During the winter holiday season, I often see children in the ophthalmology clinic who are brought in by their parents because of frequent blinking. The parents of these children are very interested in learning more about this issue, so they often ask me a lot of questions. Here we will talk about the common causes of frequent blinking in children and how to treat it. Under normal circumstances, people blink an average of 15 to 20 times per minute. Blinking normally distributes the tear film across the surface of the eye, which protects the cornea, prevents the surface of the eye from drying out, and prevents damage from dust, but frequent blinking is a pathological phenomenon. The common causes of frequent blinking in children are: 1. Inflammatory irritation: This is the most common cause, and may be due to bacterial, viral, or chlamydial infections such as conjunctivitis and keratitis. In addition to increased blinking, there are manifestations such as red, itchy eyes, increased secretions, and tearing. For the treatment of frequent blinking caused by bacterial inflammatory irritation, tobramycin eye solution or 0.1% rifampin eye solution can be used to spot the eyes 3 to 6 times a day, and erythromycin and other antibiotic eye ointments can be applied to the eyes once a night. In severe cases, the number of eye drops can be increased to once every 1 to 2 hours. If the inflammation is caused by a virus, use acyclovir or antabuse ophthalmic solution to spot the eyes every 1 to 2 hours. In severe cases, systemic medication is required for treatment. 2. Congenital eyelid entropion and inverted eyelashes: Some children have congenital entropion of the eyelid (medically called eyelid) because the eyelashes are inverted on the surface of the eye and irritate the cornea (the surface of the black eye) causing tearing. This condition is the most common with an entropion of the eyelid and can be detected by attentive parents. For treatment, in mild cases, the eyelid can be gently turned out to its normal position and fixed by traction with tape applied to the local skin, and as the child’s body develops, the entropion is expected to heal on its own. In severe cases, surgery is required to correct the problem. Hyperactivity in children: This refers to sudden, involuntary contractions of a part of the child’s body, such as blinking, wrinkling of the forehead, crooked mouth, shrugging of the shoulders, etc., as well as inattention and changes in hyperactive behavior. Some children also make strange noises and even curse and swear, a condition medically known as hyperactive obscene language syndrome in children. The cause of this condition is still unknown, but it may be related to psychological factors, such as mental stress and emotional instability. This disorder seriously affects the normal life, learning and mental health of children. The treatment is mainly based on behavior modification, parents should cooperate with the doctor to remind the child to help self-control, but not too hasty, do not reprimand the child scold, need to gradually induce, patient persuasion. 4, eye fatigue blinking: including visual fatigue such as refractive error, especially farsightedness, myopia, astigmatism is not corrected causing eye visual fatigue and caused. This is a protective reflex, by constantly blinking can adjust the curvature of the eye, so that visual clarity. In this case, you should arrange your child’s school life appropriately, tell your child that the time spent reading books, watching TV and computers should not be too long, urge your child to do eye exercises, and get glasses if necessary. 5, neurological blinking: due to frequent contraction of the nerve fibers that govern the orbicularis oculi muscle after being stimulated. The treatment can be local massage and hot compresses, internal sedatives such as Bachmann’s compound and tribromo tablets. You can also use neurotrophic agents such as vitamin B1, B2 inosine and other drugs. 6, habitual blinking: Some children have a history of frequent blinking due to one of the above causes, and through treatment, they retain the habit of frequent blinking after the cause is removed. Other children like to imitate other people’s blinking because they usually don’t pay attention to it, resulting in habitual frequent blinking. Parents should remind their children to help them control themselves. In short, there are many different causes of frequent blinking in children, and treatment varies, requiring diagnosis and treatment by an experienced physician. Parents should seek medical attention as soon as they notice their child blinking frequently to avoid aggravation of the disease. As long as they are detected and treated in a timely manner, the results are generally good.
