Stem Cell Treatmtent for Retinitis Pigmentosa
Retinitis Pigmentosa treatments using stem cells is now an option...
Retinitis pigmentosa is a group of genetic eye conditions that leads to incurable blindness. In the progression of symptoms for Retinitis pigmentosa, night blindness generally precedes tunnel vision by years or even decades. Many people with Retinitis pigmentosa do not become legally blind until their 40s or 50s and retain some sight all their lives. Others go completely blind from Retinitis pigmentosa, in some cases as early as childhood. Progression of Retinitis pigmentosa is different in each case.
Retinitis pigmentosa is a type of progressive retinal dystrophy, a group of inherited disorders in which abnormalities of the photoreceptors (rods and cones) or the retinal pigment epithelium of the retina lead to progressive visual loss. Affected individuals first experience defective dark adaptation or nyctalopia (night blindness), followed by reduction of the peripheral visual field (known as tunnel vision) and, sometimes, loss of central vision late in the course of the disease.

Int J Mol Sci. 2016;17(3) Authors: Ouyang H, Goldberg JL, Chen S, Li W, Xu GT, Li W, Zhang K, Nussenblatt RB, Liu Y, Xie T, Chan CC, Zack DJ Abstract Stem cells hold promise for treating a wide variety of diseases, including degenerative disorders of the eye. The eye is an ideal organ for stem cell therapy because of its relative immunological privilege, surgical accessibility, and its being a self-contained system. The eye also has many potential target diseases amenable to stem cell-based treatment, such as corneal limbal stem cell deficiency, glaucoma, age-related macular degeneration (AMD), and retinitis pigmentosa (RP). Among them, AMD and glaucoma are the two most common diseases, affecting over 200 million people worldwide. Recent results on the clinical trial of retinal pigment epithelial (RPE) cells from human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs) in treating dry AMD and Stargardt's disease in the US, Japan, England, and China have generated great excitement and hope. This marks the beginning of the ocular stem cell therapy era. The recent Zhongshan Ophthalmic Center Ocular Stem Cell Symposium discussed the potential applications of various stem cell types in stem cell-based therapies, drug discoveries and tissue engineering for treating ocular diseases.
