Stem cell treatment for macular degeneration
Adult Stem Cell’s therapy is aimed at more than 80 percent of macular degeneration patients who have the dry form of the disorder. In some patients, the disease progresses to the more serious “wet” form, which can cause almost complete vision loss. Stem cell treatment for macular degeneration patients can slow or reverse their vision loss and prevent blindness.
Vision loss is any reduction in the ability to see, including blurred vision, cloudy vision, double vision, blind spots, poor night vision, and loss of peripheral vision (tunnel vision). Vision loss may affect one or both eyes, it may occur gradually or suddenly, and it may be partial or complete. Vision changes may originate in the eyes themselves or may be caused by many different conditions that affect the brain or even the whole body.
The path of light rays, which form all the images we perceive, begins at the cornea, the clear “window” in the front of the eye. The iris, which is the colored part of the eye, controls the pupil size and allows light rays to enter the eye and pass through the lens. This helps to focus the rays onto the retina, which is the light-sensitive layer on the inner surface of the eye. Damage caused by trauma, infection, inflammation, or other changes in these structures can reduce vision. The shape of the eye is maintained by the pressure of the fluid inside the eye against the sclera, the white part of the eye, and the cornea. Conditions that affect the clarity or pressure of the fluid in the eye can also affect vision.
The optic nerve collects information from the retina and transmits it to the brain for interpretation. Damage to the nerve due to inflammation, autoimmune disease, or decreased blood supply can lead to vision loss, as can conditions that affect the brain either generally or in the specific locations of the brain that interpret vision.
Some common causes of vision loss include eye trauma, clouding of the lens (cataract), increased eye pressure (glaucoma), retinal damage due to diabetes (diabetic retinopathy), breakdown of the central portion of the retina (age-related macular degeneration), retinal detachment, inflammation of the optic nerve (optic neuritis), and stroke. Some medications can also affect vision.
