Abstract
A method and apparatus for delivering an agent to structures of the eye using iontophoresis applied through the eyelid of a patient. A drug is introduced into the eye. A first electrode is in electrical communication with the eyelid and a second electrode is positioned in relation to the first electrode. The electrodes are energized to generate a current between the electrodes and through the eye that facilitates the selective dissemination of the agent throughout the eye. An apparatus for such iontophoresis administration includes a housing having an inner surface adapted to be in electrical communication with the eyelid. The first electrode is positioned in the housing and in electrical communication with at least a portion of the inner surface. The housing may also include a reservoir for holding an agent for introduction into the eye through the eyelid.
