Abstract
The present invention involves selectively breaking down or altering a blocking tissue by irradiating the blocking tissue with a laser irradiation. Breaking down the blocking tissue allows the delivery of therapeutic agents through the blocking tissue to a target tissue. An area of the blocking tissue is selected for treatment. The selected area is irradiated with a laser to induce an alteration or breakdown of the blocking tissue. Areas not irradiated are not affected. Once the selected area of the blocking tissue is treated, a therapeutic agent can be delivered to the selected area and passed through the altered or broken down blocking tissue to the target tissue. The blocking tissue will then undergo a healing response after a period of time. The present invention may be used to treat the retina or subretinal space of a patient's eye through the blocking tissue of the Retinal Pigment Epithelium (RPE).
