[Electrophysiology and early glaucoma diagnosis].

Glaucoma can lead to irreversible visual impairment. The pathogenesis of glaucoma is complicated and it is difficult to diagnose early. As an objective and functional examination tool, visual electrophysiology has its own advantages to detect early glaucomatous damage. It can indicate early functional degeneration of retinal ganglion cells and can direct doctors to diagnose and give treatment to glaucoma patients. It has been proved that the pattern electroretinogram, photopic negative response and multifocal electroretinogram can provide most of the information in the early diagnosis of glaucoma. This article overviews the latest application progress of these three visual electrophysiological techniques.-.
