Background: The relative rarity of retinal vasoptoliferative tumors has resulted in a lack of ecidence-based consensus agreement on how best to treat these
lesions. Therefore, there is a need for advanced techniques capable of more effective treatment of these tumors and allowing for the preservation of visual
function.
Purpose: To review the results of treatment of large retinal VPTs by pars plana vitrectomy with tumor endoresection and the use of high-frequency electric
welding (HFEW) for achieving hemostasis.
Material and Methods: We reivewed the results of surgical treatment of large retinal VPTs complicated by exudative retinal detachment, macular edema,
and/or epiretinal fibrosis in 5 patients (6 eyes)
