Spectral domain optical coherence tomography (SD-OCT) images showing progressive retinal damage by ocular toxocariasis granulomas.

<p>(A) Before discontinuous migration, a normal macular structure is visible, but scattered hyper-reflective dots indicate vitritis. (B) After discontinuous migration from the peripheral retina to the macula, a macular granuloma is observed in the inner retinal layers. (C) One month later, the inner retinal layers show severe distortion, a thick epiretinal membrane is present, and the granuloma extends to the outer retinal layers. (D) Three months after vitrectomy and epiretinal membrane removal, structural damage has not completely resolved.
