Figure 1. Photomicrographs of vitreous cytopathology in patients with clinical suspicion of IOL.

A: Diffuse large B-cell lymphoma in case 1 with aggregation of large pleomorphic mononuclear cells with irregular nuclei, prominent nucleoli and atypical mitosis in a vitreous cytospin preparation (Giemsa stain,×1000); B: Intraocular T cell lymphoma in case 7 with the presence of atypical lymphoid cells with mitosis, lack of immune-reactivity for CD20 (×400) and diffuse immune-reactivity (inset) for CD3 (×600); C: Nonspecific chronic inflammation in case 4 with the presence of small lymphocytes and no atypical features (hematoxylin & eosin,×400); D: Non-diagnostic and hypocellular vitreous specimen in case 8 with the presence of few red blood cells and few macrophage-like cells (hematoxylin & eosin, ×400).
