Abstract
Methods and devices for minimally-invasive delivery of radiation to the posterior portion of the eye including a cannula comprising a distal portion connected to a proximal portion and a means for advancing a radionuclide brachytherapy source (RBS) toward the tip of the distal portion; a method of introducing radiation to the human eye comprising 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 said sclera.
Claims46
A method of irradiating a target of an eye in a patient, said method comprising:
- (a) inserting a cannula into a potential space under a Tenon's capsule of the eye of the patient, the cannula configured to have a radionuclide brachytherapy source (RBS) at a treatment position,
- (b) observing through a pupil the position of the treatment position in a posterior pole of the eye,
- (c) adjusting the cannula that is under the Tenon's capsule to achieve fine positioning of the treatment position, the fine positioning is achieved when the treatment position is over a target,
- (d) irradiating the target with the RBS.
The method of claim 11, wherein the cannula is a flexible cannula, including an endoscope.
