Bartonella presenting as branch retinal artery occlusion in a child.

Branch retinal artery occlusion (BRAO) is rare in children. Bartonella is a known cause of branch retinal artery occlusion in adults, but it is typically not considered in the differential diagnosis for pediatric BRAO. We present the case of a 12-year old boy with a BRAO caused by a Bartonella henselae infection. This is the youngest such case reported in the literature. Although rare, Bartonella infection may be an important and underrecognized cause of pediatric BRAO.
