Software Overview

The Espion software has been designed to help interrogate the visual system layer by layer to provide objective assessment of macular, pan-retinal and optic nerve function. It not only performs all the standard ISCEV clinical vision tests but is also capable of performing new tests as they are developed. Based around a fast PC running Windows and written in conjunction with leading experts in the field, it incorporates into its design many aspects that are very desirable for electrophysiology including a proper client/server SQL database, advanced normal selection, fully programmable protocols, digital filtering, automatic report generation and proper diagnosis facilities. The software supports multiple external stimulators with options for expansion as technology changes.
