  • Publication number: 20170274005
    Abstract: Disclosed is a complex for remedying or treating a retinal disease. The complex includes a hyaluronic acid or a derivative thereof, a carbon nanomaterial covalently bonded to the hyaluronic acid or the derivative thereof, and a photosensitizer bonded to the carbon nanomaterial. The complex for remedying or treating the retinal disease according to the present invention includes a hyaluronic acid-carbon nanomaterial-photosensitizer complex, thus selectively preventing the formation of active oxygen in retinal pigment epithelium cells for a relatively long period of time. Accordingly, the complex has excellent therapeutic efficacy and easily infiltrates into cells. Further, the present invention provides a composition for remedying or treating a retinal disease including the hyaluronic acid-carbon nanomaterial-photosensitizer complex.
