High-definition optical coherence tomography features of primary vitreoretinal lymphoma.

Primary vitreoretinal lymphoma is a high-grade intraocular malignancy that presents as a vitritis with creamy subretinal lesions. In cases where the vitritis is dense, the characteristic subretinal lesions can be difficult to see on clinical examination. Novel high-definition imaging techniques that allow for deeper penetration through opaque media could have diagnostic utility in such cases. The authors present a case of a patient who presented with a dense vitritis that precluded visualization of fundus details. Spectral-domain optical coherence tomography using high-definition raster imaging demonstrated subretinal deposits along with outer retinal atrophy. These findings were suggestive of primary vitreoretinal lymphoma and prompted diagnostic vitrectomy. Pathological examination of the vitreous specimen confirmed the diagnosis of primary vitreoretinal lymphoma.
