A child’s body is constantly changing from birth to adulthood (around the age of 18), and so are his eyes, so they need to be seen by a professional pediatric ophthalmologist. Common childhood eye diseases include: strabismus, amblyopia, refractive errors – myopia, hyperopia, astigmatism; neonatal lacrimal sacculitis, conjunctivitis, keratitis, etc.; congenital ptosis, congenital cataract, congenital glaucoma, hereditary eye disease and retinopathy of prematurity. Since young children cannot express their senses accurately, many eye diseases depend on parents’ careful observation. If the following conditions are found, your child may have an eye disease and should be examined at the hospital in time: cannot look at the object in front of him/her or cannot turn his/her eyes after the light; when covering one eye, the child When one eye is covered, the child does not respond, and when the other eye is covered, the child may become irritable and cry, indicating monocular visual impairment or amblyopia. If the child likes to look at things with a crooked head (crooked neck), close one eye in the sunlight, or look at the target with one eye and deviate from it with the other eye (inconsistent vision of both eyes), it is mostly a sign of strabismus. If you look at books and TV at a close distance and squint, you may have poor vision and refractive error (hyperopia, myopia, astigmatism, etc.). Involuntary swaying of the eyeballs, medically known as nystagmus. Babies have tears soon after birth, even white mucous or yellow purulent discharge, it is caused by poorly functioning nasolacrimal ducts. When the nasolacrimal duct is blocked the tears are trapped in the tear sac and once infected the tears turn into pus. When encountering this situation, parents should give the child massage and point antibiotic eye drops, if the baby has been more than 2 months, and by the above conservative treatment is not effective, it is feasible to tear duct flushing to understand the specific site and degree of obstruction, the use of tear duct exploratory surgery, so that the tear duct is open. Red eyes, eye discharge, is mostly a manifestation of conjunctivitis, if every spring and summer episodes, and even have frequent sneezing symptoms to pay attention to whether it is allergic inflammation. If you have photophobia and tearing, pay attention to exclude congenital glaucoma, entropion, inflammation of the cornea and other eye diseases. White pupils, i.e., white or yellow-white reflections in the pupil area that should be black, are commonly referred to as “cat’s eyes” and may be due to congenital cataracts, retinoblastoma, retinopathy of prematurity, and pediatric hereditary fundus disease. Since children’s eyes have their own developmental characteristics, the performance and treatment of eye diseases are not the same as those of adults, so from the perspective of children’s eye care, they should go to a professional pediatric ophthalmologist for a general checkup in three to six months. For the diagnosis and treatment of various common eye diseases in children, it is important to follow the advice of a professional pediatric ophthalmologist, and the abuse of various antibiotic eye drops is highly undesirable.
