Electroretinography Scholarly Journals

Electroretinography (ERG) is an eye test used to measure the electrical potentials generated by light sensitive cells of the eye, 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 eye to monitor changes in the electrical potential of the eye in response to specific stimuli. Careful manipulation allows the clinician to investigate different cell types and layers of the retina. The risk is that cornea may get a temporary scratch on the surface from the electrode and perform again only after 1 hour. It is useful in the evaluation of hereditary and acquired disorders of the retina and also useful in determining if retinal surgery or any other ocular surgery such as cataract extraction is required. The instrument used to conduct ERG is an electroretinograph and the resultant recording is called an electroretinogram. Several types of ERG tests provide specific information about the patient visual function, such as photopic negative response and pattern ERG are useful in assessing retinal ganglion cell function in diseases like glaucoma. The multifocal ERG is used to record separate responses for different retinal locations cross correlation techniques and able to provide objective assessment of the central retinal function at different retinal areas within a short duration of time. The full field ERG is the most common type of ERG provides an assessment of general retinal function and can distinguish between the various cell types, revealing the function of photoreceptors, bipolar cells, ganglion cells and amacrine cells. Scholarly journal is a peer-reviewed journal in which scholarship relating to a particular academic discipline is published. Scholarly journals serve as forums for the introduction and presentation for scrutiny of new research, and the critique of existing research. Content typically takes the form of articles presenting original research, review articles, and book reviews. The term Scholarly journal applies to scholarly publications in all fields; this article discusses the aspects common to all academic field journals.
