PURPOSE: To evaluate the effectiveness and safety of intravitreal melphalan (IVM) injection therapy in vitreoretinal lymphoma.
METHODS: Eight eyes of five biopsy-proven vitreoretinal lymphoma patients who were treated with IVM injection as a second-line therapy after intravitreal methotrexate and rituximab injections were retrospectively evaluated between January 2011 and March 2023.
RESULTS: The medical records of five vitreoretinal lymphoma patients (mean age of 62 years at the diagnosis) including 4 (80%) female patients and 1 (20%) male patient were retrospectively analyzed. Three patients (60%) either had a history of central nervous lymphoma or developed it during the follow-up. Patients were previously treated with a mean of five cycles of monthly intravitreal methotrexate and rituximab injections. All eyes showed complete response by the disappearance of vitreal and/or subretinal neoplastic cells within 6 weeks after IVM injections (range, 1-4 injections per eye). Of 12 IVM injections, 3 (25%) injections were associated with macular edema diagnosed on optical coherence tomography at 1-month follow-up and resolved spontaneously within 5 months. The IVM administration induced new retinal pigment epithelium changes in three eyes (37%).
CONCLUSION: Intravitreal melphalan injection may be effective in the management of vitreoretinal lymphoma as a second-line local therapy. Randomized clinical trials with larger numbers of patients are needed to establish the efficacy, treatment protocol, and safety of IVM injection.
