Treatment is with antibiotic ointment until the abrasion has healed, unless the abrasion is over the pupil, in which case your child should probably see an ophthalmologist. Children with allergies can develop allergic conjunctivitis , which causes both eyes to be red and swollen, itching and tearing. Antihistamines or eye drops may be needed for treatment. A stye or hordeolum produces a tender, red swollen area on your child's eyelid. It may point inward or it may be on the outside of the eyelid margin.
Treatment is with warm compresses and sometimes topical antibiotics.
If there is a nodule or swollen area, but it isn't tender, then it is probably a chalazion , which is an inflamed meibomian gland that improves by using warm compresses several times each day for several weeks or months. Persistent cases sometimes require excision. Blepharitis is an inflammation of the eyelids that causes them to have redness, crusting and scaling and the eyes may be itchy or irritated. Treatment is usually with daily cleansing of the eyelids with a no-tears shampoo and a soft cloth. Sometimes an antibiotic cream is also needed.
