Macular Degeneration

Macular degeneration, which is also called age-related macular degeneration or AMD, affects more than 2 million Americans and is the leading cause of vision loss in seniors.1 The highly experienced retina specialists at Retina Vitreous Associates are experts in diagnosing and treating AMD.

Understanding Macular Degeneration or AMD

Your retina is a sensory membrane at the back of your eye that processes light into images. The macula is a part of the retina that is responsible for clear, crisp detail in your central vision. Macular Degeneration causes the macula to deteriorate, resulting in central vision loss when looking straight ahead. AMD is a progressive disease, which means that there may be no noticeable symptoms in the beginning, but patients may gradually experience a loss of clear vision. There is no cure for AMD, but your retina specialist can provide treatment to minimize vision loss. Early detection is very important for successful management of AMD.

Types of AMD

AMD is categorized into two types:

Dry Macular Degeneration

Non-exudative macular degeneration, commonly referred to as dry macular degeneration, accounts for approximately 90% of AMD cases.2 Dry AMD is caused by a thinning of the macula and a growth of protein clumps called drusen. Symptoms of dry AMD tend to be very gradual.

Wet Macular Degeneration

Exudative macular degeneration, or wet AMD, is not as common as dry AMD, and it is typically more severe. Wet AMD is caused by abnormal blood vessel growth under the retina. These newly formed blood vessels may leak and cause scarring. Vision loss as a result of wet AMD typically occurs faster than it does with dry AMD.

AMD Symptoms

Symptoms of AMD may include:

Patients with dry macular degeneration may experience such a slow progression of symptoms that they find themselves trying to adapt to changes in vision.

How is AMD Diagnosed?

Since AMD symptoms are often gradual, it is very important to have yearly comprehensive eye exams. A dilated eye exam is the best way to detect changes in the retina and the macula. If your eye doctor suspects that you may have AMD, our retina specialists can use special diagnostic tools to determine the type and severity of your AMD:

Fluorescein Angiogram

A small amount of special dye is injected into your bloodstream in order to photograph the flow of blood through your retina. This can show any abnormal blood vessel growth or leakage, which would indicate wet AMD.

Optical Coherence Tomography (OCT)

Scans are taken of your eye to produce detailed, high-resolution images of your retina. This test can show us if there is any abnormal fluid accumulation or swelling in your eye.

What Treatments Are Available For AMD?

While there is no cure available for AMD, there are treatment options that aim to preserve your vision. Studies show that antioxidant vitamins and minerals can reduce the vision damage caused by dry AMD. Our retina specialists can discuss which nutritional supplements may be effective in preventing vision loss from AMD.

For patients with wet macular degeneration, our eye doctors can administer medications such as Avastin®, Lucentis®, and Eylea® to halt the growth and in cases reverse the damage from these vessels.
