Symptoms:

• 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)

Signs and tests:

An examination shows a red, tender, inflamed eye with possible ulcers in the cornea (surface). Tender lymph nodes may be present in front of the ear. You may have a fever and other signs of illness.

Blood tests will be done to check for infection. A white blood cell count may be high or low, depending on the cause of the infection.

Blood tests to check antibody levels are the main methods used to diagnose many of the infections that cause Parinaud syndrom. Other tests may include a biopsy of the lymph node and laboratory culture of eye secretions, lymph node tissue, or blood.
