Eye-based lymphomas represent one of the most diagnostically challenging cancers in ophthalmology, often mimicking inflammatory conditions while progressing silently through the vitreous and retina. Understanding their clinical signature could dramatically improve early detection rates for this aggressive malignancy that frequently spreads to the brain.
Analysis of 138 newly diagnosed patients reveals vitreoretinal lymphoma predominantly affects older adults averaging 66 years, with men developing disease earlier than women. The cancer demonstrates a striking predilection for bilateral involvement in two-thirds of cases, with 90.6% showing vitreous infiltration and 60.1% retinal involvement. Nearly all cases represent diffuse large B-cell lymphoma, the most aggressive subtype. Concurrent central nervous system involvement occurred in 23.2% of patients, underscoring the cancer's neurotropic behavior. Optical coherence tomography detected abnormalities in 80.5% of cases, particularly subretinal and sub-retinal pigment epithelial nodules.
This registry data provides the largest systematic characterization of vitreoretinal lymphoma presentations to date, filling critical knowledge gaps for a cancer with historically poor diagnostic accuracy. The high rate of bilateral disease challenges traditional assumptions about unilateral eye cancers, while the frequent vitreous involvement explains why patients are often misdiagnosed with chronic uveitis. The substantial overlap with CNS disease reinforces the need for neuroimaging in all cases. However, the registry's geographic limitations and potential referral bias toward more complex cases may not fully represent community presentations. For clinicians, these findings establish clearer diagnostic criteria for a cancer where delayed recognition often proves fatal.
