Macular Degeneration: Causes, Symptoms, Treatments

Macular degeneration is a disease of the eye, which causes the loss of eyesight in the center field of vision. The disease affects the retina, a layer at the back of the eyeball responsible for clear vision. 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 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.

A person with muscular dystrophy finds it very hard to read, write, recognize faces, and drive. This ailment has mostly been seen in aged people over 50 years and is a common cause of blindness in them.

Macular degeneration is the primary cause of vision impairment worldwide, causing blindness in adults of age 50 and older. The people who are not completely blind are living with low visions and some blindness. According to a theory, almost 14 to 20% of adults from 60 to 80 might have early-stage macular degeneration.
