Noninvasive Testing of Intrinsic Photosensitive Retinal Ganglion Cells. Development of a Mobile Video Memory Unit for applications of Chromatic Pupillometry

      Аннотация: In 1991 a special type of Retinal Ganglion Cells was unmasked as a “new" kind of photoreceptor that contributes to the circadian photo-entrainment and the pupillary light reflex. Very recent findings about the mechanisms and importance of these intrinsic photosensitive Retinal Ganglion Cells (ipRGCs) brought up the chromatic pupillometry, which enables to rate the ipRGC-activity. This elaboration proposes and describes a new compact and mobile device with an integrated video recording and memory unit that should simplify the application of the chromatic pupillometry or the testing of the ipRGCs and in the course of this enable the conducting of field studies. This elaboration is an ideal basis for further developments of mobile devices for chromatic pupillometry, especially with the aim of serial production.
