Purpose: To report the clinical outcome of rhuthenium-106 plaque radiotherapy in acquired retinal pigment epithelial (RPE) tumors. Methods: In this interventional case series, two eyes of two patients with clinically diagnosed ocular-acquired RPE tumors including adenoma and adenocarcinoma underwent plaque radiotherapy with rhuthenium-106. The clinical findings and visual outcome of the patients were evaluated. Results: The first patient was a 44-year-old male, and the second was a 32-year-old female. The follow-up times were 24 and 32 months. The tumor was unilateral and hyperpigmented in both cases, located at juxtapapillary in one patient and on peripheral part of the retina in the other. Vitreous hemorrhage and peripheral exudation were obvious in one patient. Macular edema, epiretinal membrane, and retinal feeder vessels were also detected in the examination. The patients underwent plaque radiotherapy with rhuthenium-106 as the first step of management. The tumor has been stable until the last follow-up in both patients with globe preservation and acceptable visual acuity (5/10 for the first case and 4/10 for the second case). Conclusion: Rhuthenium-106 plaque radiotherapy might be a conservative therapy in the management of acquired RPE tumors and prevent early enucleation.
