Cat scratch disease of the eye: a case report and literature review.

This is the case of a middle-aged male with no other medical issues who presented with acute, unilateral visual disturbance. In lieu of specific ophthalmologic findings, his age and presentation, he was treated for presumed inflammatory process. It was only after steroids and the results of serological testing that an infectious agent was determined. He was eventually diagnosed with ocular Bartonellosis. He was treated with oral doxycycline and rifampin and slowly improved. The thesis of this case report is that a thorough history prior to rapid and somewhat presumptive treatment may have prevented unnecessary immunosuppression and delay in appropriate antimicrobial therapy.
