Bovine Pericardium for Scleral Closure in Transscleral Local Resection of Choroidal Melanoma

摘要

The current treatment of uveal melanoma aims to conserve the eye as well as useful vision. Conservative therapy includes brachytherapy, charged particle teletherapy, stereotactic radiotherapy, transpu-pillary thermotherapy, and transscleral local resection. Despite technical advances, local resection of poste- . rior uveal melanoma (choroidectomy and cyclocho-roidectomy) remains a challenging procedure, and therefore, it is indicated only in selected cases. Transscleral local resection should be performed for tumors whose larger basal diameter is less than 16 mm and whose thickness exceeds 8 to 9 mm; because in these cases, the incidence of complications related to radiotherapy increases and consequently the chances of conserving vision are reduced.
