Preseptal and Orbital Cellulitis Pathway Background and Objectives Orbital cellulitis is a relatively uncommon condition but carries significant morbidity, including orbital abscess, vision loss, cavernous sinus thrombophlebitis, and intracranial abscess. Orbital abscess is a surgical emergency. Though they have distinctly different pathogenesis, differentiating orbital cellulitis from preseptal (periorbital) cellulitis is often difficult, especially in younger children. Preseptal cellulitis is more common than orbital cellulitis and has less risk of serious complications. Preseptal cellulitis arises from a superficial infection of the skin and soft tissues in the periorbital region anterior to the orbital plate. The most common organisms implicated in preseptal cellulitis are Staph aureus, Strep pneumoniae, other Strep species, and anaerobes. In comparison, orbital cellulitis arises from sinusitis, most commonly from the ethmoid sinuses, with spread of infection and inflammation through the thin layers of the lamina papyracea. The most common causative agents of orbital cellulitis are Staph and Strep species, and less commonly anaerobes. Both orbital and preseptal cellulitis can cause periorbital edema, erythema, eye pain, and fever, and therefore can sometimes be difficult to distinguish clinically. Patients with orbital cellulitis are more likely to have pain with extra-ocular movements, restricted extra-ocular movements, diplopia, proptosis, and an absolute neutrophil counts (ANC) >10,000. If there is concern for orbital cellulitis, an urgent CT scan with IV contrast to evaluate for orbital abscess is necessary. If orbital cellulitis/abscess is suspected and/or identified, care coordination between multiple services including, Pediatric Hospital Medicine, ENT, and Ophthalmology is required. The objectives of this pathway are to: Quickly identify patients with orbital cellulitis who may require surgery Identify those patients who require a CT Scan Improve coordination of the multiple subspecialists often involved in care of this group of patients Standardize antibiotics for these infections Algorithm Download Preseptal and Orbital Cellulitis Pathway Algorithm – Updated March 4, 2022 Quality Metrics Percentage of patients with pathway order set usage Percentage of patients with ophthalmology consult Percentage of patients who have a CT scan Percentage of patients who have a CT scan with documented sxs of orbital cellulitis Percentage of patients who require surgery Percentage of patients with appropriate antibiotic choice per pathway recommendation Percentage of patients with appropriate antibiotic duration per pathway recommendation ED average length of stay (minutes) Inpatient average length of stay (days) Number of returns to ED within 48 hours Number of readmission within 48 hours Educational Module Download Preseptal and Orbital Cellulitis Educational Module – Updated March 4, 2022 Key References Rudloe TF, Harper MB, Prabhu SP, Rahbar R, Vanderveen D, Kimia AA.
