Which of the following is NOT a main etiology of Parinaud's Oculoglandular Syndrome?

• A. Cat scratch fever
• B. Tularemia
• C. Lyme disease
• D. Tuberculosis

Answer: (C)

Parinaud's Oculoglandular Syndrome presents as unilateral granulomatous conjunctivitis with ipsilateral regional lymphadenopathy. The classic infectious causes are Bartonella henselae from cat scratch disease, Francisella tularensis from tularemia, and Mycobacterium tuberculosis from tuberculosis. Lyme disease, caused by Borrelia burgdorferi, is not considered a main etiology for this syndrome; ocular Lyme can occur in disseminated infection but does not typically produce the granulomatous conjunctivitis with preauricular or regional lymphadenopathy that defines Parinaud's. So Lyme disease is not a primary contributor to this condition, whereas cat scratch disease, tularemia, and TB regularly present with the characteristic conjunctival granulomatous inflammation and lymphadenopathy.
