimuli. Careful manipulation allows the clinician to research different cell types and layers of the retina. the danger is that cornea may get a short lived scratch on the surface from the electrode and perform again only after 1 hour. it's useful within the evaluation of hereditary and purchased disorders of the
retina and also useful in determining if retinal
surgery or the other ocular
surgery like cataract extraction is required. The instrument wont to conduct ERG is an electroretinograph and therefore the resultant recording is named an electroretinogram. Several sorts of ERG tests provide specific
information about the patient visual function, like photopic negative response and pattern ERG are useful in assessing retinal ganglion cell function in diseases like glaucoma. The multifocal ERG is employed to record separate responses for various retinal locations cross correlation techniques and ready to provide objective assessment of the central retinal function at different retinal areas within a brief duration of your time . the complete field ERG is that the commonest sort of ERG provides an assessment of general retinal function and may distinguish between the varied cell types, revealing the function of photoreceptors, bipolar cells, ganglion
cells and amacrine cells.
