pas-de-deux: a term, originating in French, for a balletic performance with two dancers, often moving in unison
Amblyopia includes a number of conditions in which the single affected eye provides less useful information to the brain, resulting in suppression of that information in comparison to that from the more normal eye. Double vision or strabismus (crossed-eyes) from weakened eye muscles on the one side is a common cause. When strabismus is relatively minor, the persistence of two discordant images under certain conditions with resulting double vision, may be disconcerting to the adult patient. Reduced lighting, head position and fatigue may enhance the problem, but corrective prismatic lenses may help in reachieving integrated binocular vision.
