Orbital cellulitis
ICD-10 H05.0 · ICD-11 9A21.0
Treatment of Orbital Cellulitis with Intracranial Complication and Neurological Signs
Clinical Scenario
This protocol covers orbital cellulitis presenting with neurological signs that raise suspicion of intracranial spread. Complications in this setting include cerebritis, intracranial or brain abscess, epidural or subdural empyema, and meningitis.
When neurological signs are present in a patient with orbital cellulitis, intracranial extension must be suspected. Aggressive intervention is required, with a multidisciplinary approach involving oculoplastic surgeons, otolaryngologists, neurosurgeons, and infectious disease specialists.
Treatment Approach
The cornerstone of management is wide-spectrum antibiotic therapy with anaerobic coverage and strong CNS penetration, alongside measures directed at raised intracranial pressure. In the early phase of cerebritis — before abscess formation — prompt antimicrobial intervention may prevent further progression.
The complete antibiotic selection, combination strategy, and intracranial pressure management details are available in the full structured protocol.

- Penicillin, chloramphenicol, third-generation cephalosporins and metronidazole penetrate well into the intracranial space and combined are effective against most responsible pathogens.
- Mannitol, hyperventilation and steroids are also used for the increased intracranial pressure.
