Infectious Retinal and Choroidal Inflammation
Cat-scratch disease is associated with 2 ocular syndromes: (1) Parinaud oculoglandular syndrome, which consists of conjunctival inflammation with preauricular adenopathy, and (2) Leber stellate neuroretinitis, which includes macular star formation and optic nerve head swelling, often associated with a peripapillary serous macular detachment (Fig 11-21). Small, focal areas of retinitis or chorioretinitis occur frequently in patients with neuroretinitis. In rare cases, an optic nerve head angiomatous lesion can develop. Immunocompetent adults with cat-scratch disease are treated with doxycycline, 100 mg twice daily for 4–6 weeks. Oral erythromycin can be used in children. Prolonged treatment with doxycycline and rifampin can be used in immunocompromised adults or in patients with persistent infection.
