What should you know about impetigo under eye?

Impetigo can produce fragile blisters, shallow sores, and sticky yellow-brown crust on the eyelid or nearby skin. Similar changes can also come from irritation, eczema, allergy, or another infection, so a location near the eye should not be self-diagnosed from appearance alone. Atopic dermatitis can weaken the skin barrier; see Atopic Dermatitis for related background.

Crusting Skin explains why a crust is a visible skin change rather than a diagnosis by itself.

Wash your hands before and after care. Use clean lukewarm water to soften discharge on the surrounding skin, wiping outward with a fresh clean pad each time; do not scrub. Avoid contact lenses, eye makeup, adhesive products, and sharing towels. Do not use a skin cream inside the eye or on the eyelid unless a clinician specifically directs you. A clinician can decide whether Topical Antibiotic Therapy is suitable or whether Antibiotics For Skin Infection are needed.

Seek same-day medical advice for suspected impetigo close to the eye. Get urgent help for eye pain, pain when moving the eye, vision change, marked eyelid swelling, fever, severe headache, or redness spreading around the eye. These symptoms need assessment because they may indicate deeper involvement rather than a simple surface sore.

Ask whether the eye itself is involved, which cleanser and medicine are safe near the eyelid, how to prevent spread at home, and what change should trigger urgent review.
