editorial: inherited retinal degenerations
in this issue of irjo movassat et al1 (p: 33-38) present a case series of leber's congenital amaurosis (lca). lca is the most severe form of inherited retinal dystrophy responsible for congenital blindness with an early age of onset and accounts for at least 5% of all inherited retinal diseases which affect about one in 3500 individuals in the world. usually degenerative anomalies of the r...
متن کاملEmerging gene therapies for retinal degenerations.
Introduction Our most cherished sense, vision, begins with the process of phototransduction, a process performed by the highly specialized photoreceptor cells of the retina: the rods and cones (Rodieck, 1998). Rod photoreceptor cells are needed for night vision, as they are able to respond to very few photons, while cones are active under bright light conditions and are responsible for color vi...
متن کاملProspectives for Gene Therapy of Retinal Degenerations
Retinal degenerations encompass a large number of diseases in which the retina and associated retinal pigment epithelial (RPE) cells progressively degenerate leading to severe visual disorders or blindness. Retinal degenerations can be divided into two groups, a group in which the defect has been linked to a specific gene and a second group that has a complex etiology that includes environmenta...
متن کاملRetinal remodeling triggered by photoreceptor degenerations.
Many photoreceptor degenerations initially affect rods, secondarily leading to cone death. It has long been assumed that the surviving neural retina is largely resistant to this sensory deafferentation. New evidence from fast retinal degenerations reveals that subtle plasticities in neuronal form and connectivity emerge early in disease. By screening mature natural, transgenic, and knockout ret...
متن کاملRole of Muller cells in retinal degenerations.
Muller (radial glial) cells span the entire thickness of the retina, and contact and ensheath every type of neuronal cell body and process. This morphological relationship is reflected by a multitude of functional interactions between retinal neurons and Muller cells, including extracellular ion homeostasis and glutamate recycling by Muller cells. Virtually every disease of the retina is associ...
