Screening for Oculocerebral Lymphoma with the Phenotype of NK Cells in Patients with Uveitis

Uveitis is an inflammation of the uvea, an ocular tunic comprising the iris, ciliary body and choroid. This inflammation can also involve other tissues such as the retina, the optic nerve and the aqueous humor. These diseases can result in significant vision loss and account for 10% of all blindness in developed countries, and up to 25% in developing countries. The main difficulty in this pathology is to make the etiological diagnosis, which then allows a specific treatment of the disease. The main etiologie are inflammatory or infectious (sarcoidosis, tuberculosis) but other cancerous etiologies are possible and are of more complicated diagnosis. Vitreoretinal lymphoma is a subtype of central nervous system lymphoma, which is generally associated with a poor prognosis. It is a diffuse non-Hodgkin's lymphoma, with large B cells. It can be primary ocular (Primary Intra-Ocular Lymphoma - LIOP), without brain involvement, but can also be secondary to central nervous system involvement, which explains the poor prognosis of the disease. Approximately 50-90% of LIOP develop brain involvement within 1-2 years of diagnosis, which encourages early diagnosis to avoid brain involvement as much as possible. The main obstacle to rapid diagnosis is the difficulty of identifying LIOP. Indeed, the clinical symptoms of this rare disease are often identical to classical uveitis, and the diagnostic means to detect it are invasive and require a trained ophthalmologist and hematologist team.
