Parinaud oculoglandular syndrome
Cat scratch disease; Oculoglandular syndromeParinaud oculoglandular syndrome is an eye problem that is similar to conjunctivitis ("pink eye"). It most often affects only one eye. It occurs with swollen lymph nodes and an illness with a fever.
Swollen lymph nodes
Lymph nodes are present throughout your body. They are an important part of your immune system. Lymph nodes help your body recognize and fight germ...

Causes
Parinaud oculoglandular syndrome (POS) is caused by an infection with bacteria, a virus, fungus, or parasite.
The most common causes are cat scratch disease and tularemia (rabbit fever). The bacteria that cause either condition can infect the eye. The bacteria can directly enter the eye (on a finger or other object), or air droplets that carry the bacteria can land on the eye.
Tularemia
Tularemia is a bacterial infection in wild rodents. The bacteria are passed to humans through contact with tissue from the infected animal. The bac...

Symptoms
Symptoms include:
- Red, irritated, and painful eye (looks like "pink eye")
- Fever
- General ill feeling
- Increased tearing (possible)
- Swelling of nearby lymph glands (often in front of the ear)
Exams and Tests
An exam shows:
- Fever and other signs of illness
- Red, tender, inflamed eye
- Tender lymph nodes may be present in front of the ear
- There may be growths (conjunctival nodules) on the inside of the eyelid or the white of the eye
Blood tests will be done to check for infection. The white blood cell count may be high or low, depending on the cause of the infection.
White blood cell
A WBC count is a blood test to measure the number of white blood cells (WBCs) in the blood. It is a part of a complete blood count (CBC). WBCs are a...

- Biopsy of the lymph node
Biopsy of the lymph node
A lymph node biopsy is the removal of lymph node tissue for examination under a microscope. The lymph nodes are small glands that make white blood ce...

Treatment
Depending on the cause of the infection, antibiotics may be helpful. Surgery may be needed in rare cases to clean away the infected tissues.
Outlook (Prognosis)
The outlook depends on the cause of the infection. In general, if the diagnosis is made early and treatment starts right away, the outcome of POS can be very good.
Possible Complications
Serious complications are rare.
The conjunctival nodules can sometimes form sores (ulcers) during the healing process. The infection can spread to nearby tissues or into the bloodstream.
When to Contact a Medical Professional
You should contact your provider if you develop a red, irritated, painful eye.
Prevention
Frequent hand washing can reduce the likelihood of getting POS. Avoid being scratched by a cat, even a healthy cat. You can avoid tularemia by not having contact with wild rabbits, squirrels, or ticks.

Lymph nodes play an important part in the body's defense against infection. Swelling might occur even if the infection is trivial or not apparent. Swelling of lymph nodes generally results from localized or systemic infection, abscess formation, or malignancy.
