This 45-year-old male presented with blurry vision in his left eye and was referred to the University of Iowa for unilateral uveitis. A subretinal nematode was identified on exam next to a crop of yellow-white macular lesions. He was diagnosed with diffuse unilateral subacute neuroretinitis (DUSN), likely secondary to raccoon roundworm (Baylisascaris procyonis) as the patient was an avid outdoorsman and hunter. The nematode was killed by laser and the patient completed albendazole 400mg/day for 30 days. Included are photos demonstrating the nematode in two different locations and after laser treatment.
