Abstract
To present a standardized surgical technique for endoresection of uveal melanoma (UM) minimizing the risk of serious adverse events, including fatal gas embolism. Ten UM patients underwent endoresection following proton beam radiotherapy for radiotherapy-related vascular complications. Vortex veins located in correspondence of the tumor base had been cauterized at the time of tantalum markers placement. Endoresection was performed following complete 25G vitrectomy, endolaser and endodiathermy. The tumor was removed using a subretinal or transretinal approach depending on retinal infiltration. If needed, perfluorodecalin (PFD) was injected to stabilise the retina. Fluid-silicone oil (SO) or PFD-SO exchange was performed, avoiding air. Endoresection was successfully performed in all eyes with no intraoperative complications. Mean follow-up (FU) was 10.8 ± 3.2 months. One patient was enucleated due to neovascular glaucoma. At the last FU, the remaining patients had the eye preserved and no signs of local recurrence or neovascular glaucoma. Our standardized surgical technique for UM endoresection appeared to be safe, minimizing the risk of serious intraoperative and postoperative adverse events.
