What are the different types of retinal diseases?
responsible for sending important codes to the brain to process visual images, the retina at the back of the eye and contains specialized photoreceptor cells. Cells are called cones and rods and form a complex retina tissue. There are many retina diseases that can prevent how one sees and processes visual information. The main types of retinal disease are diabetic retinopathy, macular degeneration related to age, retinal separation, eye cancer and inherited retinal degeneration. These disorders may lead to partial or full blindness.
Diabetic retinopathy (DR) is one of the main causes of blindness. It is the result of complications of diabetes, type 1 or 2. When the blood sugar level is uncontrolled, its blood vessel blood vessels may damage. This type of retinal disease is often not detected, but it can be prevented if one manages blood sugar and goes to planned annual eye tests.
One of the most common retinous AL that causesLoss of vision in people aged 65 and older, is macular degeneration related to age. This disease causes the loss of central vision and leaves only peripheral vision intact. Supplied in two forms: wet or non -presented; and dry or neovascular. Wet macular degeneration leads to a new growth of blood vessels in parts of the eye that should not have blood vessels. Dry macular degeneration is caused by thinning and aging of macular tissues and usually leads to yellow spots around the macula of the person.
The retina disconnection is when the retina is separated from choroids, a layer of blood vessels that supply nutrients and oxygen to the retina. When this disease occurs, the eye does not receive the necessary oxygen. This can lead to permanent loss of vision, but early detection and treatment can prevent this disease.
Other types of Diseases retina include eye cancer such as retinoblastoma and eye melanoma. RetinoblAstom usually affects children and cancer in the retina. This happens when the nerve cells of the retina have genetic mutations that cause to grow cells of cells called a tumor, inside the eye. Eye melanoma is similar to skin cancer and develops in cells producing melanin in the eye. This disease is sometimes difficult to find out because it does not have many early symptoms or symptoms.
Some people inherit retina disease from their family gene fund. An example of this type of disease is retinitis pigmentosa, which damages the retina and leads to incurable blindness. The first symptoms of this retina disease usually include decreased vision during the night or in poor light and loss of peripheral vision. Other inherited retinal diseases include Cone-Rod, Retinoschesis and Usher's syndrome.
