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.
继发于浣熊蛔虫（拜氏狸殖吸虫）感染的弥漫性单侧亚急性神经视网膜炎（DUSN）已在北美和欧洲有现存浣熊种群的农村和郊区被报道。在此，我们报告一例来自纽约市人口密集的布鲁克林区由拜氏狸殖吸虫引起的DUSN病例，并提醒城市眼科医生即使在通常不被认为与地方流行危险因素相关的地区也要考虑这种病因。受感染的浣熊也出现在城市环境中，城市患者可能在周边地区接触到感染源。大多数患有拜氏狸殖吸虫眼幼虫移行症 - DUSN的患者不会伴有神经系统疾病；这一事实以及幼虫的嗜神经性都是关于这种感染的误解。
