A patient presents with unilateral facial nerve palsy causing inability to close the eye and excessive saliva drooling from one side of the mouth. Which of the following is NOT a direct consequence of this condition?

Facial nerve palsy causing lagophthalmos (inability to close the eye) can lead to corneal abrasion, exposure keratitis (dry eye from inability to blink), and difficulty sleeping due to eye irritation. These are direct mechanical consequences of incomplete eye closure. Glaucoma (elevated intraocular pressure) is not a direct consequence of facial nerve palsy or lagophthalmos — it results from impaired aqueous humor drainage and is not related to the inability to blink or drooling. Therefore, glaucoma is the correct answer to this 'NOT a consequence' question.
