This technology is a key step toward personalized eye care.
Use Cases
- Personalized Gene Therapy for Specific Mutations: Retinitis Pigmentosa is caused by over 50 known gene mutations. Gene therapy is now helping to target some of these defects. One example is the treatment for the RPE65 gene mutation. This therapy works by delivering a healthy copy of the gene into the retina. It can slow down vision loss and improve clarity, especially when started in early childhood. Personalized gene therapy offers new hope to patients who previously had no options. As genetic testing becomes more accessible, more people can benefit from targeted treatments. These therapies are designed for long-term impact and are changing how RP is managed.
- Retinal Implants for Late-Stage Patients: In the advanced stages of Retinitis Pigmentosa, most patients lose almost all usable vision. Retinal implants are helping to restore basic visual function. These electronic devices are implanted in the eye and allow users to detect light and simple shapes. This can help with daily activities like moving around or identifying objects. While vision is not fully restored, even minimal improvement boosts independence. Patients with implants often report better mobility and reduced need for assistance. These technologies continue to improve and are becoming a realistic option for late-stage RP care. Their role in vision restoration is steadily expanding.
- Vitamin A Supplementation in Early Stages: Vitamin A, especially in the form of palmitate, has long been used for early-stage Retinitis Pigmentosa.
