Age-related macular degeneration, often called ARMD or AMD, is the leading cause of vision loss among Americans 65 and older.
AMD causes damage to the macula, which is the central portion of the retina responsible for sharp central vision. AMD doesn't lead to complete blindness because peripheral vision is still intact, but the loss of central vision can interfere with simple everyday activities such as reading and driving, and it can be very debilitating.
Types of Macular Degeneration
There are two types of macular degeneration: Dry AMD and Wet AMD.
Dry (non-exudative) macular degeneration constitutes approximately 85-90% of all cases of AMD. Dry AMD results from thinning of the macula or the deposition of yellow pigment known as drusen in the macula. There may be gradual loss of central vision with dry AMD, but it is usually not as severe as wet AMD vision loss. However, dry AMD can slowly progress to late-stage geographic atrophy, which can cause severe vision...

Remember back to the last time you experienced the birth of a baby. What was one of the most common questions people asked? Most likely, "WHAT COLOR ARE HIS EYES?,” was right up there.
What makes the color of our eyes appear as they do? What role do genetics play? What if you don’t like your eye color--can you change it? Are there any medications that can change the eye color? Get ready to explore the science behind eye color by starting at the beginning.......
Baby’s eye color can change. A baby can start out with blue eyes, for example, that change to brown as she ages. It’s all dependent on a brown pigment called melanin which develops as a child grows. The more melanin present, the darker the eye color. Brown eyes have the most pigment saturation, green/hazel eyes have less melanin, and blue eyes have the least pigment. The color of eyes is dependent upon genetics. Genetics are complicated, but generally speaking brown trumps blue if there is a brown-eyed parent. This is...
