Artificial Retina - Science Nation

Kathy, blind for over 30 years due to retinitis pigmentosa, finds hope in an artificial retina developed with NSF support. The device, involving a camera and a chip implanted in the retina, helps her perceive light contrasts. Kathy is one of 20 patients using this technology, which is still evolving. Her journey involves learning to interpret visual signals, akin to a child's developmental stages. The technology promises a future where higher resolution chips could allow users to recognize faces. Kathy hopes this advancement will benefit future generations, including her descendants.

What was Kathy's life like before her diagnosis with retinitis pigmentosa?

• She had just started a new job and was dating her future husband.

• She was struggling with her career.

• She was already blind and adapting to it.

• She was a student in college.

What is retinitis pigmentosa?

• A curable eye disease.

• A genetic disease leading to visual loss.

• A temporary condition affecting vision.

• A disease affecting only the elderly.

What made Kathy a suitable candidate for the artificial retina device?

• She was the only patient willing to try the device.

• Her eye's circuitry was intact despite losing rods and cones.

• She had a different type of eye disease.

• She had partial vision loss due to cataracts.

How does the artificial retina device work?

• It restores vision through medication.

• It uses laser surgery to repair the retina.

• It replaces the entire eye with a robotic one.

• It uses a camera in glasses to send signals to a chip in the retina.

What does Kathy experience when using the device?

• She hears sounds that help her navigate.

• She sees clear, detailed images immediately.

• She sees flashes of light indicating contrast.

• She feels vibrations indicating obstacles.

What is the potential future improvement for the artificial retina device?

• Increasing the chip's resolution to over 1000 pixels.

• Eliminating the need for surgery.

• Making the device wireless.

• Reducing the size of the camera.

What is Kathy's hope for her grandchildren regarding the eye disease?

• That there will be a cure for retinitis pigmentosa.

• That they will inherit her resilience.

• That technology will provide them with some vision if needed.

• That they will never face any vision problems.
