Abnormal visual fixation Eccentric visual fixation 2017-07-09T12:48:35Z Eccentric fixation A anomaly in which a part of the retina other than the fovea is used for visual fixation. The fovea usually retains its straight ahead orientation. Eccentric fixation may be present under conditions of viewing with one or both eyes. However, it is more easily diagnosed monocularly (especially if the better eye is covered). A uniocular condition in which there is fixation of an object by a point other than the fovea. This point adopts the principal visual direction. The degree of the eccentric fixation is defined by its distance from the fovea in degrees.
