When most people hear the word cataracts, they think of ageing. Yet cataracts can also occur in infants and children, sometimes serving as an early clue to a much broader health condition. A new National Institutes of Health grant awarded to pediatric ophthalmologist Dr. Jennifer Rossen aims to better understand those connections and improve how children with cataracts are evaluated and treated.
Dr. Rossen, of Ann & Robert H. Lurie Children's Hospital of Chicago, recently received a $1 million, five-year grant from the National Eye Institute to study the genetics of pediatric cataracts. Her work will focus on creating a comprehensive database that links genes associated with childhood cataracts to potential inherited diseases, helping clinicians identify conditions that may otherwise go undetected.
When cataracts appear early in life
Unlike age-related cataracts, pediatric cataracts are often inherited and can be associated with a wide range of genetic syndromes. In some cases, the clouding of the eye's lens may be one of the earliest visible signs of a condition affecting other parts of the body.
Researchers estimate that pediatric cataracts may be linked to more than 200 syndromes. Some of these conditions are treatable if identified early, making timely diagnosis especially important. However, the underlying cause is not always investigated, which can delay access to appropriate screening and care.
The challenge is that clinicians often focus on managing the cataract itself, while the broader genetic picture may remain unexplored.
The genetic clues behind pediatric cataracts
Dr. Rossen's project will evaluate all candidate genes associated with pediatric cataracts and develop an AI-assisted, web-based database that clinicians can access freely. The goal is to create a practical resource that helps healthcare providers understand which inherited conditions may be associated with a child's cataract diagnosis.
By bringing together genetic information and disease associations in a single platform, the project hopes to simplify what can currently be a complex and fragmented process.
Improved access to genetic information may help clinicians identify children who require additional testing, specialist referrals, or monitoring for systemic conditions that extend beyond the eyes.
Why testing remains underused
Despite advances in genetic medicine, testing is not routinely performed for every child diagnosed with cataracts. Dr. Rossen's research will examine current practice patterns and identify barriers that may be limiting wider adoption.
Cost, access, awareness, and variability in clinical practice can all influence whether genetic testing is offered. Understanding those barriers is an important part of determining how testing can be integrated more consistently into patient care.
For some children, genetic testing may reveal a treatable inherited condition that would otherwise remain undiagnosed. Identifying those patients earlier could lead to better visual outcomes and improved overall health management.
“Cataracts in children may be the first sign of an underlying treatable inherited syndrome, and yet genetic testing is seldom used.”

Building a clearer path to early diagnosis
The project will also assess how effectively genetic testing identifies treatable diseases in children with cataracts. This evidence could help support more standardized approaches to care and provide clinicians with stronger guidance when evaluating young patients.
While genetics has become a major focus within retinal disease research, pediatric cataracts have received comparatively less attention. Dr. Rossen hopes her work will help address that gap and encourage broader recognition of the role genetics can play in pediatric eye care.
The creation of a centralized resource may also support collaboration among ophthalmologists, geneticists, pediatricians, and other specialists involved in caring for children with inherited conditions.
What this could mean for children and families
For families, a cataract diagnosis can raise many questions about a child's future vision and overall health. Research that improves access to genetic information has the potential to provide clearer answers and more targeted care pathways.
As genetic testing becomes more accessible, clinicians may be better positioned to move beyond treating the visible eye condition and identify the underlying causes driving it. Earlier recognition of associated diseases can open the door to interventions that improve both ocular and systemic outcomes.
The study reflects a growing shift toward precision medicine, where understanding the genetic basis of disease helps guide screening, treatment, and long-term care. For children with cataracts, that approach could make an important difference in both vision and overall health.
