[Unilateral neuroretinitis revealing cat-scratch disease]. / Neurorétinite unilatérale révélant une maladie des griffes du chat.

We report a case of cat-scratch disease neuroretinitis. A 26-year-old man was referred for severe right visual loss. Posterior segment examination showed a papilledema with macular edema. Bartonella henselae immunoglobulin G testing was positive. Four weeks of antibiotic therapy combining oral ciprofloxacin and doxycycline led to progressive resolution of the neuroretinitis and improvement in visual acuity. This report reminds that B. henselae infection can be the cause of neuroretinitis. Its prognosis can be improved by early treatment.
