The subretinal worm causes a spectrum of diseases known as diffuse unilateral subacute neuroretinitis, involving the outer retina and retinal pigment epithelium (RPE).[1] RPE tracts are formed along their path of motion in the later stages.[2] Benign complications like macular cyst have been described in association with this entity.[3] Most cases, when diagnosed early, are treated with laser photocoagulation. We report the development of choroidal neovascular membrane (CNVM) formation in an eye with a dead subretinal worm in a 49-year-old male, who was treated with anti-vascular endothelial growth factor injection [Figure 1].
Figure 1: (a) Shows ultra-wide field fundus image of the left eye depicting a long and wavy subretinal tract (red arrow) with a grayish lesion at the macula (blue arrow); (b) Red-free fundus image clearly delineating the extent of the tract; (c) Choriocapillaris slab from optical coherence tomography angiography with a large choroidal neovascular membrane at fovea; (d) Corresponding structural OCT image showing increased retinal thickness, intraretinal fluid, subretinal hyper-reflective material, and disrupted ellipsoid layer, with increased flow as noted at the level of CNVM.
