Bell’s Palsy- How It Affects Your Eyes?

Are you facing difficulty in the movement of your eyelid? Have you heard about Bell’s palsy? It appears similar to a stroke. When the seventh cranial nerve known as facial nerve suffers paralysis or temporary weakness, it is referred as Bell’s palsy. It can occur slowly or even all of a sudden. Usually, it happens suddenly. The facial nerve that travels from the brain to face gets affected in Bell’s Palsy. This nerve is responsible for facial expressions, controls eyelid movement, and also the muscles of the neck and forehead. 

Cause of Bell’s Palsy

When Bell’s palsy strikes you, it substantially affects one side of the face. Usually, the cause is unknown, but certain viruses like herpes zoster and herpes simplex are associated with it.

It is also linked to diabetes, Lyme disease, sarcoidosis, infections, illness, viral infection, and trauma to the skull or face.

Effects of Bell’s palsy On Eyes

The disease makes it difficult for you to blink on the side that is affected by it. As the eye doesn’t blink normally, it becomes moist because enough tears are not spread. This results in making eye dehydrated, which in turn begins the formation of dry spots. The eye becomes dry and inflamed, increasing chances of keratitis. It occurs when the cornea is continuously exposed to moisture. The condition can worsen if left untreated. Your eyes can develop ulceration, scarring, and can even cause blindness.

Your lower eyelid also turns outward, and your face and lips become droopy; leaving you with no or at times little control on the functioning of muscles. You won’t observe any difficulty while opening the eye. The problem occurs when you try to close it; this, in turn, gives you a dry eye. You can also experience excessive tearing and blurred vision.
