Bartonella hanselae retinitis patient evaluated with multimodal retinal exams.

Abstract

BACKGROUND:

Cat scratch disease is a systemic infectious illness caused by the bacterium Bartonella henselae. The most common ophthalmological involvement due to infection by Bartonella is Parinaud oculoglandular syndrome, whereas the most common posterior segment findings are neuroretinitis and subsequent late macular star. Moreover, other findings, such as retinal or subretinal lesions, intermediate uveitis and angiomatous lesions, may be present.

CASE PRESENTATION:

A 37-year-old female patient with retinal findings and serological confirmation of Bartonella infection was evaluated via multimodal retinal exams. The patient received treatment with doxycycline 100 mg twice daily for 2 weeks. One month after treatment, complete improvement of her visual scotoma symptoms was confirmed. A swept-source optical coherence tomography exam also showed decreases in the size and intraretinal extension of the lesion. Improvement of light perception at the affected area was confirmed by microperimetry.

CONCLUSIONS:

Bartonella henselae infection, particularly retinitis, can present a variable spectrum of clinical and ophthalmological findings. Multimodal retinal exams can clearly identify lesion characteristics, thus providing important information for diagnosis and the evaluation of lesion improvement after antibiotic treatment.
