The Macula of Retinaabsorbs excess blue light and ultraviolet light
The Gula fläcken ( Macula of retina ) is a small, yellow spot located in the posterior pole of the eye. It contains the largest concentration of cone cells in the retina. The macula absorbs excess blue light and ultraviolet light, acting as a protective sun block for the retina. Generally, it is about nine millimeters in diameter.
Researchers believe that the lack of vasculature in the macula could contribute to its high photoreceptor cell density. During the aging process, photoreceptor cells in the macular region are more vulnerable to degeneration and damage. In addition, the inner retina of the macula is thin and avascular. This could lead to compromised photoreceptor cells.
While many parts of the retina are vital to vision, the macula is particularly important for the processing of central vision. Images from the macula are transmitted to the brain via the optic nerve, which then processes them. In general, the macula is responsible for central vision, while the remainder of the retina is responsible for peripheral vision. This region of the retina gives us clear, fine-detailed vision that we rely on for reading, driving, and recognizing people.
If you have a macular hole, your vision will suffer, and you may not be able to see properly. It may cause distorted or blurred vision and may make it difficult to read small print. It may also appear as a small black patch. In most cases, age-related macular degeneration does not lead to total loss of sight, but it can lead to blindness.
A macular hole may be caused by many different things. Besides aging, previous eye surgery, sun exposure, or ocular trauma are all possible causes. Some symptoms you may experience include blurry central vision, a patch of blurry vision, or image distortion. A self-exam called the Amsler grid may be helpful to determine if you have a macular hole. If you suspect it, you should visit a physician for a thorough examination.
Macula degeneration is a condition that causes problems with central vision and has a variety of symptoms as well as treatment options. The macula experiences a slow but steady loss of cells, which ultimately leads to the disease. There is another name for this ailment, which is dry age-related macular degeneration. Sadly, there is currently no treatment available for this illness.
Surgery: If a macular hole is not severe, surgery can be done to repair it. This procedure can improve vision. However, there are risks involved, such as a detached retina. This is the most common treatment for this condition. During the procedure, vitreous gel is removed. The hole is then filled with a mixture of air and gas to seal the hole. Another treatment option is membrane peel, which removes scar tissue.
Diagnosis: Angiography or OCT is a simple test for age-related macular degeneration. The former involves injecting a dye into the arm. A photographer takes pictures as the dye flows through the blood vessels of the macula. Photos taken during the procedure will reveal leaky vessels and new blood vessels. If detected early, laser treatment can prevent the disease from progressing or affecting central vision.
