Horner's Syndrome: Loss of sympathetic nervous system input to (in this case)left eye.

Note that left pupil is smaller than right. Also that left eyelid covers a greater portion of eye than on right
(known as ptosis). The etiology in this case was itiopathic, though it can be associated with tumors
occurring at the apex of the lung, among other things.
