What should you know about causes of orbital cellulitis?

The infection may follow sinusitis or spread from an infection on the face. A cut, insect bite, surgical wound, or foreign material can provide an entry point. Skin infections such as cellulitis, including infection near the nose or eyelids, may extend deeper. Athlete's foot can be relevant when it is part of a broader pattern of skin breakdown, but it does not by itself prove the source. People with diabetes or reduced immune defenses may need especially prompt evaluation.

Orbital cellulitis is not suited to home treatment or watchful waiting. Contact emergency medical services or go to an emergency department for suspected symptoms. Clinicians may examine eye movement and vision, assess the sinuses, and give treatment that reaches a deep infection. Do not squeeze swollen skin, use leftover antibiotics, or delay care while trying topical products.

Get urgent help for a swollen or red eyelid with fever, significant eye pain, pain when moving the eye, reduced or double vision, a bulging eye, severe headache, vomiting, confusion, or rapidly worsening swelling. A serious infection can threaten vision and may spread beyond the eye socket, so urgency is driven by these warning signs rather than by how common the condition is.

Ask whether the infection may have come from the sinuses, skin, or an injury; whether imaging is needed; and how vision and eye movement will be monitored. Tell the team about diabetes, immune conditions, recent procedures, injuries, and any antibiotics already taken.
