Abstract:
The present invention relates to a device and to a method for the quantitative detection of disorders in the field of vision of an eye of a test subject, in particular in the case of eye diseases which are associated with macular edema, wherein a square grid is displayed on a display device whose grid lines which are perceived by the test subject as curved can be modified by the subject in such a way that the subject can view an orthogonal reticule again. Such lines perceived as curved can be modified by input signals which modify the boundary curves defined by the boundary functions in such a way that the originally displayed linear reticule is perceived again, wherein the geometric deviations caused by transformation of the regions of the square reticule perceived as curved from the originally present squares are determined quantitatively as the sum of the absolute values of the horizontal deviations and as the sum of the absolute values of the vertical deviations.

Claim (Index 26):
A device for the quantitative detection and/or monitoring of disorders in the field of vision of an eye of a subject comprising:\n a display device; at least one control device for the display device and at least one processor and at least one storage device, wherein the device projects to the display device a square reticule consisting of a plurality of parallel equidistant horizontal lines and a plurality of equidistant parallel vertical lines with defined spacing and an essentially centrally arranged focus point, wherein each individual line of the square reticule can be changed into a curve by at least one input signal which is suitable to transform the nonlinear square reticule perceived by the subject as curved due to the disorder in the field of vision into the original square reticule again, wherein the boundary lines of each field of the square reticule is defined by boundary functions, which in an initial state are each displayed as lines so that the individual fields are geometrically present as squares and are displayed as such by the display device, but are in part perceived as curved by subjects with disorders in the field of vision; and the boundary lines which are perceived as curved can be modified by a series of input signals which modify the boundary curves defined by the boundary functions\u2014and not only the intersection points of the vertical and horizontal lines in the reticule\u2014in such a way that the original linear reticule can be perceived, wherein the geometric deviations caused by transformation of the regions of the square reticule perceived as curved from the originally present squares are determined quantitatively as the sum of the horizontal deviations and as the sum of the absolute values of the vertical deviations.
