Abstract

Diffuse unilateral subacute neuroretinitis (DUSN) is a rare, sight-threatening inflammatory condition caused by a nematode. It typically affects healthy children and young adults. Various nematodes have been implicated, including those that originate from dogs and raccoons. Late stage findings include optic nerve atrophy, retinal arterial attenuation, “retinitis pigmentosa-like” retinal pigmentary changes, and central and peripheral vision loss. We present a case study of long-standing DUSN. The combination of optical coherence tomography (OCT) and visual electrophysiology testing proved invaluable in establishing a presumptive diagnosis of this rare condition.
