Stem cell treatment of eye diseases
Of all the senses, vision is perhaps the most significant for a person, with the help of it there is a perception of the world around us and ourselves in it, because about 2/3 of the information about the external space we receive through visual analyzers. Of course, the visual system is not limited to the eye itself or the visual analyzer – this is the entire chain of the peripheral part of the organ of vision.
All information that falls into the field of view of the apparatus of the eyeball is transmitted through the visual pathways (optic nerve and tract, optic nerve intersection) in stages to the external geniculate bodies (subcortical zones of vision). And then to the key visual center, located in the occipital lobes of the brain (information transfer is carried out by visual radiance, the visual beam of Graziole is also involved in this procedure).
If we describe the structure of the eye in a simplified version, then we can say that the main place in the orbit belongs to the eyeball, and the orbit itself serves as a reliable bone frame that protects and protects the fragile elements of the visual system. Also, to protect the organ of vision, a layer of fatty tissue is placed between the eyeball and the orbit, which takes on shock-absorbing functions, and nerve endings, vessels and muscles pass through this fatty tissue.
Considering the complex and delicate structure of the human visual system, it is not at all surprising that there are many ophthalmic diseases that affect various elements of the eye system. The simplest diseases include simple barley, which is dangerous with purulent inflammatory processes in the edge of the century, but most often passes without significant complications. More complex diseases include myopia, diabetic retinopathy, corneal ulcers and other disorders that cannot be cured without professional medical help.
In the case of ophthalmic diseases, as well as with others, early detection of abnormalities and timely treatment plays an important role; in such cases, most diseases can be stopped quite quickly, without allowing physiological changes in the organs of vision. Therefore, at the first signs of visual impairment, pain in the optic nerve and a feeling of blurred image, you should definitely visit an ophthalmologist. In some cases, simple eye exercises are sufficient. But with some painful lesions of the optic organ, more radical methods of treatment cannot be avoided. To date, the effectiveness of the use of stem cells in the treatment of ophthalmic diseases has been proven. In practice, the treatment of diabetic retinopathy and other ophthalmic diseases is successfully carried out with the help of stem cells.
Treatment of eye diseases with stem cells
Among the most dangerous ophthalmic diseases are glaucoma, macular degeneration, tapetoretinal abiotrophy and other tapetoretinal dystrophies. The worst thing is that the destructive effect of diabetes is capable of destroying photoreceptors and neurons located in the retina; the natural restoration of these structures does not occur, and in such people, vision is not restored, but disappears forever.
Therefore, in such situations, stem cells are a life-giving source, because they are able to recreate the deformed retina of the eye – this is a sensational and almost magical opportunity that has already been applied in practice. The implanted stem cells move to the damaged area and are soldered to the tissue, after which they differentiate into healthy eye cells of the required type. In traumatic eye injuries, modern scientists use stem cells to activate regenerative processes in the retina.
To increase the success of treatment in many ophthalmic diseases (astigmatism, tapetoretinal dystrophies, optic atrophy and tapetoretinal degenerations) stem cells are implanted directly into the eye.
Thanks to long-term research and laboratory tests, today official medicine treats with stem cells such eye diseases:
- Eye burns
- Tapetoretinal dystrophy
- Eye injury
- Atrophy of the optic nerves.
But, unfortunately, despite the rapid development of medicine, such visual impairments as glaucoma and cataracts are still not curable by the implantation of stem cells.
It is worth noting that in the field of treatment of ophthalmic diseases today, both autogenous stem cells (taken directly from the patient) and allogeneic (fetal) cells that produce various biologically active substances are actively used, in turn, such substances activate the restoration of deformed tissues and cells. and also debug the natural process of tissue and cellular homeostasis.
Of course, in some ophthalmic diseases there is no urgent need to resort to cell therapy, however, after eye burns or with recurrent corneal erosion, standard treatment often does not lead to the desired results. And later, the closure of the epithelial damage results in irreversible changes in the cornea. Therefore, in these cases, stem cell transplantation is not only desirable, but also necessary, because their introduction into the body leads to a decrease in corneal turbidity, stimulation of reparative recovery processes, suspension of outflow and normalization of blood flow in the conjunctiva.
A positive effect from the introduction of stem cells is given by such elements contained in them as cytokines, interleukins and growth factors, it is their presence that activates regenerative processes and supports the vital activity of cells in tissues. The procedure for transplanting stem cells to a patient is incredibly simple – no surgical intervention is required – a simple lens can be used to fix the graft and as the cell carrier base.
