Blinking is a bodily function; it is a semi-autonomic rapid closing of the eyelid. A single blink is determined by the forceful closing of the eyelid or inactivation of the levator palpebrae superioris and the activation of the palpebral portion of the orbicularis oculi, not the full open and close. It is an essential function of the eye that helps spread tears across and remove irritants from the surface of the cornea and conjunctiva.
Eye blinking symptoms may accompany other symptoms, depending on the underlying disease, disorder or condition. Symptoms that frequently affect the eye may also involve other body systems.
Eye blinking symptoms may accompany other symptoms affecting the eye including:
Blurred or double vision
Discharge from the eye
Drooping eyelid (ptosis)
Dry eyes
Exposure of the ocular surface (lack of adequate wetting due to deficient blinking)
Eye pain
Eye muscle palsy (strabismus)
Increased sensitivity to light
Itchy eyes
Pain with blinking (usually severe)
Red, sore eyes
Squinting
Watery eyes
Eye blinking symptoms may accompany symptoms related to the nervous system including:
Disruptive outbursts of speech or gesture
Facial paralysis
Facial tics, including grimacing and twitching of the mouth and nose
Facial weakness
Lack of facial expression (called flat affect), or staring
Restlessness
Seizures and tremors
Shuffling gait (shuffling walk)
Slowed muscle movements
Slurred speech
In some cases, eye blinking symptoms may be a symptom of a life-threatening condition such as stroke that should be immediately evaluated in an emergency setting. Emergency care is also needed if eye blinking symptoms are caused by contact with a caustic chemical.
Abnormal pupils (fixed, dilated, unresponsive to bright light)
Burning or pain after contact with toxic substance
Change in level of consciousness or alertness, such as passing out or unresponsiveness
Facial paralysis
Facial weakness
Neck stiffness
Sudden change in vision, loss of vision, or eye pain
Sudden loss of balance or coordination
Sudden severe, unexplained headache
Most commonly, increased eye blinking results from eye irritation caused by bright light, dust, smoke, or a foreign body in the eye. Allergies, infections, and dry eye may also increase the rate of blinking. Conditions of stress, anxiety or fatigue may lead to increased blinking. Increased blinking, especially in young children, always deserves careful evaluation. Oftentimes it may only be a type of facial tic. On the other hand, increased blinking and light sensitivity are familiar findings in congenital glaucoma.
Eye blinking symptoms may also be caused by conditions occurring in the nervous system.
A severe decrease in blinking is seen chiefly in Parkinson’s disease, a brain disorder that impairs movement and coordination.
Eye blinking symptoms may be caused by specific disorders or injuries to the eyeball or eye orbit itself including:
Eye blinking symptoms can also be caused by neurologic disorders including:
Attention deficit disorder
Blepharospasm (involuntary spasm or twitching of the eyelid)
Dystonia
Facial tic
Parkinson’s disease (brain disorder that impairs movement and coordination)
Stroke
Tardive (slow or belated onset) dyskinesia
Tourette’s syndrome
In some cases, eye blinking symptoms may be an indication of a serious or life-threatening condition that should be immediately evaluated in an emergency setting. These include:
Aicardi syndrome (rare organic brain disorder acquired in early childhood)
Congenital glaucoma
Seizure disorder
Stroke
Because eye blinking symptoms can be due to serious diseases, failure to seek treatment can result in serious complications and permanent damage. Once the underlying cause is diagnosed, it is important for you to follow the treatment plan that you and your health care professional design specifically for you to reduce the risk of potential complications including:
Agaricus : Agaricus is indicated for twitching, jerking, quivering and spasms of the eyelids. The spasms are frequent where eyelids open and close numerous times a day. The twitching may be most worse while reading. Sensitivity to light may also be noted with above. Sometimes watering from eyes appears with spasms and twitching of eyelids.
Zincum Met : Zincum Met is a beneficial medicine for treating twitching of eyelids. Upper eyelids tend to feel heavy. Intense fatigue and weakness is a prominent attending feature. Zincum Met is a great nervous remedy and is also indicated for the treatment of facial twitches and tics in addition to twitching of eyelids.
Physostigma : Physostigma is prepared from the bean of a plant Physostigma venenosum commonly known as calabar bean of the natural order Leguminosae. Physostigma is helpful for cases of blepharospasm, twitching of eyelids attended with blurred vision. The contraction in lids makes it difficult to open the eyes. Pain in eyes from moving them may also appear in a few cases.
Euphrasia : Euphrasia is prepared from a plant Euphrasia Officinalis commonly known by the name of eye-bright of the natural order Scrophulariaceae. Euphrasia is helpful for cases of blepharospasm when photophobia (sensitivity to light) attends spasm of lids. Euphrasia is also useful for twitching eyelids cases linked with pink eye/conjunctivitis. In such cases, redness, discharge, itching, grittiness in eyes is also prominent.
Magnesia Phos : Magnesia Phos is another excellent medicine for treating eyelid spasm and twitches. Squinting may be present with this. Sensitivity to light, photophobia may also be present. Increased lachrymation, tired eyes and blurred vision are some other symptoms that may be present.
Codeinum : Codeinum is a well-indicated medicine for eyelid twitching that appears while reading and writing. The twitching appears in both the eyelids in cases needing Codeinum. Rubbing eyelids may help to relieve the eye twitching.e.t.c
