Retinitis pigmentaria

People with disabilities are no different from anyone else. We all have strengths and challenges, and we all seek to be fully engaged in society. Treating blind people differently, either as incapable of conducting everyday tasks in life, or conversely, acting as though our ability to conduct even the most mundane chore is remarkable can be discouraging.

The Foundation Fighting Blindness is pleased to provide an audio recording and full transcripts of the Insights Forum, our quarterly conference call providing updates to the inherited retinal disease community. The call took place on January 31, 2020.

My Retina Tracker Program is the highest volume IRD genetic testing program in the U.S.

Known as Pro-EYS, the study will help researchers design clinical trials for potential therapies

Improved outcome measures will make clinical trials for degenerative retinal diseases — including age-related macular degeneration (AMD), the world’s leading cause of blindness in seniors, and inherited retinal conditions such as RP and Stargardt disease — less expensive to conduct and able to deliver more precise results.

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.

Both approaches show strong, near-term potential for providing meaningful vision to people who are otherwise blind from retinal diseases such as retinitis pigmentosa and age-related macular degeneration (AMD).

The powerful and secure system enables patients to keep track of their clinical care and vision changes. At the same time, it enables scientists to search the “de-identified” (i.e., anonymous) patient information to study conditions and identify targets for treatments, preventions and cures.

Simply put, they’re creating therapies that can save vision in as many people as possible, independent of the genetic cause of disease.

Non-24 is a very rare condition affecting many (but not all) people who are totally blind and have absolutely no light perception. Their circadian clocks become out of sync as a result.

Dr. Henry Klassen’s progenitor-based therapy has the potential to rescue a variety of retinal cells — including rods, cones, retinal pigment epithelium and ganglion cells — and, therefore, may save vision in people with a wide range of conditions.

Known as EZ Width, it holds potential for reducing the time, cost and number of patients needed to determine if a therapy is working in a clinical trial.

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.
