It is the infection of the eyelid and the periocular skin in front of the septum and orbital cellulitis, behind the orbital septum. Both types of cellulitis can be caused by an external source of infection (e.g., a wound), by infections that spread from the sinuses or teeth, or by metastatic spread of infections in other parts of the body. Symptoms include pain, erythema and eyelid edema, fever, malaise, exophthalmia, impaired ocular mobility, and visual disturbances.

Treatment: Amoxicillin / clavulanate is the antimicrobial of choice in the initial treatment of children. Other alternatives are cefuroxime or the combination of cloxacillin and cefotaxime.
