Abstract: Systems, devices, and methods are described for assessing the risk of developmental, cognitive, social, or mental abilities or disabilities in very young patients (e.g., in the first 2-6 months of life). Generally, the decline in visual fixation of a subject over time with respect to certain dynamic stimuli provides a marker of possible abilities or disabilities (such as ASD). The visual fixation of the subject is identified, monitored, and tracked over time through repeated eye tracking sessions, and data relating to the visual fixation is then analyzed to determine a possible increased risk certain conditions in the subject. A change in visual fixation as compared to similar visual fixation data of typically-developing subjects or to a subject's own, prior visual fixation data provides an indication of a developmental, cognitive, or mental ability or disability.

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.

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.
