Allergy: When local allergy occurs in the lower eyelids of infants, the permeability of local capillaries increases, and intravascular substances penetrate into the subcutaneous tissues, which can lead to swelling of the lower eyelids of the children, and can be accompanied by eyelid itching and other discomforts.
4. Mosquito bites: After mosquito bites on the lower eyelid skin of infants, generally localized red, doughnut-like papules can appear, so children can appear lower eyelid redness, swelling, itching and other discomforts.
