Periorbital Cellulitis: Causes, Symptoms and Diagnosis
Periorbital cellulitis is an infection of the eyelid or skin around the eyes, often caused by bacteria. This condition can lead to severe complications if not treated promptly and properly. In this article, we will delve deep into the causes, symptoms, diagnosis, and treatment options for periorbital cellulitis.
What is Periorbital Cellulitis?
Periorbital cellulitis, also known as preseptal cellulitis, is an infection that occurs in the soft tissues of the eyelid and periorbital area. Unlike orbital cellulitis, periorbital cellulitis does not involve the orbit and is generally less severe. However, prompt treatment is essential to prevent the infection from spreading to the orbit and causing complications.
Causes of Periorbital Cellulitis
Periorbital cellulitis is predominantly caused by bacterial infections. Common culprits include:
- Staphylococcus aureus: Including methicillin-resistant Staphylococcus aureus (MRSA).
- Streptococcus pneumoniae: Often associated with sinusitis.
- Haemophilus influenzae: Less common due to vaccination.
The infection can originate from local trauma, insect bites, or spread from adjacent structures like the sinuses. In children, it is frequently secondary to upper respiratory infections or sinusitis.
Risk Factors
Several factors can increase the risk of developing periorbital cellulitis:
- Age: More common in children under 5 years.
- Trauma: Cuts or abrasions around the eye.
- Sinusitis: Especially ethmoid sinusitis.
- Immunocompromised state: Conditions like diabetes or immunosuppressive therapy.

Get A Second OpinionSymptoms of Periorbital Cellulitis
Recognizing the symptoms of periorbital cellulitis is crucial for timely intervention. Common symptoms include:
- Redness and swelling: Around the eyelid and periorbital area.
- Pain: Localized pain that increases with touch.
- Fever: Often present, especially in children.
- Warmth: The affected area may feel warm to the touch.
- Reduced eye movements: Although this is more indicative of orbital cellulitis.
It's important to distinguish periorbital cellulitis from orbital cellulitis, which presents with more severe symptoms such as proptosis, ophthalmoplegia, and vision changes.
Diagnosis of Periorbital Cellulitis
Accurate diagnosis is essential for effective treatment. The diagnostic process typically involves:
Clinical Examination
A thorough clinical examination by a healthcare professional is the first step. This includes:
- Visual inspection: To assess redness, swelling, and warmth.
- Palpation: To evaluate pain and tenderness.
- Eye movement tests: To rule out orbital involvement.
Radiology
Radiological imaging plays a vital role in diagnosing periorbital cellulitis, especially when orbital involvement is suspected.
Computed Tomography (CT)
A CT scan of the orbits and sinuses can help differentiate between periorbital and orbital cellulitis. It provides detailed images of the soft tissues, bones, and any abscess formation.
Magnetic Resonance Imaging (MRI)
MRI is another imaging modality that offers superior soft tissue contrast. It is particularly useful in complex cases or when complications are suspected.
Laboratory Tests
Blood tests, including complete blood count (CBC) and blood cultures, can help identify the causative organism and assess the severity of the infection.
Treatment of Periorbital Cellulitis
Antibiotic Therapy
Antibiotics are the cornerstone of periorbital cellulitis treatment. The choice of antibiotic depends on the severity of the infection, the patient's age, and the presence of any underlying conditions.
Empirical Therapy
For mild to moderate cases, empirical therapy with oral antibiotics is often sufficient. Commonly prescribed antibiotics include:
- Amoxicillin-clavulanate
- Cefuroxime
- Clindamycin (especially if MRSA is suspected)
For severe cases or when the patient is immunocompromised, intravenous antibiotics may be necessary. Options include:
- Ceftriaxone
- Vancomycin (for MRSA coverage)
- Metronidazole (for anaerobic coverage)
Duration of Therapy
The typical duration of antibiotic therapy ranges from 7 to 10 days, but this may vary based on the patient's response to treatment and the severity of the infection.
Surgical Intervention
In rare cases, surgical intervention may be required, particularly if there is an abscess that needs drainage or if the infection does not respond to antibiotic therapy.
Supportive Care
Supportive care measures are also important in the management of periorbital cellulitis. These include:
- Pain management: Using analgesics such as acetaminophen or ibuprofen.
- Hydration: Ensuring adequate fluid intake.
- Monitoring: Regular follow-up to monitor the response to treatment and detect any complications early.

Book an AppointmentComplications of Periorbital Cellulitis
If left untreated or inadequately treated, periorbital cellulitis can lead to serious complications, such as:
- Orbital cellulitis: A more severe infection that can threaten vision.
- Abscess formation: In the eyelid or orbit.
- Cavernous sinus thrombosis: A rare but life-threatening condition.
- Meningitis: Infection spreading to the meninges.
Preventive Measures
Preventing periorbital cellulitis involves addressing the underlying risk factors and prompt treatment of any predisposing conditions.
Vaccination
Vaccination against Haemophilus influenzae type b (Hib) and Streptococcus pneumoniae can significantly reduce the incidence of periorbital cellulitis, especially in children.
Prompt Treatment of Sinusitis and Upper Respiratory Infections
Early and effective treatment of sinusitis and upper respiratory infections can prevent the spread of infection to the periorbital area.
Good Hygiene Practices
Maintaining good hygiene, especially around the eyes, can help prevent infections. This includes:
- Regular hand washing
- Avoiding touching or rubbing the eyes
- Proper care of any cuts or abrasions near the eyes
Frequently Asked Questions
1. What causes periorbital cellulitis?
Periorbital cellulitis is caused by bacteria entering the skin through cuts, insect bites, or sinus infections, often involving Staphylococcus or Streptococcus.
2. What are the symptoms of periorbital cellulitis?
Symptoms include swelling, redness, warmth, and tenderness around the eye, along with fever and sometimes vision changes.
3. How is periorbital cellulitis treated?
Treatment includes antibiotics, either oral or intravenous, depending on the severity of the infection.
4. How is periorbital cellulitis diagnosed?
Diagnosis involves physical examination, blood tests, and sometimes CT scans to rule out orbital cellulitis, which affects deeper tissues.
5. How is periorbital cellulitis treated in adults?
In adults, treatment typically involves oral antibiotics for mild cases, with hospitalization required for more severe infections.
