Episcleral brachytherapy as an effective alternative in vasoproliferative tumors

The aim of this study is to assess the results of episcleral brachytherapy as treatment of retinal vasoproliferative tumors (RVTs) in a referral Intraocular Tumors Unit (ITU). A retrospective review of all patients diagnosed with vasoproliferative tumors of the retina and treated with episcleral brachytherapy in the ITU, University Hospital of Valladolid between 2009 and 2015 was done. Five patients accomplished the inclusion criteria. All of them presented associated exudation and secondary retinal detachments (RD). Four patients had received prior treatments. Decreased tumor size and exudation regression was found in all cases after treatment. Visual acuity remained stable or increased in all patients. No recurrences have been found after twelve-months follow up. The results of the present study suggest that episcleral brachytherapy is an efficient and safe option in the management of vasoproliferative tumors, especially when large tumor or extensive subretinal fluid is present. In these cases episcleral brachytherapy could be considered as a first line treatment
