Artificial eyes and optic nerves

In summary: Glaucoma is a condition in which damage to the optic nerve causes loss of vision. It is the most common cause of legal blindness in the United States. In people with glaucoma, the optic nerve is damaged by increased pressure inside the eye. This can happen because of a problem with the drainage system in the eye, called glaucoma, or because of a problem with the way the eye’s lens works. In summary, millions of people have Glaucoma and are about to lose the sight to Glaucoma or just generally the blind. There are many different types of artificial eyes, but

There are millions of Glaucoma patients who lost or about to lose the sight to Glaucoma or just generally the blind which numbers in millions too. I know a person who has Glaucoma.

I just want to know what is the status with artificial eyes and growing optic nerves at present and forthcoming. The visual cortex is at the back of brain. When will we have the technology so the blind can see (even coarse resolution) by directly connecting some optics nerves and retina sensors at the back of the head (by knowledge of some minimum language of the brain and interfacing to neurons in the visual cortex)? That is. If the front is far, then eyes at back of head won't be bad than having nothing to see.

I suspect that there is far more effort being put into preventing blindness and the effort is certainly paying off, the outcome for people with Glaucoma is largely dependent on early and effective treatment. In people currently diagnosed with glaucoma less than 5% will go totally blind and this could still improve.
Developing artificial vision is horribly complex but even there the device mentioned by Tom.G seems to have been developed further with electrodes being attached directly to the visual cortex, the results seem better than the retinal implants. While the brain does seem to attempt to make sense of the signals it receives, the results are very limited and in both cases the surgery carries significant risk. In devices that have an external port there is a significant infection risk that increases over time. In the case of the electrodes to the visual cortex they are only allowed to leave it in place for 6 months.
Personally I think that the greatest possibilities come from the development of biological therapies that lead to repair of the structures involved.

For those with glaucoma, how many pieces of optics nerves remaining before they could still make out objects in the world and what resolution is it like equal to?

Glaucoma is really defined by the damage to the optic nerve the relationship between this and the intra occular pressure is still unclear, its not really a single condition. I'm not sure its possible to quantify the amount of damage other than by looking at the loss of vision which commonly starts at the periphery of the visual field, this can lead to an effect almost like looking down a tunnel.
This is a useful site with lots of links, one specifically about the latest research which is interesting.

1. What are artificial eyes and optic nerves?

Artificial eyes and optic nerves are man-made devices that serve as replacements for natural eyes and optic nerves. They are designed to mimic the function of the human eye and optic nerve in order to restore vision to individuals who have lost their sight due to injury or disease.

2. How do artificial eyes and optic nerves work?

Artificial eyes and optic nerves work by using advanced technology to capture and process visual information, which is then transmitted to the brain via the optic nerve. They often incorporate miniature cameras, sensors, and microchips to simulate the function of the retina and optic nerve.

3. Who can benefit from artificial eyes and optic nerves?

Artificial eyes and optic nerves can benefit individuals who have lost their vision due to conditions such as glaucoma, retinal degeneration, or traumatic eye injuries. They can also be used to improve vision in individuals with certain types of visual impairments or disorders.

4. Are there any risks or side effects associated with artificial eyes and optic nerves?

As with any medical procedure, there are potential risks and side effects associated with artificial eyes and optic nerves. These may include infection, discomfort, or rejection of the device by the body. It is important to consult with a qualified medical professional before undergoing any procedures involving artificial eyes and optic nerves.

5. What is the future of artificial eyes and optic nerves?

The field of artificial eyes and optic nerves is constantly evolving, with new technologies and advancements being made regularly. Researchers are working on developing more advanced and realistic devices that can provide better vision and functionality for individuals with visual impairments. It is likely that we will see significant advancements in this field in the near future.
