Parinaud's Oculoglandular Syndrome is true for which statement?

• A. It is caused by Bartonella henselae infection
• B. It is commonly bilateral
• C. It does not involve lymph nodes
• D. It is primarily a corneal disease

Answer: (A)

Parinaud's Oculoglandular Syndrome centers on a granulomatous conjunctivitis with ipsilateral lymphadenopathy linked to Bartonella henselae infection, the same bacterium behind cat scratch disease. That connection makes the statement true: Bartonella henselae causes this syndrome, typically after cat exposure.

The other ideas don’t fit the picture: the condition is usually unilateral, not commonly bilateral. Lymph node involvement is a defining feature, so saying there are no involved lymph nodes is incorrect. And while conjunctival inflammation is primary, it is not described as mainly a corneal disease; corneal involvement, if it occurs, is not the hallmark.

So, Bartonella henselae is the correct association for Parinaud's Oculoglandular Syndrome.
