Retinitis Pigmentosa News and Research RSS Feed - Retinitis Pigmentosa News and Research

Retinitis pigmentosa (RP) is the name given to a group of inherited eye diseases that affect the retina (the light-sensitive part of the eye). RP causes the breakdown of photoreceptor cells (cells in the retina that detect light). Photoreceptor cells capture and process light helping us to see. As these cells breakdown and die, patients experience progressive vision loss. The most common feature of all forms of RP is a gradual breakdown of rods (retinal cells that detect dim light) and cones (retinal cells that detect light and color). Most forms of RP first cause the breakdown of rod cells. These forms of RP, sometimes called rod-cone dystrophy, usually begin with night blindness. Night blindness is somewhat like the experience normally sighted individuals encounter when entering a dark movie theatre on a bright, sunny day. However, patients with RP cannot adjust well to dark and dimly lit environments.

Iodine supplement can reduce central foveal swelling in RP patients with CME

Iodine supplement can reduce central foveal swelling in RP patients with CME

Cystoid macular edema (CME) is a common complication of retinitis pigmentosa (RP), a family of retinal diseases in which patients typically lose night and side vision first and then develop impaired central vision. CME can also decrease central vision. [More]

New chemical compound protects against blindness and diabetes in animals

In a new study led by UC San Francisco scientists, a chemical compound designed to precisely target part of a crucial cellular quality-control network provided significant protection, in rats and mice, against degenerative forms of blindness and diabetes. [More]
New approach for developing personalized gene therapies to treat retinitis pigmentosa

New approach for developing personalized gene therapies to treat retinitis pigmentosa

Columbia University Medical Center researchers have created a way to develop personalized gene therapies for patients with retinitis pigmentosa (RP), a leading cause of vision loss. [More]
Light-sensitive molecule enables noninvasive silencing of neurons

Light-sensitive molecule enables noninvasive silencing of neurons

Optogenetics, a technology that allows scientists to control brain activity by shining light on neurons, relies on light-sensitive proteins that can suppress or stimulate electrical signals within cells. This technique requires a light source to be implanted in the brain, where it can reach the cells to be controlled. [More]

Researchers take step toward restoring natural, high-fidelity vision to blind people

Researchers take step toward restoring natural, high-fidelity vision to blind people

In laboratory tests, researchers have used electrical stimulation of retinal cells to produce the same patterns of activity that occur when the retina sees a moving object. Although more work remains, this is a step toward restoring natural, high-fidelity vision to blind people, the researchers say. [More]
