    Abstract:
    BACKGROUND: To identify retinal changes using spectral-domain optical coherence tomography (SD-OCT) and ultra-widefield images in eyes with primary vitreoretinal lymphoma (PVRL) during intravitreal methotrexate (MTX) treatment.  METHODS: This study retrospectively reviewed 111 eyes of 58 patients with vitreous cytology-proven confirmed PVRL, who received intravitreal injections of MTX. RESULTS: At the initial visit, the OCT manifestations included vitreous cells (105 eyes, 94.6%), intraretinal infiltration (44 eyes,39.6%), subretinal infiltration (45 eyes, 40.5%,), retinal pigment epithelium (RPE) abnormalities (66 eyes, 59.5%), disruption of the ellipsoid zone (58 eyes, 52.3%), subretinal fluid (4 eyes, 3.6%), RPE detachment (PED) (28 eyes, 25.2%), epiretinal membrane (ERM) (8 eyes, 7.2%), macular edema (10 eyes, 9%). After therapy, tumor regression was achieved in all eyes. Between the initial presentation and regression, the vitreous cells (94.6% vs. 0%, P < 0.001), intraretinal infiltration (39.6% vs. 0%, P < 0.001), RPE abnormalities (59.5% vs.19.8%, P < 0.001), PED (25.2% vs.0%, P < 0.001), and subretinal infiltration (40.5%vs.16.2%, P < 0.001) were significantly reduced. The fundus photography findings all improved after therapy. The mean Logarithm of the Minimum Angle of Resolution (logMAR) for the best corrected visual acuity (BCVA) at presentation was 0.79 ± 0.81 (range, 0-2.9), which improved to 0.70 ± 0.97 (range, 0-2.9, P = 0.01) at the final visit. CONCLUSIONS: SD-OCT combined with ultra-widefield imaging, which can reflect retinal changes, are valuable tools for monitoring the effect of PVRL treatment.
