[A PC program for evaluating electrophysiologic signals of mammalian eyes].
BACKGROUND
Electrophysiological measurements in the mammalian eye in vivo or in vitro, i.e. in the arterially perfused cat eye, require storage and analysis of a large amount of data: light-evoked signals, including the electroretinogram (ERG) and the optic nerve response (ONR) are stimulus-related and have to be measured in a triggered mode, whereas the DC-standing potential and flow rate of perfusion medium should be measured continuously.


RESULTS
In order to facilitate the analysis of these various signals, we developed a computer program, that allows an on-line data analysis and a trend indication for pharmacologically induced changes in signal size as well as efficient storage. The flexible system is based on a "labview" program, the application and efficiency of which are discussed.
