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

Am J Ophthalmol Case Rep. 2021 May 12:23:101112. doi: 10.1016/j.ajoc.2021.101112. eCollection 2021 Sep.

Abstract

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.

Keywords: Diffuse unilateral subacute neuroretinitis; Enface swept source vitreous optical coherence tomography; Multicolor scanning laser imaging; Multimodal imaging; Nematode.
