DiagnosysFST Upgrade Module - Brochure

The DiagnosysFST®, Full-field Stimulus Threshold, module uses the ColorDome™or ColorFlash™ stimulator. It measures the sensitivity of the visual field by testingfor the lowest luminance flash which elicits a visual sensation perceived by thesubject. The test is run on either dark- or light-adapted patients for one or botheyes in an automated routine to measure a reliable threshold. During testing, the Espion™software, uses a proprietaryprobability density function toautomatically determine thethreshold. The test can be used as aprimary endpoint or as a safetyprocedure to detect increasesor decreases in light sensitivitydue to gene therapies ordeterioration or improvementin existing patient conditions
