Abstract: This invention relates to testing and determining a threshold value used in psychometric testing in field of ophthalmology, neuro-ophthalmology and visual neuropsychology. The method comprises at least the following steps: a) displaying a symbol with a distinctive visual appearance and with a stimulus level to a display at a stimulus time-point, the symbol selected from a group of possible symbols, b) monitoring if a response is given on a response device with multiple choices, each choice representing a possible visual appearance or location of the symbol, and b1) if a response is not given in a response time-limit from the stimulus time-point, increasing the stimulus level of the symbol by a predetermined step and returning to step a), or b2) if a response is given in the response time-limit from the stimulus time-point, comparing the response to symbol displayed in step a), and c1) if the response does not correspond to the symbol displayed in step a), producing, e.g.

Abstract: This invention relates to a method for providing markers for evaluating and/or practising the visual field recognizable by an eye, and/or eyes, and/or visual system of a person. The method relies on the reporting of the person of identifications of fixation objects only identifiable when the eye or eyes of the person are accurately fixated on the fixation object. Accordingly active monitoring of a saccade, if a saccade triggering stimulus is employed; or smooth pursuit, if smooth pursuit triggering stimulus is employed, of the eye of the person is not needed for determining whereto to eye or eyes are fixated. The present invention also relates to the use of a system employing the method of the invention. The present invention further relates to a system for the method of the invention and a software product for the system.
