In children with red eyes and eye drops, this happens mostly due to the occurrence of eye inflammation in the child. For example, infectious conjunctivitis, keratitis, blepharitis, inflammation of the tear duct and lacrimal sac, or entropion and impingement. The treatment of infectious inflammatory conditions requires a clear definition of what is causing the condition before it can be treated with symptomatic and targeted medications to obtain good results. For example, bacterial infections in conjunctivitis, viral infections, fungal infections that may be present in keratitis, or parasitic or helminthic mite infections in blepharitis. In addition, there are some conditions that require the removal of the triggering factors before the subsequent use of medication to reap the benefits, such as tear duct and lacrimal sac inflammation, which requires the removal of the lacrimal duct obstruction or narrowing, and entropion, which requires the removal of the entropion of the eyelid and the irritation of the conjunctiva by the eyelashes before the targeted medication can be used to relieve the problem. Therefore, in the case of children with red eyes and eye drops, it is important not to blindly intervene with drugs in a homogeneous manner, but to make an accurate assessment of the mechanism of the disease, the nature of the infection, and the extent of the disease before developing targeted measures and methods to obtain the ideal response, and to adhere to the treatment in the ophthalmology department of a regular hospital.
