Abstract: An ophthalmic optical coherence tomography instrument, method, and computer-readable medium. The instrument includes a scanner defining an apparent point source for scanning sample light across a subject position and an objective having a posterior imaging configuration to project the apparent point source onto a pivot point between the objective and the subject position. The objective is settable between the posterior imaging configuration for scanning the sample light across a retina of an eye at the subject position and an anterior imaging configuration for scanning the sample light across a pivot plane. An axial region from which an interferogram is detectable extends across the pivot plane while the objective is in the anterior imaging configuration. A pupil alignment method uses the anterior imaging modality to obtain a structure position of a structure of an eye's anterior segment and then an offset between the structure position and a reference position.

Abstract: Face protection equipment that comprises an eye imaging module for measuring an eye component (such as a retina, sclera, cornea, iris, limbus, pupil, or eyelid), can be used to measure an ocular parameter (such as saccades, vergence, smooth pursuit, gaze, eye fixation, pupil size, or eyeblinks). This ocular parameter measurement can then be used to assess human health, such as a traumatic brain injury. It can also be used to develop and implement ocular training protocols on a user-viewable display, and to assess the effects of a pharmacologic intervention.
