1. A method for epiretinal treatment of a subretinal target tissue in an eye having a sclera and a retina, comprising the steps of:
- introducing an ionizing radiation source through the sclera into the interior of the eye;
locating the radiation source with respect to the subretinal target tissue to expose the target tissue to radiation passing through the retina; and
irradiating the target tissue through the retina with an effective amount of radiation.

Abstract
A method for performing intraocular brachytherapy and an apparatus for performing the same is disclosed. The apparatus preferably comprises a hand-held delivery device that advances a radiation source into an associated cannula or probe that is positioned adjacent the target tissue. The handpiece provides for shielded storage of the radiation source when retracted from the cannula and includes a slider mechanism for advancing and retracting the radiation source. The radiation source is mounted to a wire that has a flexible distal end and a relatively stiffer proximal end.
