Pediatric preseptal cellulitis: what parents should know

Preseptal cellulitis, also called periorbital cellulitis, involves tissues in front of the eye socket. It may cause eyelid swelling, warmth, redness, and tenderness, often on one side, with or without [Fever](/symptoms/fever/). Children can develop it after a local skin break, bite, sinus infection, or another nearby infection. The eye itself should move normally and vision should remain clear; pain with movement, reduced vision, or a bulging eye raises concern for deeper orbital infection. The general [Cellulitis](/conditions/cellulitis/) guide provides further background.

Have the child assessed promptly so a clinician can examine the eyelids, eye movements, vision, temperature, and general appearance. The recommended antibiotic and treatment setting depend on the examination, age, underlying health, and ability to take medicine. Follow the prescription schedule carefully and do not stop early because the swelling looks better. Avoid pressing on the eyelid, applying unapproved creams, or using someone else’s antibiotics. Track whether redness, swelling, tenderness, fever, and alertness are improving, and report deterioration without delay. Mention recent scratches, insect bites, sinus symptoms, or recurring skin infections during the visit.

Seek emergency care for pain or restriction when the child moves the eye, blurred or double vision, a bulging eye, severe headache, vomiting, confusion, or unusual drowsiness. Rapidly increasing [Skin Swelling](/symptoms/skin-swelling/), spreading [Skin Redness](/symptoms/skin-redness/), persistent fever, poor drinking, or a child who looks very unwell also warrants urgent help. These features may signal extension beyond the preseptal tissues or a serious systemic infection.

Ask how the examination distinguishes preseptal from orbital cellulitis, which medicine and dose are prescribed, and when the child should start improving. Ask how to monitor eye movement and vision at home, when follow-up is needed, and what should prompt an immediate return.
