What Everyone with a Retinal Disease Should Know about Vitamin A

blue eyeIf you think of your retinas as the engines that power your vision, then vitamin A is their fuel. Without vitamin A in our diets, we wouldn’t see.

CME – What It Is, and Why People with Retinal Diseases Should Know About It

Dr. FishmanIn this Q&A, Gerald Fishman, M.D., a world-renowned clinical researcher and longstanding member of FFB’s Scientific Advisory Board, discusses cystoid macular edema (CME), a potentially damaging accumulation of fluid in the retina affecting up to 32 percent of people with retinitis pigmentosa (RP) and related conditions. It’s a complication that can make matters worse for retinas already fragile from degenerative disease. While diagnosis isn’t always straightforward, CME can be treated to minimize vision loss.

FFB Goes Live to Help Save Vision

Save Your Vision Live!It’s no mystery that the Foundation Fighting Blindness’ core mission is funding research for treatments and cures of retinal diseases, and that we’re making significant progress. A recent influx of clinical, or human, trials of drug, gene and stem-cell therapies is proof. But another key FFB focus is informing the masses about retinal diseases through our public health-education program.

ARVO 2014: Three Promising CEP290 Gene Therapy Alternatives

Renee Ryalls explains the dual-AAV gene therapy she's developing.While gene therapies for retinal degenerative diseases are making groundbreaking strides in both human and laboratory studies, the most widely and successfully used human-engineered virus for delivering replacement genes to retinal cells — the adeno-associated virus, or AAV — has one significant limitation. It can’t deliver relatively large genes, namely those larger than about 4.5 or 5 kilobases (kb). (Bases are the building blocks of a gene, and its size is expressed in kilobases.)

Stem Cells Derived from Patient’s Skin Provide Insights into AMD

Dr. Stephen TsangInduced pluripotent stem cells (iPSC) — stem cells derived by genetically tweaking a small sample of a person’s skin or blood — are again demonstrating their power for helping researchers fight retinal diseases.

In this latest development, Stephen Tsang, M.D., Ph.D., a Foundation-funded researcher at Columbia University, used them to create a human model of age-related macular degeneration (AMD). The advancement not only gives us a better understanding of how AMD occurs; it provides a new, and potentially better, platform for testing vision-saving therapies. Results of the study were published in Human Molecular Genetics.

All-Star Vision

When the Baltimore Orioles’ Adam Jones makes a great catch — a feat the Gold Glove centerfielder accomplishes on a regular basis — he isn’t thinking about his retinas. But in the five seconds it takes a baseball to leave an opponent’s bat and reach Jones’ glove, his retinas are processing an enormous amount of real-time visual information — continual changes in the contrast, velocity and trajectory of the ball as it rockets out of the infield, reaches high into the stadium lights (or the sun) and descends into the outfield.

FDA Approval of an iPhone Eye Test

Example Interface of the myVisionTrack app.

Retinal diseases may be incurable, at the moment, but, with the help of specialized training and technology, they are not unmanageable. In fact, a savvy patient working with a conscientious eye doctor can adjust relatively well to the various stages of vision loss — via, for instance, mobility or assistive-technology training. And in the case of wet age-related macular degeneration, or AMD, there are treatments that slow vision loss.

Appreciating the Beauty of the Retina

An image of a mouse retina captured by Dr. Luca Della Santina, University of Washington. The retina is an amazingly elegant and complex tissue lining the back of the eye. Retinas make vision possible; without them, we can’t see. But most people never think about their retinas —  unless, of course, they have a retinal condition affecting their vision.

I’ll always remember my first Foundation Fighting Blindness conference, when I heard Dr. Dean Bok, of the University of California, Los Angeles, discuss the retina’s design and how it worked. I was new to the field and just learning. Dr. Bok opened his presentation by saying that, as a student, he was “seduced” by the beauty of retinal science. By the end of his impassioned talk, I, too, was hooked.

My Race to Cure Blindness

Michael Stone in a bike race Although a disease called cone-rod dystrophy has rendered me legally blind, I’m known, in certain circles, as a world-class triathlete. I swim as well as bike and run (often on mountain trails). I began competing before my vision deteriorated, and I’ve since learned to use my other senses. In fact, I like to think of my feet as my eyes. I take an awful lot of steps, and I don’t land heavily. If I’m on a trail and step on something that doesn’t feel right, I hop off, then move quickly forward. It’s usually on the run where I beat my competition.

But you know what? I can no longer shop for groceries.

Curing Blindness, Part 2: Dick’s Story

Image of Dick CoulsonTwo days ago, as part of FFB’s “Light the Way to a Cure” fundraising campaign, I shared the story of Corey Haas, as an example of clinical trial participants benefitting from gene therapy studies the Foundation supports. In his case, the therapy’s for a retinal disease called Leber congenital amaurosis. Today, I’d like to share the story of Dick Coulson (pictured, left), who has age-related macular degeneration (AMD), the leading cause of blindness in people age 55 and older. It’s also the target of two treatments that are currently in clinical, or human, trials, both of which are derived from stem cells.
