Bartonella henselae infection associated with peripapillary angioma, branch retinal artery occlusion, and severe vision loss.

Purpose: To report atypical clinical features of Bartonella henselae neuroretinitis treated with combination antibiotics.
Method: Case report.
Results: A 20-year-old man with a positive B. henselae titer developed a unilateral neuroretinitis, a large peripapillary angiomatous lesion, branch artery occlusion with ischemic maculopathy, and vision loss that failed to improve with clindamycin. Treatment with doxycycline and rifampin led to rapid clinical improvement. The severe vision loss in this case is atypical.
Conclusions: Ocular findings associated with B. henselae infection may include retinal angiomatous lesion and branch retinal artery occlusion. Doxycycline and rifampin were successful in treating the infection.
