Age-related macular degeneration (AMD) is an eye disorder that slowly damages central vision and makes it difficult to read and visualize fine details. The disease is more common in people over 60 years old, the origin is not known, but there is an important genetic basis.

Treatment: No treatment can restore vision to 100%, but a combination of certain vitamins, antioxidants, and zinc can prevent the disease from getting worse. Recommended supplements are: a) 500 milligrams (mg) of vitamin C b) 400 international units of beta-carotene c) 80 (mg) of zinc d) 2 (mg) of copper. Lutein and zeaxanthin, which are substances found in green leafy vegetables, can also lower the risk of macular degeneration. Other therapies are 1) Laser photocoagulation surgery. 2) Photodynamic therapy: a light activates a drug that is injected into the body to destroy leaky blood vessels. 3) Special medicines that prevent the formation of new blood vessels are injected into the eye, called antiangiogenic.
