PMID: 32313895 Atypical manifestation occurs in 5% of the cases and may include Parinaud’s oculoglandular syndrome (which comprises granulomatous nonsuppurative conjunctivitis with adjacent ipsilateral preauricular lymphadenopathy), neuroretinitis, encephalitis, osteomyelitis, endcarditis, hepatosplenic lesions, and fever of unknown origin.

PMID: [38941282] Parinaud oculoglandular syndrome (POGS) is a unilateral granulomatous palpebral conjunctivitis associated with preauricular, submandibular, and occasionally cervical lymphadenopathies. POGS must be distinguished from Parinaud syndrome, the multicausal triad of impaired upward gaze, convergence retraction nystagmus, and pupillary hyporeflexia. Both syndromes were first reported by Henri Parinaud, a French ophthalmologist (3 cases of POGS in 1889). Several infectious diseases can cause POGS, usually with a conjunctival entry. The characteristic painful or tender lymphadenopathy initially appears in the primary regional lymph node regions of the eyelids. The most common background pathology is cat scratch disease (CSD) caused by Bartonella henselae.

PMID: 39286673 Henri Parinaud, an ophthalmologist from France first described the oculoglandular syndrome in 1889, which has come to be known as the ocular bartonellosis, describing three patients with fever, regional lymphadenopathy (preauricular and submandibular lymph nodes), and a follicular conjunctivitis.
