Parents often ask how to choose eye drops for children, especially for infants and toddlers. Eyes are delicate, and the eyes of infants and children are especially delicate. There are two misconceptions when it comes to choosing eye medications for various eye diseases: a high level of fear and skepticism of any eye medication, and the use of medication like adults. For many eye diseases, eye drops are the direct disposition of the curative effect, because the concentration of drugs that reach the eye through the blood circulation is very low or even does not work, so the role of eye drops is irreplaceable by other means of medication. Many parents are afraid to give their babies eye drops, in fact, eye medication as long as the indications are mastered, generally will not cause harm to the eye and the whole body, many instructions listed side effects are speaking of oral, intravenous medication and other side effects, for example, tobramycin eye solution (Tobex) is used all over the world to children, but systemic use has the risk of deafness. For children, gels are a good choice to reduce the number of eye drops used and to avoid the “blurred vision” caused by eye ointments. The following is a description of several issues of particular concern to parents. 1) Preservatives. Many eye drops have preservatives or preservatives in order to keep them for a long time. For children who use eye drops for a long time, preservatives have a destructive effect on the tear film of the eye surface, resulting in corneal spotting and dry eye syndrome. (2) Drug toxicity issues, infants and children should use chloramphenicol eye drops with caution, because it is easy to cause blood system problems in sensitive children. For antiviral eye drops, because of the corneal toxicity effect, it is recommended to stop the drug in time after the symptoms are controlled. Glucocorticoid eye drops have the effect of raising IOP and are recommended for short-term use. In addition, low-concentration hormone eye drops (such as Flomethol) have low side effects, both anti-inflammatory and non-significant effects on raising IOP. (3) Antimicrobial resistance problems. Bacterial infections such as conjunctivitis and keratitis can be effectively prevented by doing bacterial culture and drug sensitivity tests before treatment. 4) The effect of pupil dilating agents on IOP in children. Generally speaking, the diseases that cause elevated IOP with pupil dilators are closed-angle glaucoma. Glaucoma in children and adolescents tends to be open-angle, which has a limited effect on elevated IOP, and there is little cause for alarm. 5) Age of use. Generally used strictly according to the instructions. In special cases, the doctor to the child’s parents to analyze the advantages and disadvantages of using a drug, careful use of mo an eye drops. Such as anti-allergy eye drops, some regulations in the 2 or 3 years of age or older, if the child’s allergy symptoms are particularly heavy, the use of other drugs have poor results, you can use a certain eye medication, but to closely monitor. It should be noted that almost all over the world, drug clinical trials on children are prohibited, so all drugs for children are used in adults for a good period of time to accumulate a lot of lessons learned before using them on children, so most drug instructions are written with caution for children.
