The invention relates to a method and a system for evaluating reliability of results in a visual reaction test taken by a user. Method steps with following phases are repeated several times: Correlation between step times and delay times or correlation between reaction times and delay times is compared with predefined correlation values for reliability and thereby the level of reliability of the results is determined.

Method and system for evaluating reliability of results in a visual reaction test

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:

Testing and determining a threshold value

The invention relates to a perimeter or a campimeter with a visible fixation point and a method used in them. The method comprises at least the following steps:

Automated perimeter

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.

Method for assessing function of the visual system and apparatus thereof

This invention relates to a method for providing markers for evaluating and/or practicing 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.
