transscleral local resection
A surgical technique involving removal of uveal tumors through a scleral incision while preserving the globe and remaining ocular structures.
Full Definition
Transscleral local resection is a globe-preserving surgical procedure used for the removal of selected uveal melanomas and other intraocular tumors. The technique involves creating a scleral flap or window overlying the tumor, followed by careful dissection and en-bloc removal of the lesion along with a margin of normal tissue. This approach allows for histopathological examination while potentially preserving useful vision, particularly for tumors in favorable locations. The procedure requires meticulous surgical technique to prevent tumor cell spillage and achieve negative margins. Postoperative complications may include retinal detachment, vitreous hemorrhage, and hypotony, requiring careful patient selection and experienced surgical expertise. Success rates and visual outcomes depend largely on tumor size, location, and patient factors.
Usage
Usage note: Emphasize globe preservation advantage; document selection criteria and potential complications.
