Researchers at Georgia Institute of Technology have developed an innovative method to treat two major eye diseases, glaucoma and corneal neovascularization, by using micro-needles that range from 400 to 700 microns. These micro-needles allow targeted treatment that can lead to a more efficient treatment and lower risk of side effects. Before, the only way to treat ocular diseases was through applying medicine to the whole surface of eye or through surgical methods. Because many of these drugs have detrimental effects on the healthy part of the eye, many patients have experienced severe side effects. According to the researchers, “the micro-needle therapy would inject drugs into space between two layers of the eye near the ciliary body, which produces the aqueous humor.” The researchers hope to further develop the micro-needle therapy so that it can also treat other types of diseases.
