LED phonics stimulator for electroretinography: problems in the application of, and solutions

Development element base encourages the development and improvement of facilities for active biomedical research (eg, electroretinography). The emergence and widespread LED leads to the problem of adequate application of LED photonic stimulator in electroretinography. According to the standards ISCEV, used for electroretinography photostimulator based HID xenon lamps. When using LEDs in electroretinography as sources of light stimulus is necessary harmonization of the stimulus from the standard ( ) with the parameters of LEDs (lumens, lux). A comparison and mutual translation parameter photostimulator based on gas discharge lamps and LEDs.
