Babies have big eyes that are bright, innocent and loved by everyone. But even when the child is not crying or teary-eyed, non-stop tears, this time parents can not be careless, it is likely to be the baby’s eyes out of the problem. It is normal for children to cry or have their eyes stimulated by the outside world, and to secrete more tears, but if there is no reason for tears, it may be related to the following diseases. A, neonatal lacrimal sacitis neonatal lacrimal sacitis is the most common cause of pediatric lacrimation, children suffering from this disease basically after birth (before the full moon) that lacrimation symptoms, in the lacrimation at the same time, some children also accompanied by thick yellowish secretions out, especially in the morning when you wake up, eye droppings, generally single-eye disease, but the onset of both eyes is not uncommon. Parents can determine this in a simple way: press the skin of the inner corner of the eye (tear sac area) with their fingers and see yellowish pus coming out of the corner of the eye. The treatment of this disease is mainly to massage the skin of the lower part of the large corner of the eye (the lacrimal sac area) to encourage the opening of the lower nasolacrimal duct, with antibacterial eye drops (such as tobramycin eye drops, colistin eye drops, telbivudine eye drops) spot eye. With the child’s own development and with massage therapy, some children with neonatal dacryocystitis can be cured. If the above treatment does not work, those aged 3-5 months (some doctors advocate an age greater than 7 months or even 10 months) can be treated with lacrimal duct irrigation or probing and, if necessary, lacrimal duct placement. The majority of neonatal dacryocystitis is mainly due to the lower end of the baby’s nasolacrimal duct not yet fully developed, and is closed by a layer of residual membrane causing lacrimal obstruction and secondary bacterial infection, resulting in lacrimation and pus, so do not worry too much, the current treatment can be a good solution to this problem does not leave any sequelae. In yellow people, the inner eyelashes of the lower eyelid flip inwards and the eyelashes fall back onto the surface of the eye, stimulating the cornea (black eye) and the bulbar conjunctiva (white eye) and causing tearing. This condition is also more common and usually occurs in both eyes at the same time. This condition is usually accompanied by increased blinking, inattentiveness, and rubbing of the eyes with the hands. However, it does not usually occur before the child is full term, because the eyelashes of a newborn child are soft, but as the child grows the eyelashes gradually become harder and the irritation gradually increases. Parents can look closely at their child’s eyes and see that the eyelashes fall onto the eyeball and rub the surface of the eye like a brush, the white eye is red and bloodshot, and in severe cases, the surface of the black eye is even cloudy like hairy glass. If corneal ulceration is secondary, white spots on the surface of the black eye can be seen. In cases where the eyelash inversion is not obvious and the irritation is not severe, observation can be done and regular review at the hospital ophthalmology department (usually once every 3 to 6 months) is sufficient. Some children will resolve on their own as the nasal bones develop further, but if the irritation is still severe, the eyes are very teary and red, and the corneal surface already has white spots, then lid entropion correction surgery must be done to treat the condition. The surgery is relatively simple and most cases do not require a skin incision and can be corrected with only sutures, without any effect on appearance. This is a hyper-acute bacterial conjunctivitis caused by gonococcal infection, also known as “gonococcal conjunctivitis” in medicine. This disease was more common before liberation, but in recent years, the number of such patients in the clinic has gradually increased, and there is a trend of resurgence, worthy of caution. The onset is usually 2 to 4 days after birth and is characterized by watery eyes, photophobia, high edema of the eyelids and the surface layer of the white eyeball (conjunctiva), a large amount of yellow purulent secretions flowing from the lid fissure, and difficulty in opening the eyes. In severe cases, corneal ulceration can occur within a few days or even hours, which can seriously affect vision and even lead to blindness due to perforation of the corneal ulcer and total uveitis, and may also be complicated by purulent inflammation in other parts of the body, such as dacryocystitis, arthritis, meningitis, pneumonia, sepsis, etc. The general difference between this disease and neonatal lacrimal sacculitis is that septicemia mostly occurs in both eyes at the same time, the eyelids and conjunctiva are red and edematous, and there is more eye discharge than in lacrimal sacculitis, in the words of parents, “just wiped clean for a few minutes and then there is again”. The condition of neonatal ophthalmoplegia is dangerous and progresses rapidly. So parents must be vigilant and treat it early. This disease is mainly caused by the contamination of the vaginal discharge of the mother with gonococcal vaginitis at birth, so the treatment is mainly anti-gonococcal. At present, the treatment is mainly frequent flushing to remove purulent discharge, frequent local drops of penicillin solution, 0.3% ofloxacin eye solution (once in 30 minutes in acute stage), and oxyfloxacin eye ointment or erythromycin eye ointment for eyes. Systemic medication is given as 100,000 single penicillin per kilogram of body weight per day intravenously or intramuscularly in 4 doses for 7 days. Parents’ cooperation in treatment is also important. Once a newborn is found to have pus leaky eyes, both parents should receive formal examination and treatment to eliminate the source of infection and cut off the transmission route.
