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.

Age-related decline in eye is common among people in their 60s or older. Some eye problems such as presbyopia and cataracts are quite normal, while more serious age-related eye diseases such as glaucoma, macular degeneration and diabetic retinopathy may affect old people’s daily lives.
