New Treatment Options for Macular Degeneration Give Hope to Patients
Macular degeneration, also known as age-related macular degeneration (AMD), is the deterioration of the macula that results in impaired central vision. AMD is the number one cause of blindness in people over the age of 55. Factors that increase the chance of having macular degeneration include age, Northern European heritage and smoking.
Dry AMD, when the retina and layer underneath it become thin, is the most common type of macular degeneration. This usually progresses slowly and visual deterioration is usually milder in this form. Wet AMD affects 10% of people with macular degeneration and is more severe. In wet AMD, abnormal blood vessels develop and leak fluid and blood into the retina causing scarring and loss of central vision.
