PURPOSE Primary intraocular lymphoma is a high-grade non-Hodgkin lymphoma with a pathogenesis that is still unclear. Microenvironment is known to be crucial in controlling tumor growth and maintenance. To study the immune microenvironment in intraocular lymphomas and to characterize the cytokine polarization of infiltrating T-lymphocytes, a new murine model of intraocular B-cell lymphoma was de...
The evaluation of intraocular tumors differs from almost all other oncologic evaluations because there is little reliance on tissue diagnosis. Definitive therapies such as enucleation and radiation are usually based on the results of ophthalmoscopy and a limited number of ancillary studies without the aid of biopsy. Although biopsies can be performed on most intraocular tumors, the ocular morbi...

Intraocular lymphangiogenesis in malignant melanomas of the ciliary body with extraocular extension.
PURPOSE To analyze whether lymphatic vessels can invade the normally alymphatic eye (lymphangiogenesis) in patients with malignant melanoma of the ciliary body with extraocular extension and to correlate these findings with metastasis-free survival. METHODS Ten enucleated globes with the histopathologically and immunohistochemically (S-100, HMB-45, PNL-2, and Melan-A) confirmed diagnosis of m...
Uveal melanoma (UM) is the most common adult intraocular tumor. UM often involves activating mutations in guanine nucleotide binding protein (G protein), q polypeptide (GQ), or G Protein, α 11 (G11). We show that the Yes-associated protein (Yap) inhibitor verteporfin blocks tumor growth of Gq/11-mutated UM cells.
