Clinical features predictive of vision loss in patients with vitreoretinal lymphoma: a single tertiary center...

To clarify the long-term visual prognosis and prognostic factors for vision loss in patients with vitreoretinal lymphoma (VRL). This retrospective longitudinal study included 64 consecutive patients with VRL. We analyzed the best-corrected visual acuity (BCVA), optical coherence tomography findings, and clinical features at every visit. Significant vision loss was defined as a final BCVA ≥ 0.5 logMAR. Predictors of significant vision loss following treatment were evaluated using univariate and multivariate linear regression analyses. We included 113 eyes of 64 patients (mean age, 64.2 ± 10.9 years), and 49 patients (76.6%) showed bilateral ocular involvement. The mean follow-up duration was 35.4 ± 25.8 months. At diagnosis, 36 (56.3%), 17 (26.6%), and 11 (17.2%) patients had primary, secondary, and concurrent VRL, respectively. All eyes received intraocular methotrexate injections (mean, 17.1 ± 5.5 injections). The mean BCVA improved from 0.44 ± 0.28 at diagnosis to 0.33 ± 0.29 1 month after treatment initiation. Vision improved significantly after treatment (final mean BCVA, 0.24 ± 0.21). Univariate and multivariate analyses showed that baseline BCVA and retinal/subretinal infiltration were significantly correlated with vision loss. In this study, a good visual outcome was maintained for > 35 months in patients with VRL. Baseline BCVA and retinal/subretinal infiltration were significant predictors of vision loss after treatment for VRL.
