[Progress of ophthalmic electrophysiology in China in past 5 years].

The main mission of visual physiology is to elucidate the neuromechanism of vision. The basic characters in visual process are the electrochemical changes of cell membrane and the active potential which transmits along neuraxon. This visual bioelectricity changes can be recorded by using visual stimulus, surface electrode and amplified recording apparatus. Clinical electrophysiology examination of vision has been an important clinical examination technique in ophthalmology. This technique provides a non-traumatic, objective, quantitative and location-detecting visual function examination procedure that can inspect visual path from the retina to visual cortex. Recently, visual physiology has gained noticeable development in basic research and clinical application. This article summarizes the development in this field.
