Stargardt disease is the most common form of inherited juvenile macular degeneration. The progressive vision loss associated with Stargardt disease is caused by the death of photoreceptor cells in the central portion of the retina called the macula.
The retina is the delicate light-sensing tissue lining the back inside wall of the eye. Photoreceptor cells in the retina provide vision by conveying information from the visual field to the brain. The macula is responsible for sharp central vision for tasks like reading, watching television, and looking at faces.
Age-related macular degeneration (AMD) is a deterioration or breakdown of the eye’s macula. The macula is a small area in the retina the light-sensitive tissue lining the back of the eye. The macula is the part of the retina that is responsible for your central vision, allowing you to see fine details clearly.
Glaucoma is a group of eye diseases that gradually steal sight without warning. In the early stages of the disease, there may be no symptoms. Experts estimate that half of the people affected by glaucoma may not know they have it.
Vision loss is caused by damage to the optic nerve. This nerve acts like an electric cable with over a million wires. It is responsible for carrying images from the eye to the brain.
What is Retinitis Pigmentosa?
Retinitis Pigmentosa (RP) is the name given to a group of degenerative diseases
of the retina. The retina, at the back of the eye, is a thin sheet of interconnected
nerve cells including the light sensitive cells (rods). It is here that light
is converted into electrical signals to the brain where "seeing" takes
In RP the rod and cone cells degenerate. Depending on the type of RP, the rate
of progression varies.
