1. An optical coherence tomography instrument comprising:
an eyepiece for receiving at least one eye of a user;
at least one target display visible through said eyepiece;
a light source that outputs light that is directed through the eyepiece to the at least one eye of the user;
an interferometer configured to produce optical interference using light reflected from the at least one eye of the user;
an optical detector disposed so as to detect said optical interference; and
electronics coupled to the at least one target display and said optical detector and configured to provide an output based on optical coherence tomography measurements obtained using said interferometer,
wherein said electronics are further configured to monitor a gaze of the user by tracking detectable structures of the at least one eye and conduct an extraocular motility test based on the gaze of the user, and
wherein said electronics are further configured to combine measurements from the extraocular motility test to deduce potential underlying cranial nerve palsies.
