Some process can excites its natural apoptosis. RNFL is a sensitive structure which may vary based on ethnicity. The sparing of this layer is important in the treatment of the disease as it is the basis for connecting retinal prostheses to the optic nerve, or implanting stem cells that could regenerate the lost photoreceptors. However the thickness of the RNFL also decreases with age and not visual acuity. ![]() Patients with retinitis pigmentosa have abnormal thinning of the RNFL which correlates with the severity of the disease. Most of the fibers are centripetal, and are the direct continuations of the axis-cylinder processes of the cells of the ganglionic layer, but a few of them are centrifugal and ramify in the inner plexiform and inner nuclear layers, where they end in enlarged extremities. ![]() When they reach the internal surface of the retina they radiate from their point of entrance over this surface grouped in bundles, and in many places arranged in plexuses. In the anatomy of the eye, the retinal nerve fiber layer ( RNFL) or nerve fiber layer, stratum opticum, is formed by the expansion of the fibers of the optic nerve it is thickest near the optic disc, gradually diminishing toward the ora serrata.Īs the nerve fibers pass through the lamina cribrosa sclerae they lose their medullary sheaths and are continued onward through the choroid and retina as simple axis-cylinders.
