In simple words: Oculoglandular listeriosis is an eye and lymph node infection caused by bacteria found in contaminated food.Symptoms include red, painful eyes with discharge, swollen lymph nodes near the ears and neck, and possible eye muscle swelling or paralysis. It's diagnosed through symptoms, exposure history, physical exam, and blood tests. Treatment involves antibiotics.

Oculoglandular listeriosis, an infection that affects the eyes and lymph nodes, is caused by the bacterium Listeria monocytogenes, typically ingested with contaminated food.

Example 1: A patient presents with red, painful eyes, discharge, and swollen lymph nodes in the neck after consuming contaminated deli meat.A blood test confirms Listeria monocytogenes, leading to a diagnosis of oculoglandular listeriosis., A pregnant woman experiences mild flu-like symptoms and later develops eye inflammation and swollen lymph nodes.Testing reveals Listeria monocytogenes, but due to her pregnancy, her presentation is considered atypical oculoglandular listeriosis. , An immunocompromised individual develops severe eye pain, swelling, and vision changes after eating contaminated soft cheese.Oculoglandular listeriosis is diagnosed, requiring aggressive antibiotic treatment due to the patient's weakened immune system.

Symptoms (eye redness, pain, discharge, swollen lymph nodes), exposure history (consumption of potentially contaminated food), physical exam findings, and laboratory results confirming Listeria monocytogenes.
