Equip families in your care with the resources they need to navigate a CVI diagnosis. A timely diagnosis is the gateway to life-changing services for kids with CVI.
Kids with CVI Can’t Wait
CVI is a research priority for NEI/NIH
- “The condition [CVI] has historically been under-recognized.” –NEI Strategic Plan: Vision for the Future
- “CVI is a big condition, and patients come with a spectrum of issues they deal with. It’s not realistic to have a one-size-fits-all approach. We need better evidence-based tools and guidelines to do a better job of diagnosing, classifying the disease, and also managing the disease.” – Dr. Michael Chiang
- “The way forward for CVI requires collaboration, innovation, and awareness building. Collaboration between vision care providers, neurologists, neuroscientists, patients, parents, educators, rehabilitation specialists, researchers, industry, and NIH institutes. Scientific innovation that includes big data, data sharing, and establishing standard data representation.” -Dr. Michael Chiang
