A method for determining the torsional component of an eye around the viewing direction comprises the steps: Recording an image of the eye (110); Extracting at least one "region of interest" (120) and transformation into a polar coordinate image (130); Detecting objects of at least one predefined object type in the polar coordinate image (140); Generating a function of the respective object type depending on the polar coordinate angle Phi (150); Generating a code from the functions of the object types depending on the polar coordinate angle Phi (160); and comparing the code (30) with a code being determined from a previous recording (170). The function of each object type is a 1-dimensional function, which is generated by combining (e.g. summarizing) along the radial component. A device for determining a measure of the torsional position of the eye position is designed for performing the method. |
