Abstract:
1. A method of delivering radiation to a target at a posterior portion of an eye, said method comprising: (a) obtaining a brachytherapy-administering device adapted to be threaded through a suprachoroidal space of the eye, the device comprising a brachytherapy source and a means of advancing the brachytherapy source from a storage position to a radiation position, the radiation position corresponding to a position in a distal portion of the device; (b) performing surgical procedures at an incision site to reach the suprachoroidal space of the eye; (c) inserting the brachytherapy-administering device into the suprachoroidal space and threading the device appropriately through the suprachoroidal space wherein the device glides between the sclera and choroid tissue such that the distal portion of the device is in close proximity to the target, the target being a distance from the incision site; (d) advancing the brachytherapy source from the storage position to the radiation position; (e) exposing the target to the brachytherapy source for a predetermined length of time; (f) removing the brachytherapy-administering device from the suprachoroidal space; and (g) closing incisions made during the surgical procedures to reach the suprachoroidal space of the eye.
