To report a case of solitary idiopathic choroiditis associated with choroidal neovascularization.Case report of a 36-year-old healthy man who was referred for floaters in the left eye of 3 weeks' duration.Fundus examination of the left eye revealed a yellow-white subretinal lesion superior to the fovea. It was associated with a small subretinal hemorrhage and a macular detachment, which extended into the fovea. No vitreous cells were detected. The right eye was normal. The visual acuity was 20/20 in the right eye and 20/50 in the left eye. Laboratory evaluation for inflammatory or infectious diseases was nonrevealing. Fluorescein angiography showed Type 2 or so-called classic choroidal neovascularization associated with retinochoroidal anastomoses. After two laser treatments with poor outcomes, the lesion was effectively treated with oral steroids. A reactivation occurred 1.5 years later, and it was also successfully treated with oral steroids.Solitary idiopathic choroiditis can rarely be associated with choroidal neovascularization. Oral steroid treatment seems to be the preferred form of therapy rather than some form of interventional modality.
