However, further exam showed mild proptosis with Hertel exophthalmometric measures as: 20 OS, 24 OD, and restricted supraduction, adduction OD in extraocular eye movements.
The final neurological examination revealed mild supraduction and restriction of adduction OD as well as improved proptosis (Hertel exophthalmometric exam: 20 OS, 22 OD).
The term 'elevation' to describe an upward rotation and 'depression' for a downward rotation tend to be used in favour of the more logical supraduction and infraduction.
It is caused by conversion of lateral rectus muscle function from abduction to infraduction leading to impaired abduction and supraduction.
