Preseptal cellulitis

Preseptal cellulitis (also known as periorbital cellulitis) is an infection of the eyelid and surrounding skin, which is located anterior to the orbital septum. It is a common and potentially serious infection in children.

Causes

Preseptal cellulitis is often caused by bacteria, including Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae. It can also be caused by trauma to the eye area, such as a bug bite or scratch.

Symptoms

Symptoms of preseptal cellulitis include redness, swelling, and warmth of the eyelid and surrounding skin. There may also be pain, tenderness, and a feeling of heat in the affected area. In severe cases, the infection can spread to the eye itself, causing conjunctivitis or keratitis.

Diagnosis

Diagnosis of preseptal cellulitis is usually based on the patient's symptoms and a physical examination. In some cases, a CT scan or MRI may be used to confirm the diagnosis and rule out other conditions, such as orbital cellulitis or an abscess.

Treatment

Treatment for preseptal cellulitis typically involves antibiotics, either taken orally or given intravenously. In severe cases, hospitalization may be required. If an abscess is present, it may need to be drained surgically.
