Abstract
PURPOSE: To evaluate treatment outcomes and complications of intravitreal rituximab (IVR) monotherapy for eyes with vitreoretinal lymphoma (VRL). METHODS: Patients diagnosed with 'isolated primary VRL' or 'VRL with remission of systemic disease' and treated with IVR (1 mg/0.1 ml) between June 2014 and June 2019 were included in this retrospective, interventional case series. Injections were repeated at monthly intervals until complete resolution. All patients signed a written informed consent form. Institutional review board approval was obtained. RESULTS: Twelve eyes of 7 patients with VRL were treated with 77 IVR injections at mean 6.42 injections per eye (median = 5; range = 2-13) for complete resolution at mean 8.16 ± 4.62 months (median = 6.97 months; range = 1.97-14.33 months). Mean age at presentation was 53.3 years (median = 54 years; range = 34-74 years). Patients were co-managed with medical oncologist and periodically evaluated. Complications included anterior uveitis (n = 6), raised intraocular pressure (n = 3), posterior synechiae (n = 2), vitreous haemorrhage (n = 1), pre-retinal haemorrhage (n = 1), retinal detachment (n = 1), posterior subcapsular cataract (n = 2) and sectoral iris atrophy (n = 1). Recurrences were seen in 3 eyes (25%), which eventually achieved complete resolution with treatment. None of the patients had systemic involvement or death during follow-up. Mean follow-up was 18.73 ± 8.83 months (median = 21.60 months; range = 7.37-32.67 months). CONCLUSION: Intravitreal rituximab monotherapy is effective in management of vitreoretinal lymphoma in patients with isolated ocular disease.
