Bell’s palsy that paralyzes eyelid

One disease that may affect eyes is named Bell’s palsy, which usually occurs suddenly and happens to one people out of 60. This disease acts much like a stroke, and the affected side of face can not move. The temporarily paralyzed facial nerve can not control the face and lip on the affected side.

This seventh cranial nerve also controls the movement of eyelid and muscles of the forehead and neck. So that people suffered from Bell’s palsy can not close the affected eyelid, which is turning outward. But the eye is still under control, since it is controlled by a separate cranial nerve.

Since the affected eyelid is out of control, tears in the affected eye accelerate to evaporate. As a result, severe dry eye will be caused, which is known as exposure keratitis. In this case, many people will patch the eyelid to keep it moist.

Before the onset of Bell’s palsy, some people may feel pain behind the ear. Ocular lubricants such as non-preserved artificial tears and eye ointments can be used to treat Bell’s palsy. With proper treatment, Bell’s palsy will recover within six months, otherwise consequential corneal ulceration and scarring may be left.
