Pediatric Bartonella henselae neuroretinitis masking co-infections

PURPOSE: Neuroretinitis (NR) is an inflammatory disorder that presents with painless vision loss due to optic disc edema, peripapillary detachment, and macular lipid exudation. We report the first two documented cases of co-infections of pediatric NR due to Bartonella henselae with HSV and Toxocara cati, respectively. OBSERVATIONS: A 10-year-old female with acute right-sided facial droop, right eye pain, and acute visual loss of the right eye is diagnosed with co-infection of Bartonella and HSV retinitis and is successfully treated with acyclovir, rifampin, and doxycycline. A 13-year-old female with progressive visual loss of the left eye is diagnosed with co-infection of Bartonella and ocular toxocariasis and is successfully treated with doxycycline, rifampin, prednisolone, and albendazole. CONCLUSIONS AND IMPORTANCE: Early recognition and multi-modal treatment is necessary to prevent delayed diagnosis and treat the underlying NR causes for optimal visual recovery.
