English: A montage of five pictures of the right eye of a male subject with partial heterochromia, taken by tilting his head at angles 90°, 45°, 0°, -45°, and -90° of an upright position (where positive angles are understood as him leaning to his right-hand side). The subject has blue-green irises, and the partial heterochromia takes the form of a brown band from a point under the pupil to the bottom of the iris, allowing the torsional movement of the eye to be especially apparent.
