User:Mr. Ibrahem/Periorbital cellulitis

Periorbital cellulitis, also known as preseptal cellulitis, is an infection of the eyelid and tissue anterior to the orbital septum. Symptoms may include a tender, red, and swollen eyelid. Fever is less commonly present. Vision should be normal and movement of the eye should occur without difficulty. Complications are rare, though occasionally include orbital cellulitis.

It typically occurs following a breaks in the skin around the eye, such as from scratching or an insect bite. It may also occur as a complication of a chalazion or sinusitis. Diagnosis is based on symptoms, with medical imaging done in unclear cases.

Those with mild disease may be treated with antibiotics by mouth such as amoxicillin/clavulanate for 7 to 10 days. Clindamycin or trimethoprim/sulfamethoxazole may be added if MRSA is a concern. With treatment, it should resolve within a week.

Periorbital cellulitis is relatively common in comparison to orbital cellulitis. Children are more commonly affected than adults. In children it represents about 85% of swelling around the eye. While the term could mean any swelling around the eye, it is technically only used for cases related to infection.
