Light and Electronmicroscopic Study of Tree Shrew Sclera During NormalDevelopment, Induced Myopia and Recovery

摘要

In the developing eye of humans and other animals, it appears that an'emmetropization' mechanism guides most eyes toward emmetropia, a condition where there is no refractive error. This mechanism appears to control axial length of the eyes so that the plane of the retina gradually matches the plane of focus. Control of axial length during development may involve controlling the development of the sclera, a fibrous tissue providing structural integrity and resistance to the expansive forces of intraocular pressure.
