Diffuse Unilateral Subacute Neuroretinitis with Typical Serpiginous Retinal Pigment Epithelial Atrophy

Abstract

We report a case of diffuse unilateral subacute neuroretinitis (DUSN) with atrophy of the serpiginous retinal pigment epithelium (RPE) which has not yet been reported in the Korean medical literature. A 41-year-old man complained a progressive visual loss and ocular pain in the left eye. The patient has a history of exposure to live doe’s bloods. On the slit lamp microscopy, a mild severity of inflammatory cells was observed in the vitreous cavity. Ophthalmoscopy showed the cluster of gray-white RPE atrophy, many tortuous serpiginous tract with sparing of the macular region in the left eye. Although the location of the nematode could not be identified, the appearance of serpiginous tract atrophy on subRPE and a history of exposure to live animal supported the diagnosis of DUSN.
