The majority of macular degeneration cases occur in older people, so that the terms of macular degeneration and age-related macular degeneration are usually used interchangeably. In fact, macular degeneration can also be caused by certain drugs, including Aralen, Mellaril, Prolixin, Trilafon and Stelazine. But all forms of macular degeneration involve gradual or sudden central vision loss. Early symptoms of AMD can be waved straight lines, fuzzy vision and shadowy areas in the central vision.

A large European study revealed that the combination of too few antioxidants in diet and exposure to blue light (HEV) rays can significantly increase the risk of developing advanced macular degeneration. Blue light alone is never linked with any kind of macular degeneration. However, low consumption of antioxidants such as vitamin C and zinc can make blue light rays more harmful. Besides taking more nutrients from vegetables and fruits, older people should also get HEV protection from proper sunglasses.

Macular degeneration and cataracts are mostly found in old adults and may cause impaired vision or even blindness. Regular eye exams play an important role in detecting early vision problems, which in turn suggests appropriate treatments. There are still many ways in maintaining good eye health, such as lifestyle changes, proper UV protection, smoking quitting and so on. Another helpful method is to take eye beneficial nutrients, both from diet and supplements.

As hardened fats, trans-unsaturated fats are associated with heart diseases because they can raise levels of bad cholesterol and lower levels of good cholesterol. However, higher amounts of trans-unsaturated fats are also reported to increase the risk of age-related macular degeneration, according to the Archives of Ophthalmology. Lots of trans-unsaturated fats intake is suspected to be closely related with late AMD.

Macular degeneration, glaucoma or other eye diseases may damage your macula or the optic nerve, which may lead to vision loss. Early detection and treatment are crucial to minimize the risk. One of the convenient devices for potential macular degeneration discovery is the Amsler grid, although you can not use it as a replacement of regular doctor visits. An Amsler grid comprises of a center black dot and many horizontal and vertical lines.

Just as the name reflects, age-related macular degeneration (AMD) has been a severe eye disease among people over 65. The estimated number of AMD affected Americans is 3 million by 2020. As a part of the retina, macula is responsible for sharp and central vision, so that AMD may lead to vision loss.
