Patent ID: 7744520

Claim:
A method for delivering radiation to a target tissue comprising sub-macular choroidal neo vascularization (CNV) associated with macular degeneration in an eye from the interior of the eye with a radiation delivery device having an elongated probe associated therewith, the probe having a distal end through which radiation can be selectively administered to the target tissue, the method comprising: creating an access to the interior of the eye through a surface of the eye; introducing the probe into the interior of the eye through the access; positioning the distal end of the probe a predetermined distance from the target tissue; protecting non-target tissue from radiation emitted from the distal end of the probe by introducing a radiation attenuating fluid into the interior of the eye; delivering a dose of radiation to the target tissue, including attenuating the peak radiation dose delivered by the probe to the target tissue closest to the distal tip of the probe.
