Summary

The aim of this study is to measure visual acuity, contrast sensitivity and visual field by SAP-method using a novel device Ocusweep compared to currently widely used methods. Addition to that, the aim is to validate a novel perimetry method (Visual Search Test, VST) which is based on reaction times in visual decision- making task, where the subject is allowed to move eyes and where the fixation is verified by the subject himself in contrast to standard automatic perimetry (SAP) where prolonged stationary fixation and external fixation monitoring apparatus is required. Reaction-time based visual field device Ocusweep is compared to generally used SAP methods. Those tests will be done for healthy volunteers and for persons with diagnosed eye or brain disease.

Ocusweep OcuRT vision based choice reaction time test is validated for test repeatability and compared to Trail Making Test (TMT), Useful Field of View (UFOV) and Vienna Test System (VTS) reaction time tests. To evaluate the ability to detect unreliable results, OcuRT test is also done under cognitive load and with instructions to cheat the test.
