METHOD AND DEVICE FOR MINIMALLY-INVASIVE EXTRAOCULAR DELIVERY OF RADIATION TO POSTERIOR PORTION OF EYE

摘要

PROBLEM TO BE SOLVED: To provide methods and devices for minimally-invasive delivery of radiation to the posterior portion of the eye.SOLUTION: The methods and devices for minimally-invasive delivery of radiation to the posterior portion of the eye includes a cannula comprising a distal portion 110 connected to a proximal portion 120, and means for advancing a radionuclide brachytherapy source (RBS) toward a tip 200 of the distal portion. A method of introducing radiation to the human eye comprises inserting a cannula between the Tenon's capsule and the sclera of the human eye and emitting the radiation from the cannula on an outer surface of the sclera.
