Overview

Because of concern for spread of infection, patients must be admitted to the hospital to receive intravenous antibiotics. Orbital cellulitis is considered an ophthalmological emergency.

Prompt treatment is vital for a patient when fighting orbital cellulitis. Treatment typically involves IV antibiotics in the hospital and frequent observation (every 4-6 hours). Along with this several laboratory tests are run including a complete blood count, differential, and blood culture.

Medical Therapy

• Antibiotic Therapy - Since orbital cellulitis is commonly caused by Staphylococcus and Streptococcus species both penicillins and cephalosporins are typically the best choices for IV antibiotics. However, due to the increasing rise of MRSA (methicillin-resistant Staphylococcus aureus) orbital cellulitis can also be treated with Vancomycin, Clindamycin, or Doxycycline. If improvement is noted after 48 hours of IV antibiotics, healthcare professions can then consider switching a patient to oral antibiotics (which must be used for 2-3 weeks).
