Bell's palsy is a sudden, unexplained, paralysis of the facial muscles. This paralysis causes a drooping of one side of the face, i.e., one corner of the mouth sags, the lower eyelid sags on the same side, with resultant loss of the normal blink reflex. The loss of the eyelid blink and exposure of the eye by the drooping lid are potentially dangerous to the eye. The eye requires moisture provided by the tear film. The eyelids spread the tears and provide nutrients to the cornea and eye surface. Without a normal eyelid function and the tear film, the surface of the eye begins to dry out and die. Bell's palsy is most usually "self-limited," resolving without treatment over a period of weeks or months. Until condition resolves, it is important to lubricate the eye. Artificial tears and ointments are important to eliminate the possibility of drying the eye. Sometimes, taping the eyelids closed may be required to protect the eye's vulnerable surface. Sometimes, suturing of the eyelids together (tarsorrhaphy) is necessary to protect the eye. Usually, this is only temporary.
Blepharochalasis, Greek for "eyelid relaxation," is droopy or excess eyelid skin. It is characterized by recurrent episodes of painless swelling of the upper eyelids. The cause may be due to previous abnormal swelling, or heredity. In the case of aging, this may be called dermatochalasis. If the upper eyelid skin droops so that it blocks part of the vision, it is natural for the patient to unconsciously use the forehead muscles to lift the lids. Testing may be performed to determine the field of vision being blocked. This excess skin is often associated with drooping of the eyelid itself known as ptosis. Wrinkled skin folds above and below the eyes can produce an aging, sagging or tired look. If the drooping is not affecting your appearance or your vision, there is no need for treatment. Correction involves surgery called blepharoplasty under local anesthesia.
Blepharoclonus is an increase in reflex blinking or the duration of the blink is longer than usual. This condition may be initiated by irritation or inflammation of the cornea or the conjunctiva. Children may develop episodes of rapid involuntary blinking. Examination generally will not find a cause. In this case, if attention is removed from the child, the blinking typically decreases. When this condition develops in adults, it may also involve muscles of the face. This condition is usually not organic thus treatment is unnecessary.
Blepharospasm is a sudden, involuntary intermittent twitching of the muscles that surround the eye. This annoying twitching typically results from stress, anxiety, fatigue, lack of sleep and occasionally excessive use of alcohol or smoking. In some cases, it may result from increased caffeine consumption or from superficial irritation of the eye. Infrequently uncorrected refractive errors, eye-related factors cause of blepharospasm. Occasionally, oral decongestants containing antihistamines may reduce the annoying symptoms of this condition by relaxing the eyelid muscles. Better yet drink Quinine Water (tonic water), it may reduce or relieve the spasm. The muscle spasms are called blepharospasm.
