Periorbital Cellulitis: Causes, Symptoms, and Treatment
Medically reviewed by Harsha Moole, MD, Internal Medicine. Last reviewed: October 23, 2026.
What kind of doctor treats Periorbital Cellulitis?
An ophthalmologist, a doctor who treats eye disease, usually treats periorbital cellulitis. A primary care doctor or pediatrician often helps. An otolaryngologist, an ear, nose, and throat doctor, may help if a sinus infection is involved. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is periorbital cellulitis?
Periorbital cellulitis is an infection of the eyelid or skin around the eye. It is also called preseptal cellulitis. The infection sits in the tissues in front of the orbital septum. This is a band of tissue that divides the eye socket into a front part and a back part.
Periorbital cellulitis is different from orbital cellulitis. Orbital cellulitis is an infection of the fat and muscles around the eye. It is a dangerous infection that can cause lasting problems and deeper infections.
Symptoms
Common signs include:
- Redness around the eye or in the white part of the eye.
- Swelling of the eyelid, the whites of the eyes, and the area around them.
- Warmth of the eyelid.
- A general feeling of being unwell and a low-grade fever.
This condition usually does not affect vision or cause eye pain. The redness can spread to the cheek and forehead. An abscess, a pocket of pus, in the eyelid is also common. Lower vision and pain when the eye moves point to the deeper orbital cellulitis instead.
Causes and who gets it
Periorbital cellulitis can occur at any age, but it more commonly affects children younger than 5 years old.
Most cases are caused by bacteria. Staphylococcus and Streptococcus are the most common types. Germs can get in through:
- A scratch, an injury, or a bug bite around the eye.
- A nearby infection, most often in the sinuses.
- The blood, from an upper respiratory infection or a middle ear infection.
Before a vaccine against Haemophilus influenzae type b was widely used, this germ often caused the infection, especially in children under 5. It is still common in people who have not had the vaccine.
How doctors diagnose it
Your provider will examine the eye, especially eye movements, and test your vision. You will also be asked about your symptoms.
Tests that may be ordered include a blood culture, a complete blood count (CBC), a CT scan, or an MRI scan. A CT scan can help when the eyelid is too swollen for a good eye exam. Cultures help doctors choose the best antibiotic.
Treatment
Antibiotics are given by mouth, by shots, or through a vein to help fight the infection. A mild case without fever can be treated as an outpatient, meaning outside the hospital. This uses antibiotics by mouth and daily visits to check progress.
Some people need to go to the hospital. This is true if antibiotics by mouth do not work in 48 hours. It is also true if the infection may have reached the eye socket. Then a CT scan is done and antibiotics are given through a vein. Children under 2 years old and patients with a fever and a severe infection are usually treated this way too.
An eyelid abscess may need to be cut open and drained. A team often treats this condition, including an ophthalmologist, a pediatrician or primary care doctor, and an ear, nose, and throat doctor if a sinus infection is involved.
Periorbital cellulitis almost always improves with treatment. In rare cases, the infection spreads into the eye socket and causes orbital cellulitis. Other problems can develop even with quick treatment. These include an abscess in the eye socket and meningitis, an infection of the lining around the brain.
When to see a doctor
Contact your provider right away if:
- The eye becomes red or swollen.
- Symptoms get worse after treatment.
- Fever develops along with eye symptoms.
Call 911 or go to the emergency room right away if it is painful or hard to move the eye, the eye looks like it is bulging out, or your vision gets worse. These can be signs of orbital cellulitis, which is a medical emergency. Also call 911 if you have trouble breathing, faint, or have a sudden change in mental state, such as confusion or being hard to wake.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either can look at the area around the eye, help decide if you need an eye doctor, and coordinate your follow-up care.
Common questions
Is periorbital cellulitis the same as preseptal cellulitis?
Yes, preseptal cellulitis is another name for periorbital cellulitis. Both names describe an infection of the eyelid or the skin around the eye.
Is periorbital cellulitis the same as orbital cellulitis?
No, they are different infections. Periorbital cellulitis affects the eyelid and skin around the eye. Orbital cellulitis affects the fat and muscles around the eye and is more dangerous.
Does periorbital cellulitis get better with treatment?
Yes, it almost always improves with treatment. In rare cases, the infection spreads into the eye socket and causes orbital cellulitis.
Who gets periorbital cellulitis?
It can happen at any age, but it is more common in children younger than 5 years old. A scratch, injury, or bug bite near the eye can let germs in.
