Age-Related Macular Degeneration: Symptoms and Treatment

December 22, 2011 by Anne Arundel Eye Center

Age-related macular degeneration (AMD) is the leading cause of vision loss and blindness in Americans 60 years of age or older. Currently, about 1.75 million U.S. residents have advanced AMD with associated vision loss. That number expected to grow to almost 3 million by 2020.

AMD is an eye disease that affects the part of the retina (the macula) responsible for sharp, central vision. As a result, AMD can make it difficult to perform every day tasks, such as reading and driving.

Symptoms of Age-Related Macular Degeneration

Gradual loss of ability to see objects clearly
Objects appear distorted in shape. Straight lines look wavy or crooked.
Loss of clear color vision
A dark or empty area appears in the center of vision.

If you feel you may be experiencing any of the above symptoms, schedule an appointment with your eye doctor as soon as possible. Any sudden change in your vision is a serious medical condition that requires prompt medical attention from your optometrist or ophthalmologist.

AMD can advance so slowly that individuals initially notice little change in their vision. Other times, AMD progresses more rapidly and may even lead to vision loss in both eyes. This is why regular eye exams are so important. They can help detect the eye disease before it causes significant vision loss.

Age-Related Macular Degeneration Treatment

There are two types of AMD, “dry” macular degeneration and the less common “wet” macular degeneration.

Dry AMD: With this form of AMD, the tissue of the macula gradually becomes thinner and stops functioning properly. There is currently no cure for dry AMD and any vision loss associated with the disease cannot be restored, even with treatment.
Wet AMD: This form of AMD is caused by fluid that leak from newly formed blood vessels under the macula, resulting in blurred central vision. With wet AMD, vision loss can be rapid and severe, but if detected early, this form of AMD can be treated with photocoagulation (laser treatment).
Other potential treatment options include:
Anti-angiogenesis drugs: These medications block the development of new blood vessels and leakage from the abnormal vessels within the eye that cause wet macular degeneration.
Vitamins: A recent study found that vitamins C, E, beta carotene, zinc and copper can decrease the risk of vision loss in patients with intermediate to advanced dry macular degeneration.

Photodynamic laser therapy: A two-step treatment in which a light sensitive drug is used to damage the abnormal blood vessels. A doctor injects the drug into the bloodstream to be absorbed by the abnormal blood vessels in the eye. The doctor then shines a cold laser into the eye to activate the drug, damaging the abnormal blood vessels.

While AMD treatment cannot restore your vision, it can help to slow further vision loss.

The Elderly are at an Increased Risk for Eye Disease

October 28, 2011 by Anne Arundel Eye Center

In a statement by National Eye Institute Director Paul A. Sieving, M.D., Ph.D., on World Sight Day 2011, the Director urged older Americans to protect their vision. Because, as Sieving explained, older people are simply at an increased risk for eye diseases, including age-related macular degeneration (AMD), Cataracts, Glaucoma, and Diabetic Retinopathy.

AMD – This eye disease can cause loss of central vision due to the breakdown of the light-sensing cells in the retina.

Cataracts – This eye disease clouds vision because of a clumping of proteins in the eye’s lens.

Glaucoma – This eye disease involves damage to the optic nerve caused by increased intraocular pressure (IOP).

Diabetic Retinopathy – This eye disease impairs vision due to diabetes-related injury to the eye’s blood vessels.

Early stages of these diseases have no symptoms, which is why regular eye exams are crucial to catching eye disease before permanent vision loss occurs. The importance of early detection and treatment of age-related eye disease cannot be overstated.

If you experience a sudden change in vision, such as blurriness/blurry vision, schedule an appointment with your eye doctor immediately. If this change in vision is extreme or if any eye pain is involved, consider having a family member or friend drive you to the emergency room.

Any change in your sight is a serious medical condition that requires immediate attention.

What You Should Know About Diabetic Retinopathy

July 15, 2011 by Anne Arundel Eye Center

Diabetes affects more than 23.6 million people in the United States alone – meaning that 7.8% of the population has the disease. Of these individuals, between 40 to 45 percent have some degree of Diabetic Retinopathy, the most common progressive eye disease resulting from long-term diabetes. Diabetic Retinopathy, which damages to the blood vessels in the eye, is also the leading cause of blindness in American adults.

It is extremely important for those with diabetes to not only seek regular medical care, but also regular eye exams (at least once a year), as well. If caught early enough, Diabetic Retinopathy is very treatable. However, if you wait until you experience symptoms of the disease, it may be too late to reverse the damage, though worsening of Diabetic Retinopathy may be slowed with treatment even in advanced stages of the disease.

Symptoms may include:

Blurred vision
Shadows or loss of areas of vision
Difficulty seeing at nighttime

In the early stages of Diabetic Retinopathy, no symptoms occur, making the disease almost impossible to diagnose without the help of a professional. This is why regular eye exams are so important.

There are two types (stages) of the disease:

Non-proliferative (the first stage): Enlarged blood vessels and fluid/blood leaking into the retina cause problems with eyesight.

Proliferative (advanced): New blood vessels form in the eye and hemorrhage, causing scarring on the retina and other parts of the eye. This results in many problems with sight and can lead to complete vision loss.

While new treatment options are in development as scientists work toward a better understanding of this disease, regular eye exams and early detection remain your best options for fighting Diabetic Retinopathy.
