Fever in babies with redness around the eyelids is mainly due to the invasion of viruses, bacteria, mycoplasma, chlamydia and other pathogens in the body, causing an inflammatory response in the body, and the capillaries of the skin around the eyes become congested, edematous, or even ruptured and red. Blood tests can be performed to clarify the cause of the disease, and attention should be paid to keeping the baby warm and avoiding exposure to cold. Also pay attention to protecting the baby’s eye area as well as the eyeball to prevent the baby from picking the skin around the eye by itself and causing infection. You can also apply erythromycin eye ointment to prevent infection from occurring. Give your baby appropriate Chinese medicine to clear heat and detoxify the toxins, and keep a follow-up appointment.
