The Dark Adaptometry module uses the ColorDome™ or ColorFlash™ stimulator to perform a full or partial field dark adaptation to accurately measure retinal parameters such as cone sensitivity, rod sensitivity and the rod-cone break point. The dark adaptometry test may be run for single or dual eye measurements or a combination. Protocols include the Marmor Test as well as a wide array of options for research and clinical use. The test detects cone and rod threshold as well as rhodopsin regeneration rates in fields of view from 12° to full-field. The patient’s eyes are displayed during testing in the Espion™ software and the results of multiple tests can be displayed in a single analysis plot.  

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

The Diagnosys Stepwise Sweep VEP (ssVEP) module is an automated method to assess visual acuity objectively using visual evoked potential (VEP) techniques. The Diagnosys ssVEP module is based on methods developed and published by Bach, et al1,2 and runs on a wide range of Diagnosys systems.
