Abstract

  • Diffuse unilateral subacute neuroretinitis (DUSN) is caused by a subretinal live and mobile nematode.

  • Acute phase: Patients usually present with severe pain, decreased vision, vitritis/papillitis, and tracks of grayish-white lesions—and a live nematode.

  • Late phase: Arterial narrowing, optic atrophy, diffuse disruption of the retinal pigment epithelium (RPE), with severe visual loss
