Diffuse unilateral subacute neuroretinitis.

Oman J Ophthalmol 2019 Jan-Apr;12(1):59-61

Department of Retina, Aravind Eye Hospital, Puducherry, India.

Diffuse unilateral subacute neuroretinitis (DUSN) is a subacute outer retinal inflammation due to the presence of a subretinal worm. The worm is identifiable in only 30% of the cases. The identification of the worm and laser photocoagulation of the worm remains the mainstay of treatment. Read More

Department of Ophthalmology, Columbia University, Edward S. Harkness Eye Institute, NewYork-Presbyterian Hospital, New York, NY, USA.

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. Read More

Department of Ophthalmology and Visual sciences, University of Michigan, Ann Arbor, Michigan, USA. Electronic address:

Parasitic infections of the eyes are a major cause of ocular diseases across the globe. The causative agents range from simple organisms such as unicellular protozoans to complex metazoan helminths. The disease spectrum varies depending on the geographic location, prevailing hygiene, living and eating habits of the inhabitants, and the type of animals that surround them. Read More

Diffuse Unilateral Subacute Neuroretinitis From Raccoon Exposure Resistant to Laser Photocoagulation.

Ophthalmic Surg Lasers Imaging Retina 2016 07;47(7):686-90

Diffuse unilateral subacute neuroretinitis (DUSN) is an ocular disease caused by a subretinal nematode worm. The authors present a unique case of a 9-year-old girl with DUSN due to presumed Baylisascaris procyonis, given the size of the worm and previous raccoon exposure. The worm was located in the inner retina and treated with laser photocoagulation and albendazole. Read More

Clin Microbiol Rev 2016 Apr;29(2):375-99

Department of Comparative Pathobiology, Purdue University College of Veterinary Medicine, West Lafayette, Indiana, USA.

Baylisascaris procyonis, the raccoon roundworm, infects a wide range of vertebrate animals, including humans, in which it causes a particularly severe type of larva migrans. It is an important cause of severe neurologic disease (neural larva migrans [NLM]) but also causes ocular disease (OLM; diffuse unilateral subacute neuroretinitis [DUSN]), visceral larva migrans (VLM), and covert/asymptomatic infections. B. Read More

Baylisascaris larva migrans.

Handb Clin Neurol 2013 ;114:251-62

Department of Comparative Pathobiology, College of Veterinary Medicine, Purdue University, West Lafayette, IN, USA.

Baylisascaris procyonis is a roundworm of the raccoon found primarily in North America but also known to occur in other parts of the world including South America, Europe, and Japan. Migration of the larvae of this parasite is recognized as a cause of clinical neural larva migrans (NLM) in humans, primarily children. It is manifested as meningoencephalitis associated with marked eosinophilia of the cerebrospinal fluid and peripheral blood. Read More

Diffuse unilateral subacute neuroretinitis (DUSN) is a usually unilateral inflammatory disease characterized by an insidious, usually severe loss of peripheral and central vision. Clinical characteristics are manifested in early and late stages. Parasites of different sizes and several species of nematodes have been reported as the etiology of DUSN without conclusive evidence about the specific agent. Read More

*Department of Ophthalmology, Universidade Federal de São Paulo, São Paulo, Brazil †Department of Ophthalmology, Universidade de Campinas ‡Department of Ophthalmology, Hospital de Olhos Niterói, Niteroi, Brazil.

Purpose: To document the intraretinal migration of presumed toxocara larvae mimicking punctate inner choroidopathy, idiopathic choroidal neovascularization, and diffuse unilateral subacute neuroretinitis.

Baylisascaris procyonis in raccoons (Procyon lotor) from eastern Colorado, an area of undefined prevalence.

Vet Parasitol 2012 Apr 7;185(2-4):330-4. Epub 2011 Nov 7.

Colorado State University Veterinary Diagnostic Laboratory, Fort Collins, CO 80523, USA.

Baylisascaris procyonis is a zoonotic parasite that has been documented in raccoons throughout much of the United States; however, no published information on its occurrence is available for the transition zone from the Great Plains to the Rocky Mountains. Because this parasite can cause neural larva migrans and diffuse unilateral subacute neuroretinitis in humans (as well as other hosts), a more complete understanding of the distribution of this parasite seems warranted for public health reasons. The purpose of this study was to begin to fill in the gaps in our knowledge of the distribution of B. Read More

Our purpose is to report a case of diffuse unilateral subacute neuroretinitis (DUSN) in which an ophthalmoscopically visible worm was found and optical coherence tomography (OCT) scans allowed the precise localization of the parasite in the intraretinal layers. Our findings suggest that the parasite moves in the inner portions of the retina possibly explaining the severe degenerative neural changes that it causes. Read More

Parasitic infections may damage various ocular tissues, thereby causing visual dysfunction. In 1950, Wilder described the first case in which larval forms of nematodal intestinal roundworms (Ascaridoidea: Ascaris, Toxocara, Ancylostoma, Necator, and Strongyloides) were implicated as a cause of intraocular disease. This review focuses on two disorders associated with parasitic infections: ocular toxocariasis and diffuse unilateral subacute neuroretinitis. Read More

Trends Parasitol 2010 Apr 25;26(4):162-7. Epub 2010 Feb 25.

Department of Microbiology and Immunology, College of Veterinary Medicine, Cornell University, Campus Road, Ithaca, NY 14850, USA.

Dogs and cats are hosts to hookworms that may cause zoonotic disease, most notably, cutaneous larva migrans. Ancylostoma braziliense is most often implicated in dermatological lesions, and Ancylostoma caninum has been associated with eosinophilic enteritis and suggested as a possible cause of diffuse unilateral subacute neuroretinitis in humans. Other manifestations include eosinophilic pneumonitis, localized myositis, folliculitis, erythema multiforme, or ophthalmological manifestations. Read More

Baylisascaris Procyonis Induced Diffuse Unilateral Subacute Neuroretinitis in New York City.

J Neuroparasitology 2010 Jan;1

Division of Ophthalmology, Maimonides Medical Center, Brooklyn, NY, USA.

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. Read More

The white dot syndromes.

Compr Ophthalmol Update 2007 Jul-Aug;8(4):179-200; discussion 203-4

Vitreous-Retina-Macula Consultants of New York, New York, NY, USA.

The white dot syndromes are a heterogeneous group of rare inflammatory disorders affecting the retina, the retinal pigment epithelium, and the choroid. Not all of these diseases actually cause white dots, but they all have unique lesions in the fundus. We describe acute posterior multifocal placoid pigment epitheliopathy, serpiginous choroiditis, birdshot chorioretinopathy, multifocal choroiditis with panuveitis, diffuse subretinal fibrosis syndrome, punctate inner choroidopathy, multiple evanescent white dot syndrome, and diffuse unilateral subacute neuroretinitis as the white dot syndromes in this review.

Diffuse unilateral subacute neuroretinitis.

Int Ophthalmol 2008 Apr 19;28(2):127-9. Epub 2007 Jul 19.

Singapore National Eye Centre, 11, Third Hospital Avenue, Singapore 168751, Singapore.

Background: In patients with diffuse unilateral subacute neuroretinitis (DUSN), the presence and, therefore, clinical visualization of subretinal nematode makes the diagnosis obvious. However when located under the retinal pigment epithelium (RPE), diagnosis is presumptive and challenging. We report a case of presumed DUSN to illustrate this diagnostic dilemma and to highlight the clinical signs which suggest the diagnosis. Read More
