Children with yellow and sticky eye boogers who can’t open their eyes should be treated according to different causes, which may be bacterial conjunctivitis or dacryocystitis. Bacterial conjunctivitis is an inflammation of the conjunctival tissues of the eye caused by bacteria in the external environment that infect the eye when the child does not pay attention to eye hygiene and rubs the eyes with dirty hands. Dacryocystitis is caused by an obstruction of the tear ducts, which leads to the accumulation of tear fluid in the tear ducts and bacterial infection. Both need to be treated with antibiotic eye drops, such as moxifloxacin eye drops and tobramycin eye drops, which are safe for children. Medications should be used as prescribed by your doctor. In children with dacryocystitis, after the acute inflammation is eliminated through the use of eye drops, the tear ducts usually need to be unblocked through surgery, such as transcutaneous lacrimal sac nasolacrimal anastomosis or endoscopic lacrimal sac nasolacrimal anastomosis, and so on. Patients should go to the ophthalmology department of the hospital for examination in time, and after a clear diagnosis, the doctor will formulate a reasonable treatment plan.
