Cell Replacement Therapy for Optic Nerve Disorders

Abstract

This review article explains major optic nerve disorders and cell replacement therapy. This article also signifies new innovative methods, biopharmaceuticals, implantable biomaterials, devices and diagnostic tools developed for restoration of vision. It asserts notable technological advancements made for regeneration of neurons and restoration of visual system network. However, for finding quick solutions of optical- neuronal disorders more advanced biomaterial cell scaffolds and concurrent efforts are needed to revitalize visual-neural receptor system. This article stresses upon novel bioengineered methods mainly required to activate endogenous stem and progenitor cells, which could reawaken cells in dormancy, instructing them to promote repair and regeneration in optic nerve cells and retina. For better management of optic nerve disorders, the important role of tissues, genes, growth factors and proteins, nanomedicine and nanotechnology, and all underlying mechanisms should fully be investigated. This article tries to explore all possibilities to find quick solutions for treatment of loss of vision/ photoreceptors and degeneration of optic neural network despite all ongoing challenges. Moreover, for solving visual disorders, neurodegenerative blinding diseases novel cell-based therapeutic strategies are to be developed with future applications in regenerative medicine.
