What kind of doctor treats Orbital Cellulitis?
An ophthalmologist, an eye doctor, usually leads care for orbital cellulitis. Care often also involves an ENT doctor (ear, nose, and throat), a children's doctor, and an infection specialist. 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 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. It is different from periorbital cellulitis, which is an infection of the eyelid or skin around the eye.
Symptoms
Symptoms may include:
- Painful swelling of the upper and lower eyelid, and possibly the eyebrow and cheek.
- Bulging eyes.
- Decreased vision.
- Pain when moving the eye.
- Trouble moving the eye.
- Double vision.
- A shiny, red or purple eyelid.
- A general ill feeling.
- Fever, which may or may not be present.
- A headache or a runny nose.
In children, the infection may get worse very quickly. It can lead to visual difficulties or blindness.
Causes and who gets it
Most often, a bacterial infection spreads from the sinuses into the eye socket. In children, it often starts out as a sinus infection. It can also happen when an infection spreads into the eye socket. The infection may start in the eyelid skin, a nearby area, or the bloodstream. Infections of the teeth can spread this way too. An injury, an object in the area, or surgery can also be a cause.
Risk factors include a recent upper respiratory illness, a sinus infection, or an injury. An infection in or around the eye is also a risk. So is an infection elsewhere in the body. The infection used to be more common in young children, under the age of 7. A vaccine that helps prevent this infection has made it rare.
How doctors diagnose it
Doctors mainly diagnose it by examining the patient. Common tests include a complete blood count (CBC) and a blood culture. Doctors may also order an X-ray of the sinuses and surrounding area. They may also order a CT scan or MRI of the sinuses and orbit (eye socket). A CT scan is the imaging test of choice for orbital cellulitis. Doctors may also test fluid from the eye and nose, or swab the throat. Children who are very sick may also have a spinal tap.
Treatment
In most cases, a hospital stay is needed. Treatment most often includes antibiotics given through a vein (IV). Doctors may change the antibiotic based on test results. Steroids given through a vein may also help children.
Surgery may be needed if there is an abscess. It may also be needed to relieve pressure in the space around the eye. The infection can get worse very quickly, so a person with this condition must be checked every few hours. Care usually takes a team of children's doctors, ENT surgeons, eye doctors, and infection specialists. With prompt treatment, a person can recover fully.
When to see a doctor
Orbital cellulitis is a medical emergency that needs to be treated right away. Go to the emergency room right away if you have eyelid swelling, especially with a fever, or a bulging eye, vision loss, double vision, or pain or trouble moving the eye. Call 911 if you have confusion, fainting, or trouble breathing. Problems that can follow include meningitis and vision loss.
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. After a hospital stay, a direct primary care doctor can handle follow-up visits and help coordinate care with specialists.
Common questions
Is orbital cellulitis an emergency?
Yes, orbital cellulitis is a medical emergency that needs to be treated right away. In most cases, a hospital stay is needed.
What is the difference between orbital and periorbital cellulitis?

Can orbital cellulitis cause vision loss?
Yes, it can. Orbital cellulitis infections in children may get worse very quickly and lead to visual difficulties or blindness. With prompt treatment, a person can recover fully.
Can orbital cellulitis be prevented?
It may be possible to lower the risk. Getting scheduled HiB vaccine shots will prevent the infection in most children. Prompt treatment of a sinus or dental infection may prevent it from spreading and becoming orbital cellulitis.
