Macular degeneration is an eye disease that causes vision loss in the centre of the visual field. The disease affects the retina, the layer responsible for clear vision at the rear of the eyeball. The retina’s function is to record the images seen by the human eye, which it then transmits to the brain via the optic nerve. The macula is the portion of the retina responsible for focusing the central vision of the eyes; when it deteriorates, images become blurry and dark patches appear, which grow larger over time, but the individual does not go completely blind.
It is very difficult for a person with muscular dystrophy to read, write, recognise faces, and drive. This condition is a prevalent cause of blindness in people over the age of 50.
Macular degeneration is the leading cause of vision impairment in the globe, resulting in blindness in adults aged 50 and older. People who are not completely blind have impaired vision and varying degrees of blindness. A hypothesis suggests that between 14 and 20 percent of adults aged 60 to 80 may have early-stage macular degeneration.
