RESUMO
Purpose: cat-scratch disease is a bacterial infection transmitted from the scratch bite of a cat with Bartonella henselae. Ophtalmologic manifestations usually consist in manifest neuroretinitis defined by abrupt, unilateral, painless visual loss associated with stellate macular exudates and optic disc edema
Observation: We present a 14-Year old girl who manifested symptoms of decreased vision at the left eye associated to mild fever, diffuse myalgia and headache. Visual acuities were 9/10 at the right eye and 1/ 10 at the left one. Anterior segment evaluation was unremarkable. Fundus examination showed signs of neuroretinitis confirmed by fluorescein angiography. Visual field and color testing were contributive. History investigation found recent cat bites. Blood cultures Were obtained and Bartonella-henselae antibody titers were measured. Tuberculosis, toxoplasmosis, syphilis, rickettsiosis were excluded. Patient received oral doxycycline 100 mg and rifampicin 300 mg twice daily for 4 weeks. Evolution was marked by a promote resolution of neuroretinitis with a mildly decreased visual acuity
Discussion and Conclusion: Mutiple infectious disease should be evocated in case of neuroretinitis. Cat-scratch disease should be investigated
RESUMO
We report a single case of Susac's syndrome wich is a microangiopathy of the brain, retina and cochlea. A 45 years old women developed central retinal artery occlusion in the left eye, associated with bilateral hearing loss that mostly involved low and middle frequencies. MRI of the brain revealed numerous under-cortical, paraventricular and callous lesions. The treatment consisted of anticoagulation and antiplatelet drugs
