By changing the identity of cells in the retina–namely rods–researchers may someday be able to slow or halt vision loss for those with retinitis pigmentosa (RP) and other related conditions.

Understanding the pathways of the retinal neural network — and how they are rewired with aging and disease — is helpful in trying to save and restore vision.

Dr. Shinya Yamanka discussed his early clinical trial for iPSC-derived retinal pigment epithelial (RPE) cells for a 78-year-old woman with advanced wet age-related macular degeneration (AMD).

The complex and elusive nature of these conditions can also extend to the way they are passed down in families, making diagnosis and prognosis quite challenging.

RetroSense’s optogenetic therapy is designed to restore vision to people who are completely blind from retinal degenerative diseases such as retinitis pigmentosa by bestowing light sensitivity to retinal ganglion cells, which survive after photoreceptors, the cells that make vision possible, are lost.

The Foundation Fighting Blindness is, of course, all about finding treatments and cures for retinal degenerative diseases. However, we are well aware that many of our constituents and their families are dealing with more than just vision loss. That’s because genetic defects causing retinal conditions can sometimes affect other parts of the body. The result is conditions often referred to as syndromes.

Identifying the genes and proteins that play a major role in retinal health and vision is an important step in finding preventions and cures for degenerative diseases.

Many registries enable patients to collect and track information about their health, so they can take an active role in managing their care.

There’s hope for retinal regeneration for humans, thanks to Foundation-funded researcher Dr. Thomas Reh, who is investigating how to derive new photoreceptors from retinal cells called Muller glia.

The goal, “to regenerate the neurons and neural connections in the eye and visual system,” is exactly what people with retinal diseases need to save and restore their vision.
