In accordance with one aspect of the present invention, an optical coherence tomography instrument comprises an eyepiece for receiving at least one eye of a user is provided; a light source that outputs light that is directed through the eyepiece into the user's eye; an interferometer configured to produce optical interference using light reflected from the user's eye; an optical detector disposed so as to detect said optical interference; and electronics coupled to the detector. The electronics can be configured to perform a risk assessment analysis based on optical coherence tomography measurements obtained using the interferometer. An output device can be electrically coupled to the electronics, and may be configured to output the risk assessment to the user through the output device. The optical coherence tomography instrument can be self-administered, and the eyepiece can be a monocular system or a binocular system.

In accordance with one aspect of the present invention, an optical coherence tomography-based ophthalmic testing center system includes an optical coherence tomography instrument comprising an eyepiece for receiving at least one eye of a user or subject; a light source that outputs light that is directed through the eyepiece into the user's or subject's eye, an interferometer configured to produce optical interference using light reflected from the user's/subject's eye, an optical detector disposed so as to detect said optical interference; and a processing unit coupled to the detector. The ophthalmic testing center system can be configured to perform a multitude of self-administered functional and/or structural ophthalmic tests and output the test data

A system for detecting abnormal eye movement in a subject to indicate possible impairment of the subject. The subject may be presented with a visual pattern to observe. The visual pattern may cause the subject's eyes to move. Images of the eye movements may be captured. An eye motion pattern may be computed from the images. The eye motion pattern may be classified relative to other eye motion patterns or a guide. The classification may indicate whether there appears to be an abnormal movement of the eye and thus an impairment of the subject. An identification of the subject may be obtained according to a biometric from the images and used to retrieve the subject's baseline eye motion pattern. A comparison of the computed eye motion pattern and the baseline eye motion pattern may indicate whether there is abnormal movement of the eye and thus an impairment of the subject.
