what nerve causes strabismus
There are many different types of strabismus. Strabismus is most commonly described by the direction of the eye misalignment; common types of strabismus are esotropia, exotropia, hypotropia, and hypertropia. Strabismus can also be described by its cause. The 3 cranial nerves (III, IV, VI) responsible for eye movement can be weak or palsied and cause strabismus. Some examples of paralytic strabismus include third nerve palsy and superior oblique palsy.
