Age Related Macular Degeneration (ARMD)

AMRD is the degeneration and slow cell death of the macula, a very small central area of the retina that is responsible for fine detailed vision necessary for activities such as reading and driving. The main symptom of ARMD is the loss of central vision. Peripheral vision is usually left in tact.

The actual cause of ARMD is unknown, but it is definitely related to age. It is usually detected in people over 65 years old. The main risk factors in its development include family history, blue eyes, high blood pressure, cardiovascular disease, and smoking.

There are two types of ARMD:

  • Dry ARMD is the most common and is present in 90% of cases. It results in a very slowly progressive degeneration of the retina in the macular region. Most people with this disease are urged to take certain vitamins and minerals to slow its progression.
  • Wet ARMD occurs in 10% of cases and it much more devastating to the central vision. In this form of macular degeneration, abnormal blood vessels grow underneath the retina and leak blood and fluid which if left untreated will eventually cause total loss of central vision. Treatment options include laser and more recently the injection of mediations into the vitreous cavity which cause the abnormal blood vessel to regress.
