<unk>  is an eye disorder that damages the macula, which is responsible for central vision and is located near the center of the retina. The disease gradually destroys sharp, central vision, thereby making it difficult to see fine details. Because it normally affects older adults, the disorder is also called age related<unk> . According to the American Academy of Ophthalmology, it is the leading cause of central vision loss in the United States today for those over the age of fifty years.
Although<unk>  typically affects older adults, Stargardt’s disease (STGD), also known as Juvenile<unk> , is an autosomal recessive retinal disorder characterized by a juvenile-onset macular dystrophy, alterations of the peripheral retina, and subretinal deposition of lipofuscin-like material.<unk>  occurs in two forms: dry and wet.
Dry<unk>  occurs when the blood vessels under the macula become thin and brittle. Small yellow deposits, called drusen, form under the macula. As these drusen increase in size and number, they create a blurred and dim spot in the central vision of the eye. Almost all people with<unk>  start with the dry form. It has three stages, all of which may occur in one of both eyes:
Early dry<unk> 
Intermediate dry<unk> 
Advanced dry<unk> 
Early dry<unk> 
Intermediate dry<unk> 
Advanced dry<unk> 
Wet<unk>  occurs when abnormal blood vessels behind the retina start to grow under the macula. This is called choroidal neovascularization. These new blood vessels tend to be very fragile and often leak blood and fluid. The blood and fluid raise the macula from its normal place at the back of the eye, which leads to rapid damage of the macula. Although only about 10 percent of people with<unk>  have this form, it causes most of the vision loss associated with the condition. With wet<unk> , loss of central vision can occur quickly, and there are no stages.
All people who have the wet form had the dry form first. Both the wet form and the advanced dry form are considered advanced<unk> , and vision loss occurs with either form.
