Outline of Final Research Achievements

In the eyes with pathologic myopia, the deformity of posterior segment of the globe mechanically damages the retina and the optic nerve. In the present study, we have established novel models of experimental myopia by visual deprivation in rats. To prevent the scleral thinning and myopia progression, human skin-derived fibroblasts were transplanted along the outer surface of rat sclera before inducing myopia. In 1 week, the transplanted cells produced collagen in situ, and the recipient sclera had an increased thickness. In transplanted animals, the degree of induced myopia was less. The results showed that autologous fibroblast transplantation can be a novel, less-invasive therapy to prevent eye deformity in pathologic myopia.
