![]() ![]() Floaters can appear as different shapes, such as little dots, circles, lines, clouds or cobwebs. What you see are the shadows they cast on the retina, the layer of cells lining the back of the eye that senses light and allows you to see. While these objects look like they are in front of your eye, they are actually floating inside it. Floaters are actually tiny clumps of cells or material inside the vitreous, the clear gel-like fluid that fills the inside of your eye. You can often see them when looking at a plain background, like a blank wall or blue sky. You may sometimes see small specks or clouds moving in your field of vision. Treatment consists of extensive lasers called panretinal photocoagulation (PRP), supplemented by shots of medication in the eye. Treatment is mandatory to preserve vision. The new vessels are fragile and are often accompanied by leakage fluid, bleeding, and scar tissue formation that may cause wrinkling or detachment of the retina. ![]() Unfortunately, the new abnormal blood vessels do not re-supply the retina with normal blood flow. The retina responds by growing new blood vessels in an attempt to supply blood to the area where the original vessels closed. The main cause of PDR is widespread closure of retinal blood vessels, preventing adequate blood flow. PDR is present when abnormal new vessels (neovascularization) begin growing on the surface of the retina or optic nerve.Sometimes shots are given in the eye to dry up the macula. When the swelling occurs within the center of the macula (the central area that gives sharp vision), laser treatment is necessary to help dry up the fluid. Many people with diabetes have mild NPDR, which usually does not affect their vision. The leaking fluid causes the retina to swell or to form deposits called exudates. In this stage, tiny blood vessels within the retina leak blood or fluid. NPDR, commonly known as background retinopathy, is an early stage of diabetic retinopathy.Wet AMD occurs when abnormal blood vessels develop and leak blood and fluid under the macula, causing damage that leads to rapid loss of central vision. Wet AMD affects only 10 percent of AMD patients, but it is responsible for 90 percent of all severe vision loss from the disease. A common early sign of dry AMD is the formation of yellow deposits, called drusen, under the macula.ĭry AMD can sometimes turn into wet AMD. It usually develops slowly, so people may not notice any change in their vision right away. Dry AMD affects about 90 percent of patients with AMD. There are two kinds of AMD:”dry” and”wet”. Although people rarely go totally blind from the disease, AMD can make it difficult to read, write, drive or perform other normal daily tasks. AMD does not affect peripheral, or side vision. ![]() It occurs when there is damage to the macula, the part of the eye that allows you to see fine detail. AMD is a serious disease that may result in loss of central vision. ![]()
