title: [Cat-scratch disease neuroretinitis].
abstract: We report a case of cat-scratch disease neuroretinitis for which systemic and ocular investigations proved the responsibility of Bartonella henselae. An 11-year-old boy was referred to the hospital in November 2002 for severe visual loss in the left eye over the preceding 2 weeks. At the same time, he also developed a flu-like illness. The best corrected acuity in the left eye was counting fingers at 30 cm. Posterior segment examination on the left eye showed an optic disk edema with papillary and peripapillary hemorrhages and serous retinal detachment, mild vitreous inflammation, and two little perivascular white spots. The medical history was unremarkable except for a cat scratch on his left forearm 2 months before. Four weeks of antibiotic therapy including oral rifampin and doxycycline was used. Bartonella henselae immunoglobulin M were first detected with Bartonella henselae immunoglobulin G testing negative at this time. A 3-week serum showed immunoglobulin M seroreversion, while Bartonella henselae immunoglobulin G appeared. Other causes of optic disk edema with macular star were excluded by biological data. Bartonella antibodies to both Bartonella henselae and Bartonella clarridgeiae were detected in the cat. Ophthalmic follow-up showed progressive resorption of the neuroretinitis and the visual acuity increased to 5/10. The significance of this case report lies in the reminder that this pathology can be the cause of neuroretinitis; the prognosis can be improved by earlier treatment.
