(1) Ocular inflammatory diseases: These are mainly caused by ocular surface diseases, such as conjunctivitis, punctate keratitis, and impingement. It should be noted that allergic conjunctivitis is common in children during the spring and summer months and is the main cause of blinking in inflammatory eye diseases. This type of child accounts for about 15% of blinks. (2) Dry eyes and visual fatigue: These children account for the majority of blinks, about 70%. During the summer vacation, children watch TV, use computers, play mobile games and watch movies on mp4, leading to excessive eye use. Prolonged eye use will not only lead to visual fatigue and dry eyes, but also to myopia. Therefore, parents must let their children form good eye habits, which is the key to treating blinking. (3) Refractive error: A small number of children with blinking have a relationship with refractive error, such as astigmatism and cryptopia, so most children with blinking need an optometry in order to identify the cause. (4) Bad habits: children are in a sensitive period of neurological development and are prone to blink because of the stimulation of external factors (such as inflammation, impingement, foreign bodies, etc.) Bad habits, parents must not be overly concerned about the child blinking to avoid adding to the child’s mental burden (the more you remind them not to blink the less likely they are to forget). As long as the parents “turn a blind eye”, the child will generally be relieved naturally in 1 to 2 months. (5) Tourette’s syndrome: about 10%, which is characterized by blinking accompanied by shrugging nose, frowning, the corners of the mouth up, lifting shoulders and other actions; some children even cursing, swearing. These children are associated with family conflicts, parents’ eagerness to see their children grow up, mental stimulation or tension, and emotional depression. It is important to visit a neurologist in a timely manner. It should be noted that the cause of blinking is not a single cause, but a combination of the above-mentioned causes. Therefore, comprehensive treatment is needed, including reducing the child’s mental and psychological burden, forming good habits of living with the eyes, reasonable nutrition and reasonable use of medication. Most of the children can be cured by local eye spotting, but for children with tic disorders or those who do not recover after a long period of time, they can be treated with traditional Chinese medicine and acupuncture. Severe tic disorders also require neurological consultation.
