Optic disk edema with a macular star

A 13-year-old boy presented with acute loss of vision inhis right eye of 2weeks' duration. He had a high feverand was ill for several days, then improved but suffered recurrent episodes of sweating and a high fever. Ophthalmoscopy of the righ eye showed optic disk edema, mild vitreous cells, and minimal exudates in the macula. Bartonella henselae titers were positive. A diagnosis of optic disk edema with a macular star secondary to cat-scratch disease was made. The patient was treated with doxycycline and made a dramatic improvement to visual acuity of 20/30 with a minimal residual relative central scotoma. The optic disk edema and macular star resolved, and the patient was left with mild optic atrophy in the right eye.
