Intraretinal worm documented by optical coherence tomography in a patient with diffuse unilateral subacute neuroretinitis: case report.
نویسندگان
چکیده
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.

Purpose Diffuse unilateral subacute neuroretinitis (DUSN) is often a challenging diagnosis to make. We present a DUSN case with its multimodal imaging to aid in the diagnosis, emphasizing the observations on optical coherence tomography angiography (OCTA). Observations The evolution of a DUSN case is presented. Fundus photography and OCTA aided in the identification of the nematode. Conclus...

The clinical syndrome of diffuse unilateral subacute neuroretinopathy (DUSN) has been characterised in its early and late stages. Different types of migrating worms in the subretinal and intraretinal space have been described as the cause of the clinical syndrome. We observed a patient with a long history of visual loss, vitritis, and a fundus of abnormal appearance where the worm was noted to ...
