VALVERDE-GUBIANAS, M. et al. Neuroretinitis: Clinical cases. Arch Soc Esp Oftalmol [online]. 2009, vol.84, n.8, pp.389-394. ISSN 0365-6691.

Objective: Evaluate the etiology and the most frequent funduscopic alterations of the neuroretinitis. Methods: We present the case of a woman 24 years old with a bilateral decrease of visual sharpness (AV), painless and progressive, the funduscopic examination of which reveals a bilateral optical disc edema, with no hemorrhages or exudates, retina edema of the posterior pole and phlebitic areas. The systematic study was normal except for the hemogram (18,000/mm³ leucocytes with 79% neutrophils) and the positive serology next to a Chlamydia. We also present the case of a 64 years old woman with a decrease of AV at the right eye of one week duration. At the back of the eye a macular star can be seen, and papilla edema. A systematic study gave normal results and positive serology at Bartonella henselae. Results: The illness produced by a cat scratch is the most common cause of neuroretinitis. The customary findings are a loss of AV, discromatopsia, afferent papillary defects and abnormality on the visual field. Other frequent findings at the back of the eye are hemorrhagic nerve fibers, cotton-like exudates, papilla edema, macular star and glassy inflammation. The roll of antibiotic therapy is questionable. Oral ciprofloxacine seems to give good results.
