[Abrupt visual loss in children. Three case studies of ocular bartonellosis]

Abstract

Purpose: To evaluate the severity and progression of neuroretinitis in children caused by Bartonella.

Patients and methods: Retrospective study of three consecutive cases. Patients underwent ophthalmological, medical, and radiological evaluations. Bartonella serology was positive. Intravenous treatment was started immediately with antibiotics and steroids. Patients were re-evaluated after visual acuity recovery.

Results: Progression was quickly positive with fosfomycin and fluoroquinolones in all cases.

Conclusion: Bartonella induces neuroretinitis even without systemic signs of cat-scratch disease, with sometimes sudden bilateral blindness. Long-term progression is good but urgent medical treatment is necessary.
