The blood vessels formed under and into the macular portion of the retina are very fragile and often leak blood and fluid. Macula provides the ability to see fine details and is responsible for central vision. In wet age-related macular degeneration (AMD), abnormal blood vessels, also known as choroidal neovascularization (CNV), start to grow in the macula, which is a small portion of the retina located in the central area of the retina. For example, a person with wet degeneration, when he looks at a clock, will be able to see the sides of the clock, including numbers but might not be able to see the mid area of needles. This blind spot can be black, grey, or even red.
The blurred vision can include a blind spot in the center field of vision. At the start, the person with macular degeneration notices blurred and distorted vision. The individual might feel problems with his eyesight. Wet macular degeneration can appear suddenly with no symptoms of pain. Macular degeneration is classified into two types.Īpproximately 85 to 90% of the cases of macular degeneration are of Dry while almost 10 to 15% population seems to have a wet type. According to a theory, almost 14 to 20% of adults from 60 to 80 might have early-stage macular degeneration. The people who are not completely blind are living with low visions and some blindness. Macular degeneration is the primary cause of vision impairment worldwide, causing blindness in adults of age 50 and older. This ailment has mostly been seen in aged people over 50 years and is a common cause of blindness in them. The central portion of the retina is known as the macula, and it is responsible for focusing the central vision of the eyes when it deteriorates, the images start to become blurry and dark spots can appear, which get bigger over time, but the person will not get completely blind.Ī person with muscular dystrophy finds it very hard to read, write, recognize faces, and drive. The role of the retina is to record the images that the human eye sees, and then it sends it through the optic nerve to the brain from the eye. The disease affects the retina, a layer at the back of the eyeball responsible for clear vision. Macular degeneration is a disease of the eye, which causes the loss of eyesight in the center field of vision.
