Parinaud Oculoglandular Syndrome: Causes, Symptoms, and Treatment

What kind of doctor treats Parinaud Oculoglandular Syndrome?
An ophthalmologist, an eye doctor, usually treats Parinaud oculoglandular syndrome. An infectious disease doctor, who treats infections, may also help find the cause. 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 Parinaud oculoglandular syndrome?
Parinaud oculoglandular syndrome is an eye problem that is similar to conjunctivitis, or pink eye. It most often affects only one eye. It comes with swollen lymph nodes, which are small glands that help fight infection, and an illness with a fever.
The outlook in most cases is excellent.
Do not mix it up with Parinaud syndrome. That is a different disorder in which you have trouble looking upward. It can be caused by a brain tumor and needs a very prompt check by a health care provider.
Symptoms
Symptoms can include:
- A red, irritated, painful eye that looks like pink eye.
- Fever and a general ill feeling.
- More tearing than usual.
- Swollen lymph glands, often in front of the ear.
- Eye discharge and mild puffiness around the eye.
The eye may also have small growths, called nodules, on the inside of the eyelid or the white of the eye. These can sometimes form sores during healing. Serious complications are rare. The infection can spread to nearby tissues or into the bloodstream.
Causes and who gets it
An infection causes this syndrome. The germ can be a bacterium, a virus, a fungus, or a parasite. The most common causes are cat scratch disease and tularemia, also called rabbit fever. Cat scratch disease is caused by a bacterium called Bartonella henselae. Less common causes include tuberculosis and syphilis.
Germs can enter the eye on a finger or other object. Tiny air droplets that carry the germs can also land on the eye. With cat scratch disease, a history of cat contact is often present, but a bite or scratch may not be obvious. More cases are reported among children and veterinary workers.
People with tularemia are typically hunters, campers, or meat handlers. You can lower your risk by washing your hands often and avoiding cat scratches, even from a healthy cat. Avoid contact with wild rabbits, squirrels, and ticks.
How doctors diagnose it
A doctor will examine your eye and ask about recent contact with cats, dogs, fleas, or other animals. You may also be asked about travel and outdoor activities. The exam may show a red, tender eye and tender lymph nodes in front of the ear.
Blood tests check for infection. A blood test for antibody levels, which are signs your body is fighting a germ, is the main way to diagnose many of these infections. Other tests may include a lymph node biopsy, which means taking a small piece of tissue to study. Doctors may also grow germs from eye fluids, lymph node tissue, or blood. A test called PCR, which looks for a germ's genetic material, may also be used.
Treatment
Treatment depends on the cause. Antibiotics may help, and surgery may be needed in rare cases to clean away infected tissue. Cat scratch disease usually clears on its own, so treatment is often supportive. Eye drops that fight many kinds of germs may be used to prevent a second infection. Antibiotics that work throughout the body are recommended for moderate to severe disease, which more commonly involves people with weak immune systems. Doctors may choose doxycycline, azithromycin, or ciprofloxacin, among other antibiotics. For severe tularemia, doctors use the antibiotics streptomycin or gentamicin.
A fungus called Sporothrix can also cause this syndrome. It is treated with antifungal medicines. If the diagnosis is made early and treatment starts right away, the outcome can be very good.
When to see a doctor
Contact your provider if you have a red, irritated, painful eye. Fever and swollen glands in front of the ear can come with it, so tell your provider about them.
See a provider right away if you have trouble looking upward. This is a sign of a different disorder, Parinaud syndrome, and it needs a very prompt check.
Call 911 or go to the emergency room if you have a sudden change in vision, trouble breathing, a change in mental state such as confusion, or fainting.
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 kind of doctor can look at a red, painful eye, ask about animal contact, and order first blood tests. They can also refer you to an eye doctor and follow up after treatment.
Common questions
Is Parinaud oculoglandular syndrome the same as Parinaud syndrome?
No, they are different disorders. Parinaud oculoglandular syndrome is a pink eye-like infection with swollen glands. Parinaud syndrome, also called upgaze paresis, is trouble looking upward.
What causes Parinaud oculoglandular syndrome?
An infection causes it. The most common causes are cat scratch disease and tularemia, also called rabbit fever.
Is Parinaud oculoglandular syndrome serious?
Serious complications are rare. The outlook depends on the cause, and it can be very good with early treatment.
Can Parinaud oculoglandular syndrome be prevented?
Yes, you can lower the chance of getting it. Frequent hand washing helps. Avoid being scratched by a cat, even a healthy cat, and avoid contact with wild rabbits, squirrels, and ticks.
