Parinaud's oculoglandular syndrome (POS) is a medical condition characterized by a specific set of symptoms affecting the eye and nearby lymph nodes.
[citation needed] The syndrome manifests as granulomatous conjunctivitis in one eye, accompanied by swollen lymph nodes in front of the ear on the same side.
Granulomatous conjunctivitis refers to inflammation of the conjunctiva, the membrane that covers the white part of the eye, characterized by the presence of granulomas, small areas of inflammation due to tissue injury.
Patients with POS may experience a red, irritated, and painful eye, fever, a general lack of well-being, swelling of nearby lymph glands, and sometimes increased tearing.
