For instance, many of us expect bad backs, achy joints, poor memory, and being hard of hearing. In such cases recession of the medial rectus of the affected eye is accompanied by recession and/or posterior fixation (Fadenoperation) of the contraleral medial rectus. Partial lateral rectus function is associated with a smaller primary gaze esotropia and retained ability to abduct to the midline and beyond (Figure 7), but the preservation of some sixth nerve function raises the possibility of other confounding diagnoses (Table 3).

Most patients can be expected to recover in 1 to 4 months. In 3 to 4 weeks, if recovery has not begun, assess the extent of the nerve damage by electromyography. If no neurologic recovery is observed in 3 to 4 months, we explore the nerve palsy may have complications. Whilst this is a positive adaptation in the short term, in the long term it can lead to a lack of appropriate development of the visual cortex giving rise to permanent visual loss in the suppressed eye; a condition known as amblyopia or Lazy eye.
