Sixth nerve palsy, or abducens nerve palsy, is a disorder associated with dysfunction of cranial nerve VI (the abducens nerve ), which is responsible for causing contraction of the lateral rectus muscle to abduct (i.e., turn out) the eye. [ 1] The inability of an eye to turn outward, results in a convergent strabismus or esotropia of which the ...

People with exotropia often experience crossed diplopia. Intermittent exotropia is a fairly common condition. "Sensory exotropia" occurs in the presence ...

Brown syndrome is a rare form of strabismus characterized by limited elevation of the affected eye. The disorder may be congenital (existing at or before birth), or acquired. Brown syndrome is caused by a malfunction of the superior oblique muscle, causing the eye to have difficulty moving up, particularly during adduction (when eye turns ...
Strabismus can occur due to problems with the muscles and nerves that control the eyes, as a side effect of an eye injury or other medical condition, or as a complication from significant far ...
