Age-related Macular Degeneration

…such as retinitis pigmentosa and age-related macular degeneration. However, the death of rods and cones allows retinoids to permeate the inner retina, causing retinal ganglion cells to become spontaneously hyperactive, severely reducing the signal-to-noise ratio, and creating interference in the communication between the surviving retina and the brain. Treatments aimed at blocking or reducing hyperactivity improve vision initiated from surviving photoreceptors and could enhance the signal fidelity genera

Age-related Macular Degeneration (AMD) and Retinitis Pigmentosa (RP) are vision disorders caused by loss of rod and cone photoreceptors, but downstream retinal neurons also show physiological and morphological changes, resulting in the emergence of hyperactivity and rhythmic firing in many retinal ganglion cells (RGC). We recently discovered that retinoic acid (RA) is a key signal that triggers hyperactivity and that blockers of RA unmask light responses in RGCs that would otherwise be obscured. Recent work is revealing where in the retina circuit RA initiates functional changes. Moreover, int
