Diffuse unilateral subacute neuroretinitis (DUSN) secondary to
raccoon roundworm (Baylisascaris procyonis) infection has been
reported in rural and suburban areas of North America and Europe
with extant raccoon populations. Here, we present a case of
Baylisascaris-induced DUSN from the densely populated borough of
Brooklyn in New York City and alert urban ophthalmologists to
consider this etiology even in areas not typically thought to be
associated with endemic risk factors. Infected raccoons also occur
in urban settings, and urban patients may be exposed in surrounding
areas. Most patients with Baylisascaris ocular larva migrans-DUSN
will not have concomitant neurologic disease; this fact and larval
neurotropism are both misconceptions regarding this infection.
