Espion Multifocal System

The Espion multifocal ERG system software and hardware has been developed by Diagnosys LLC to provide an easy to use clinical system for combined spatial and temporal information on retinal function. The default 61 element (max 243 element) is available with both short and long M-sequences. The full M-sequence test takes 8 minutes to perform with variable configurable segment lengths.
