A congenital or acquired disorder marked by a monocular elevation deficiency. The patient is unable to raise one eye in all positions of gaze, usually resulting in hypotropia, i.e., one eye that is pointed downward relative to the other. It is often caused by inferior rectus muscle restriction. Other related ocular signs include abnormal head position, ptosis/pseudoptosis and vertical deviation in primary gaze.
