Orbital Cellulitis: What You Need to Know
What Is Orbital Cellulitis?
Orbital cellulitis is an infection that develops deep within the eye socket, affecting the fat and muscles around the eyeball. The condition is considered a medical emergency, as it can threaten both vision and health if not treated quickly.
Most often, orbital cellulitis is caused by bacteria spreading from a sinus infection, especially the ethmoid sinuses near the nose. Other sources include skin infections around the eye after a scratch, insect bite, or trauma, and rarely, dental infections or bloodstream infections.
This condition is more common in children, usually ages 7 to 12, but adults can be affected as well. People with chronic sinus infections, weakened immune systems, or uncontrolled diabetes are at higher risk for orbital cellulitis.
Unlike common eye infections like conjunctivitis (pink eye), orbital cellulitis affects the deeper tissues behind the eye and can progress rapidly. It is more serious than periorbital (preseptal) cellulitis, which only involves the eyelid and surrounding skin and not the tissues inside the orbit.
Recognizing Symptoms
Knowing the symptoms of orbital cellulitis can help you seek immediate treatment and lower your risk of serious complications. Symptoms usually develop suddenly and worsen quickly.
Orbital cellulitis often causes severe swelling and redness of the eyelids and the area around the eye. The eye may bulge forward (proptosis), and it can be painful, especially when moving the eye.
Other symptoms that may develop include:
- Blurry or double vision, or vision loss
- Fever or chills
- Pain in the cheek or forehead, often near the sinuses
- Restricted eye movement or trouble opening the eye
- Headache, fatigue, or a general feeling of being unwell
If you or your child have swelling that spreads quickly, severe pain, vision changes, high fever, confusion, or stiffness in the neck, get emergency care right away. Orbital cellulitis can lead to serious complications, including infections of the brain or loss of vision, if not recognized and treated in time.
How Is Orbital Cellulitis Diagnosed and Treated?
At ReFocus Eye Health Penndel, our ophthalmologists use a combination of advanced exams and imaging to diagnose orbital cellulitis and guide your treatment. Fast, expert care greatly improves outcomes for both children and adults in Penndel, Levittown, Bensalem, Bristol, and nearby communities.
Your eye doctor will start with a thorough eye and facial exam and ask about your recent symptoms, illnesses, and injuries. Blood tests may also be ordered to check for infection, along with imaging to see inside the orbit.
A CT scan is the most common imaging test for orbital cellulitis. It provides a clear view of the bones, tissues, and sinuses around the eye. In certain cases, an MRI may be recommended, especially for children or when there is concern about infection spreading to the brain or nearby tissues.
Most people with orbital cellulitis will require a hospital stay for intravenous (IV) antibiotics, which work quickly to stop the infection. Hospital care also allows for close observation and rapid response if the infection worsens or does not improve as expected.
Surgery may be needed if an abscess (a pocket of pus) forms behind the eye, if vision is threatened, or if the infection does not respond to antibiotics. The procedure usually involves draining the abscess to relieve pressure and prevent long-term complications.
Along with antibiotics or surgery, supportive treatments help you feel better and recover, including:
- Medications for pain and fever
- Fluids to prevent dehydration
- Careful monitoring of your vision and eye movements
- Sinus treatment if a sinus infection is the source
Prevention and Protecting Your Eye Health
While not all cases can be prevented, certain habits and medical care can help lower your risk of orbital cellulitis and related complications for you and your family.
Good hygiene and prompt care for infections are key. Try these tips:
- Wash your hands often and avoid touching your eyes
- Treat any cuts, bites, or scrapes near the eye right away
- Manage allergies and sinus congestion to reduce infection risk
- Wear protective eyewear during sports or outdoor projects
For patients with diabetes or immune system conditions, controlling these underlying issues with help from your medical team can lower your chances of severe infections like orbital cellulitis. Report sinus infections or facial pain promptly to your doctor.
Frequently Asked Questions
Below are answers to common questions our patients in the Greater Philadelphia Metropolitan Area have about orbital cellulitis and your care at ReFocus Eye Health Penndel.
No. Pink eye (conjunctivitis) affects the surface of the eye and is usually mild. Orbital cellulitis is a deeper, more dangerous infection inside the eye socket and always needs urgent medical treatment.
If treated quickly, most patients recover their vision completely. However, delay in treatment can lead to severe damage, including blindness, so prompt care is critical.
Yes, children between ages 7 and 12 are at higher risk, but adults can also develop the condition, especially if they have sinus infections or immune problems.
Most people start to improve within 1 to 2 days of starting IV antibiotics, but full recovery can take one to two weeks. Complete your entire treatment and attend all follow-up visits with your eye doctor.
Recurrence is uncommon if you finish your treatment and underlying causes like sinus infections are managed. Follow your doctor’s advice to stay healthy and lower your risk.
The infection inside the orbit is not contagious, but the bacteria that caused it, such as those from a sinus or skin infection, can sometimes spread to others. Practicing good hygiene helps prevent this.
