Cat Scratch Disease Presenting with Right Branch Retinal Artery Occlusion and Left Neuroretinitis.

Introduction: Bartonella henselae , the causative agent of cat scratch disease (CSD), presents with diverse ocular manifestations, posing diagnostic challenges. This study aimed to elucidate the diagnostic complexities through a unique case.
Case Presentation: A 42-year-old male presented with vision loss in the right eye, subsequent to flu-like symptoms following exposure to a stray kitten. Clinical examination revealed branch retinal artery occlusion (BRAO) in the right eye and neuroretinitis in the left, indicating concurrent ocular manifestations of CSD. Thorough investigations, including serological testing, ruled out alternative causes, highlighting the rarity of such coexisting ocular complications.
Conclusions: The coexistence of BRAO and neuroretinitis in different eyes underscores the variable presentation of CSD. Recognition of infectious etiologies, particularly Bartonella , is paramount in diagnosing ocular vasculopathies. This case emphasizes the importance of considering Bartonella infection in patients with ocular vascular occlusions, especially in the context of recent cat exposure and systemic symptoms suggestive of CSD.
