For a patient experiencing Bell's Palsy, artificial tears are used to address which issue?

In the case of a patient experiencing Bell's Palsy, artificial tears are used primarily to address dry eye. Bell's Palsy is characterized by temporary weakness or paralysis of the muscles on one side of the face, which can affect the ability to blink and close the eye completely. This impaired ability to blink can lead to decreased tear production and inadequate eye moisture, resulting in dry eyes.

Artificial tears serve to lubricate the eye, providing relief from dryness and helping to protect the ocular surface from irritation or damage. This is crucial, as prolonged exposure of the cornea can lead to complications, including corneal abrasions or infections. Therefore, the use of artificial tears is a vital intervention in managing the symptoms associated with Bell's Palsy, particularly the dryness of the eye that can occur due to reduced eyelid closure.
