Widefield SS-OCTA for Localization of Retinal Nematode in Diffuse Unilateral Subacute Neuroretinitis.

Diffuse unilateral subacute neuroretinitis (DUSN) is a rare form of chorioretinitis caused by retinal infestation by nematode larvae. Definitive diagnosis requires visualization of a motile nematode, but this can be challenging because the nematode is small, translucent, and usually motionless with overlying media opacity from cellular inflammation. The authors describe a case of DUSN in which widefield swept-source optical coherence tomography angiography was used to localize a midperipheral intraretinal nematode facilitating subsequent clinical observation of movement.

Enface vitreous OCT 'worm holes': A novel finding in a patient with diffuse unilateral subacute neuroretinitis (DUSN).

Purpose: To describe a case of diffuse unilateral subacute neuroretinitis (DUSN), a rare condition that causes progressive vision loss following infection by a nematode using enface vitreous imaging.

Observations: We present the clinical findings of a 37-year-old female, clinically diagnosed with DUSN after a non-invasive multimodal imaging approach that included MultiColor scanning laser imaging and enface vitreous OCT, which revealed the nematode body and lacunae created by worm migration, respectively.

Conclusion And Importance: To our knowledge, this is the first reported case of lacunae visualized using enface vitreous optical coherence tomography (OCT), potentially marking the migration path of the nematode.

Presumed diffuse unilateral subacute neuroretinitis and cat-scratch disease: Dual infection in a single patient.

A healthy 35-year-old Malay woman presented with left eye pain for 1 week, and ocular examination showed evidence of panuveitis. She had granulomatous type of anterior uveitis with secondary high intraocular pressure (IOP). Fundus showed optic disc swelling, mild vitritis, and multiple subretinal lesions, which later formed a migratory track.

Short-term oral albendazole therapy for diffuse unilateral subacute neuroretinitis: A case report.

Purpose: To report on a case of diffuse unilateral subacute neuroretinitis (DUSN) that was successfully treated with a short course of oral albendazole.

Observations: A 51-year-old male presented with severe visual loss secondary to DUSN associated with a positive serology. Because the parasite could not be detected on fundoscopy, first-line treatment with photocoagulation could not be administered.

Surgical Removal of Intraocular Parasite in a Patient With Diffuse Unilateral Subacute Neuroretinitis.

Diffuse unilateral subacute neuroretinitis (DUSN) is a rare ocular infectious disease caused by migrating larvae of a nematode. DUSN is often a diagnostic challenge as it is difficult to identify the pathogenic nematode on funduscopic examination because it moves frequently and often resides within the subretinal space. Herein, the authors present a patient with unilateral, chronic visual loss who was noted to have a live, motile worm within the vitreous cavity.

Multimodal imaging-guided diagnosis, management and follow-up of a case of diffuse unilateral subacute neuroretinitis.

A 45-year-old woman presented with diminished vision in the left eye. Visual acuity was 6/9 and fundus showed a very large live nematode near the macula along with inflammatory outer retinal lesions in the periphery. We diagnosed the case as diffuse unilateral subacute neuroretinitis and treated with immediate focal photocoagulation of the worm along with oral antihelminthic drugs and corticosteroids.

Optical Coherence Tomography Angiography Findings in Diffuse Unilateral Subacute Neuroretinitis.

Background And Objective: To report a unique case series of diffuse unilateral subacute neuroretinitis (DUSN) patients imaged with optical coherence tomography angiography (OCTA).

Patients And Methods: In this retrospective case series, multimodal imaging was performed in four patients with DUSN at the time of patient visit. The study patients underwent standard clinical treatment for DUSN.

Diffuse unilateral subacute neuroretinitis: review article.

Diffuse unilateral subacute neuroretinitis (DUSN) is an ocular infectious disease that can lead to severe visual impairment and blindness. It usually occurs in healthy young individuals and depending on the stage of the disease, it may present as vitritis, multifocal gray-white lesions in the outer retina, and derangement of the retinal pigment epithelium, narrowing of the retinal vessels and optic atrophy. Parasites of different sizes and species have been proposed as the etiologic agent of DUSN, including Ancylostoma caninum, Toxocara canis, and others.

Diffuse Unilateral Subacute Neuroretinitis Evolving With Submacular Granuloma.

DUSN is an infectious ocular disease that can lead to severe visual impairment and blindness. It usually occurs in young healthy individuals and depending on the stage of the disease, clinical presentation may range from mild vitritis and multifocal gray-white lesions in outer retina to optic atrophy.Parasites of different sizes and species have been proposed as the etiological agent of this disease.

Role of PASCAL and optical coherence tomography angiograpgy in the treatment of diffuse unilateral subacute neuroretinitis caused by large live motile worm.

A 46-year-old male presented with best corrected visual acuity (BCVA) of 20/125 in his right eye. Fundus showed disc edema, multiple yellow outer retinal crops, macular edema and a live motile worm in the subretinal space. Diagnosis of diffuse unilateral subacute neuroretinitis (DUSN) was made and pattern scanning laser photocoagulation (PSLP) was performed along with administration of oral albendazole, diethylcarbamazine and corticosteroids.
