Schfrmer's test

Schfrmer's test is to check whether the tear secretion of the lacrimal gland is normal. Under normal circumstances, the lacrimal gland cannot be touched. Let the patient look under the nose and pull the upper condyle of the upper eyelid outward with the thumb of the opposite side as much as possible to expose the lacrimal gland of the eyelid that is swollen due to inflammation or tumor to the conjunctiva of the upper fornix of the outer condyle, so an examination.
