The first type, known as primary intraocular lymphoma (PIOL), is mainly recognized as a subtype of primary central nervous system lymphoma (PCNSL). Recent classifications have emphasized the primary ocular sites affected, with vitreoretinal lymphoma emerging as the most common variant linked to PCNSL. Despite its rarity, the incidence of PIOL is rising among both immunocompromised and immunocompetent populations. Most cases of PIOL are identified as diffuse large B-cell lymphoma, although rare T-cell variants have also been reported. Secondary intraocular lymphoma (SIOL) originates from metastatic spread of non-CNS lymphomas to the ocular structures, including the retina, uvea, vitreous body, Bruch's membrane, and optic nerve. Diagnosis of IOL is challenging for ophthalmologists and pathologists, as it can easily mimic other ocular conditions.
