In Bell’s palsy, why does the affected eye sometimes brim with tears?

In Bell’s palsy, the affected eye may brim with tears due to separation of the punctum (the opening of the lacrimal duct) from the conjunctival surface. Contrary to what one might expect, lacrimation is often reduced in Bell’s palsy because of parasympathetic nerve involvement .
