This document discusses ocular lymphoma, including its presentation and subtypes. Lymphoid tumors represent about 10% of biopsy-proven orbital disorders. The orbit is an extranodal site that can be involved with lymphoma originating from the orbit, adnexa, or intraocular structures. Ocular manifestations can masquerade as other conditions like uveitis. Primary orbital and ocular adnexal lymphomas typically present with painless proptosis or diplopia. Diagnosis involves laboratory tests, imaging like B-scan ultrasonography, and biopsies of affected tissues. The document outlines different subtypes of B-cell and T-cell lymphomas that can involve the orbit, adnexa, or
