Endoresection of the Tumor Scar or Transpupillary Thermotherapy for the Treatment of Large Uveal Melanomas (Endoresection-Laser)

August 7, 2025 updated by: Institut Curie

Phase II Evaluating Endoresection of the Tumor Scar or Transpupillary Thermotherapy When Endoresection is Not Feasible After Proton Beam Therapy for the Treatment of Large Uveal Melanomas

Study the efficacy of endoresection of the tumor scar or, when surgery is not possible, transpupillary thermotherapy on the tumor scar to prevent neovascular glaucoma and secondary enucleation
