Arm Description
Comparable generally used method for measuring visual acuity, contrast sensitivity and visual field.
Outcomes
Primary Outcome Measures
Visual acuity
Visual acuity is measured as logMAR unit at the one visit for each patient using a novel reaction-time based visual field device and comparable method.
Secondary Outcome Measures
Contrast sensitivity
Contrast sensitivity is measured as logCS unit at the one visit for each patient using a novel reaction-time based visual field device and comparable method.
Reaction time visual field
Reaction time is measured using a novel reaction-time based visual field device and compared with generally used visual field program.
Vision based choice reaction time
Reaction time is measured with Ocusweep OcuRT test three times to asses repeatability of the test. OcuRT reaction time results will be 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 will also be done under cognitive load and with instructions to cheat the test.

5. Study Description
Brief 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.
