Overview:
'BIONIC EYE ELECTRODES' are crucial components of visual prosthetics designed to restore vision to individuals who are blind or have severe vision impairments. These devices work by stimulating the retinal cells or the visual cortex directly, depending on the type of bionic eye.
Types of Bionic Eye Electrodes
1. Retinal Implants:
🔹Epiretinal Implants: These are placed on the surface of the retina. They stimulate the retinal ganglion cells directly.
🔹Subretinal Implants: These are placed beneath the retina, specifically targeting the photoreceptor layer.
2. Cortical Implants:
These are implanted directly into the visual cortex of the brain. They bypass the eyes entirely and directly stimulate the brain regions responsible for vision.
3. Suprachoroidal Implants:Positioned in the suprachoroidal space, which is between the sclera and the choroid. They provide a less invasive method compared to other retinal implants.
Current Research and Development:
🔹Improving Resolution: Efforts are ongoing to increase the number of electrodes to improve the resolution of the perceived image.
🔹Longevity and Durability: Research focuses on making the implants more durable and able to function effectively for many years.
🔹Minimizing Invasiveness: Developing less invasive methods of implantation to reduce surgical risks and improve recovery times.
Key consideration:
🔹Biocompatibility: The materials used for electrodes must be biocompatible to avoid adverse reactions within the body.
🔹Resolution and Electrode Density: Higher electrode density can provide better visual resolution, but it also requires more precise and complex technology.
🔹Power Supply: The device needs a reliable power source that is safe and long-lasting.
Function mechanism behind Bionic Eye Electrodes:
🔹Image capture,
🔹Signal Processing,
🔹Electrical Stimulation
Applications:
🔹Retinitis pigmentosa
🔹Age related macular degeneration
🔹Other retinal disorders
Results:
These advancements are paving the way for more effective and accessible bionic eye systems, offering hope to individuals with various forms of blindness.New biocompatible materials reduce the risk of rejection and improve the longevity of the implants. Flexible and conductive materials also enhance the integration with retinal tissue.
