Think about cats in acute vision loss.

Cat-scratch disease (CSD) is a systemic illness caused by the gram-negative bacteria Bartonella henselae (B. henselae). Cats serve as the primary host reservoir for B. henselae, with cat fleas as the horizontal vector of transmission. It is transmitted to humans through close contact with cats and cat scratches and bites. We describe two cases of bilateral Bartonella neuroretinitis that were presented to Palmerston North Hospital Eye Clinic.
