Can You Restore Your Vision Back After Glaucoma?

Glaucoma is among some of the common eye disorders that lead to blindness in several people. Talking about this disease, it leads to vision loss because the optic nerve gets damaged and is no longer available to transfer the information to the brain. The axons present in the optic nerve are unable to process the information due to the damaged condition. This medical condition is treated by lowering the blood pressure levels in the eye with the help of certain medications and drugs. Often, surgery can also be used.

With the help of these treatments, you can only preserve the remaining vision in the eye. They are unable to restore the already lost vision due to glaucoma. Traditional and laser surgeries can help restore the vision left.

Is Blindness In Glaucoma Permanent?

Talking about the nervous system, it is divided into peripheral and central nervous systems. When talking about the peripheral muscles, they can be regenerated. One of the common examples of these is damaged muscles in the arms that can be regenerated. When talking about the body parts like the spinal cord and optic nerve, they come under the control of the central nervous system. Therefore, they cannot be regenerated after the injury.

Restore Your Vision Back After Glaucoma

This is the main reason why the injuries caused to the spinal cord and optic nerve lead to permanent damage. Cases of paralysis of the spinal cord cannot be reversed. The cellular environment of the central nervous system is unique and allows the cells to be moved in a certain direction only. This is why regeneration is prevented in such cases.

What are the regeneration strategies?

To get the vision restored, several regeneration strategies can be adopted. One of the common strategies to enhance nerve fiber growth is the elimination of inhibitory factors in the cellular environment. The studies conducted have helped to know that by preventing the expression of molecules suppressing the axon growth with the help of some molecular biology techniques. A good example of this can be the introduction of antibodies for blocking the inhibition and allowing the nerve fibers to regrow.

Some of the other common strategies that may be used for regeneration are:

Nanotechnology: This technique involves creating the protein nanofiber structures that help the axons to regenerate themselves.

Nerve Grafts: This method has been tried on some individuals. When the optic nerve gets damaged, it starts responding with the help of scar tissue. The nerve fibers have not been regenerated through the nerve tissues.

Cellular Implants: Well, these are some of the engineered cells that provide physical support to the neuronal fibers. Also, they help in promoting the chemicals to help in axonal growth. These have a significant role in initiating the regeneration process.

Promoters of nerve growth: The nerve growth promoters like oxyntomodulin have shown a great impact in the process of regeneration.

Genetic manipulations: Genetic manipulations help in stimulating optic nerve regeneration. However, much more research is required in this field.

Stem cell approaches: The stem cell approaches have been effective and help in regeneration in models of glaucoma. Multipotent stem cells are retrieved from tissues like bone marrow and fat. It helps in avoiding ethical concerns.

Could there be any future approaches?

Many types of research have been done in this field that has helped in better understanding of the concepts. The specialists performing studies have focused on the process of optic nerve degeneration and regeneration in glaucoma. They have been able to identify several molecular factors that promote nerve fiber growth in your central nervous system. New technologies like nanotechnology, stem cell, and gene therapy have been significant and effective in bringing advancement to the field of medicine. Some of the major challenges ahead are optimization of nerve regeneration and testing if it restores functionally meaningful levels of vision for glaucoma patients.

Conclusion

Well, there is no perfect treatment for glaucoma and the doctors can only revive the vision that is left. However, some prompt treatment can aid in the slowing or stopping of the progression of vision loss. Depending on the severity of the case, the treatment can include certain medications or any surgery directed towards lowering blood pressure levels.
