In a quiet Craftsman-style home, the Barker family gathers around ordinary moments—making apple crisp, sharing laughter with a rescue dog circling the kitchen island. These moments matter deeply, because behind them lives an extraordinary story of resilience, love, and determination.
For Shannon and Tom Barker, both professors at the University of Virginia, life changed with a diagnosis delivered when their son Leo was just 10 years old. The news confirmed that Leo had choroideremia, a rare, incurable, X-linked disease that slowly steals eyesight. Shannon later reflected on the moment the reality truly set in:
“I don’t think we thought a lot about it … and then the diagnosis made it real. And then, I couldn’t compartmentalize it anymore and then we had to come to terms.”
The disease was not unfamiliar to the family. Leo was named after his grandfather, who also lived with choroideremia. Knowing there was a 50-50 chance their son carried the gene, Shannon and Tom chose to delay testing, wanting to give Leo “those years of worry-free quote, unquote, time with him,” as Tom explained. When night vision problems appeared, they faced the truth together—with care, patience, and intention.
Even the first words from the doctor carried a stark gravity. Tom remembered:
“The first words out of this guy’s mouth were, ‘You’re very lucky.’ … He says, ‘Yeah, because the Virginia School for the Blind is only 30 minutes away.’”
Yet this story is not one of surrender. It is one of action.
After decades spent researching lung fibrosis—a disease that heartbreakingly took his own father just months after diagnosis—Tom made a life-altering decision. He reimagined his lab and redirected his expertise toward choroideremia. Not to claim an immediate cure, but to do something just as powerful: slow the disease long enough for hope to catch up.
“I said, ‘You know what? I just need to buy my son a decade,’” Tom said. “Our approach really is, ‘Let’s not try to hit the home run. Let’s try to get a double.’”
That decade represents possibility. Time for science to advance. Time for Leo to grow, learn, and live fully. Time for “really smart people” to continue the global search for a cure.
Throughout it all, Leo remains a source of light. He attends Mountaintop Montessori School, surrounded by classmates who stand with him—sometimes literally—by wearing hats and sunglasses in solidarity. Leo describes his world simply and joyfully:
“Everyone’s, like, my friend. That’s not a brag or anything, but, like, I got a billion friends.”
Before ever sharing the diagnosis with their son, Shannon and Tom made a conscious effort to show him what was possible. They shared stories of people with impaired vision thriving as engineers, musicians, and coders. As Shannon explained, they wanted Leo to understand “that doesn’t mean the end of the world. That there’s still … opportunities for a full life.”
That belief extends beyond their home. Tom’s lab has rallied students, researchers, and supporters, including those running the Marine Corps Marathon to raise funds for the Choroideremia Research Foundation. Their team name—Finish Line Vision—captures both urgency and hope.
This is a story about science, yes—but even more, it is about love. About a father who refuses to stop moving forward. About parents who prepare their child not for fear, but for confidence. About a community that runs, researches, and believes together.
In the face of an incurable disease, the Barkers are doing something profoundly human: turning uncertainty into purpose, and time itself into a gift.
