![]() This condition is called Charles Bonnet syndrome. With profound loss of vision, people may see visual hallucinations. People whose dry macular degeneration has progressed to central vision loss have a higher risk of depression and social isolation. If you have heart or blood vessel disease, you may be at higher risk of macular degeneration. Research indicates that being obese may increase your chance that early or intermediate macular degeneration will progress to the more severe form of the disease. Smoking cigarettes or being regularly exposed to tobacco smoke greatly increases your risk of macular degeneration. Macular degeneration is more common in white people. Researchers have identified several genes linked to the condition. ![]() This disease is most common in people over 60. Risk factorsįactors that may increase your risk of macular degeneration include: Over time, tissue in the macula may thin and lose cells responsible for vision. The macula is the area of the retina that's responsible for clear vision in the direct line of sight. Dry macular degeneration affects the macula. Research indicates that it may be a combination of family genes and environmental factors, including smoking, obesity and diet. No one knows exactly what causes dry macular degeneration. Cones give the eye color vision, and rods let the eye see shades of gray. The macula is made up of densely packed light-sensitive cells called cones and rods. A healthy macula allows for clear central vision. The macula is located at the back of the eye in the center of the retina. These changes may be the first sign of macular degeneration, particularly if you're over age 60.
