II. Pathophysiology
- Preseptal Cellulitis is a Eyelid soft tissue infection
- Thin fibrous, septal membrane extends from orbital rim to lid margin
- Forms a periosteal extension or septum that prevents extension or lid disease to orbit
- Preseptal Cellulitis infections form anterior to the fibrous septum
- Contrast with Orbital Cellulitis which involves the deeper tissues (esp. ethmoid or Maxillary Sinusitis)
III. Epidemiology
- Typical onset at age 18 months to 3 years
IV. Causes
- Local Eyelid disease
- Eyelid Trauma (e.g. Insect Bite) with secondary infection (e.g. Impetigo)
- Dental abscess or infection with local spread
-
Sinusitis with local extension
- Uncommon in Preseptal Cellulitis
- Sinusitis is usually precursor to Orbital Cellulitis
V. Organisms
- Trauma
- Bacteremia (less common with modern Immunizations)
VI. Symptoms
- Acute Swollen Red Eyelid
- No fever
- No orbital pain or Extraocular Movement pain
- Contrast with painful Extraocular Movements in Orbital Cellulitis
VII. Signs
- Periorbital rash
- Pink, violaceous swelling of lid margins
- Multiple features differentiate Periorbital Cellulitis from the worrisome Orbital Cellulitis
- No Extraocular Movement pain or weakness (Ophthalmoplegia)
- No Proptosis
- Normal Vision
- Normal pupil reflexes
- No Conjunctival injection (Conjunctivitis)
- No cells and flare (Iritis)
- No limitation or pain on eye movement
- No Chemosis
- No retrobulbar globe pressure
- No Papilledema
VIII. Differential Diagnosis
- See Eyelid Inflammation
-
Orbital Cellulitis
- Inflames or entraps extraocular Muscles with painful or reduced Extraocular Movement
- May be associated with Diplopia and disconjugate gaze
IX. Management
- Admit all cases of Orbital Cellulitis
- Typical Preseptal Cellulitis may be treated outpatient with oral Antibiotics and close interval follow-up
- Close observation to rule out Orbital Cellulitis
- Hospitalize and treat Parenterally with broad spectrum Antibiotics if evidence of bacteremia or toxicity
- See Orbital Cellulitis
- Lumbar Puncture if suspect bacteremia source
- Antibiotic Course: 10 days
- Two Antibiotic regimen is controversial
- Sanford recommends starting with two agents, the second agent for added MRSA coverage
- Uptodate recommends single drug empiric coverage starting without MRSA (which they note is uncommon)
- Antibiotic 1 (choose one): Primary Preseptal Cellulitis coverage
- Amoxicillin-Clavulanate (Augmentin)
- Adult Immediate Release: 875 mg orally every 12 hours
- Adult Extended Release: 2000 mg orally every 12 hours
- Child: 45 mg/kg/day (90 mg/kg if resistance suspected) divided every 12 hours up to adult dosing
- Cefpodoxime (Vantin)
- Adult (and age >=12 years): 400 mg orally every 12 hours
- Child (age <12 years): 10 mg/kg/day divided every 12 hours orally (up to 200 mg/dose)
- Cefuroxime (Ceftin)
- Adult: 500 mg orally every 12 hours
- Child: 20 to 30 mg/kg/day (up to 1000 mg/day) orally divided twice daily
- Cefprozil (Cefzil)
- Identical dosing to Cefuroxime
- Cefdinir (Omnicef)
- Adult: 300 mg orally twice daily
- Child: 14 mg/kg/day (up to 600 mg/day) divided every 12 to 24 hours
- Levofloxacin (Levaquin)
- Adult: 600 mg orally daily
- Child: 10 to 20 mg/kg divided once to twice daily orally
- Relative contraindication due to risk of Arthropathy in juvenile animals
- However, human studies have not found signficant Arthropathy in children
- Amoxicillin-Clavulanate (Augmentin)
- Antibiotic 2 (choose one): MRSA Coverage (per Sanford protocol)
- Sanford recommends starting with two agents, the second agent for added MRSA coverage

X. Complications
-
Orbital Cellulitis (from contigious extension)
- Uncommon (<10% of Orbital Cellulitis extends from Preseptal Cellulitis)
- Most Orbital Cellulitis is an extension from ethmoid or Maxillary Sinusitis
- Intracerebral extension of Preseptal Cellulitis is rare without Orbital Cellulitis extension
- Protective fibrous layer prevents extension
