Research Study of New Treatment Called NT-501 (Encapsulated Cell Therapy (ECT) Implant) for Glaucoma
Condition: Eye / Glaucoma
Investigator: George Cioffi, MD
Status: Closed
Glaucoma is a given name of a group of diseases that affect the retinal ganglion cells in the eye and the optic nerve. Glaucoma cause degeneration of the retinal ganglion cells in the retina and their projections (axons) that form the optic nerve. Retinal ganglion cells and their axons transmit all of our vision information from the eye to the brain through…
