According to a recent study out of the Wilmer Eye Institute at Johns Hopkins University School of Medicine, nearly 50 percent of people (47.4 percent) of the 2,044 U.S. adults polled rated vision loss as the worst possible health outcome, surpassing such other conditions as loss of limb, memory, hearing, or speech. Top concerns among respondents were a diminishing quality of life ranked followed closely by loss of independence. [Read more…]
Glaucoma: An Overview from Dr. Nathan Frank
According to a survey conducted in 2002 by Prevent Blindness America, 30 percent of Americans have never heard of
glaucoma and only half of those participating in the survey actually knew what it was. Glaucoma is the second leading cause of blindness in the world, and specialists believe that roughly 2.2 million people in America are affected. Only half of these individuals know that they have the disease. Given that January is Glaucoma Awareness Month, this is a great time to review the condition so that you, as patients, can become better informed and more knowledgeable.
Glaucoma is a multi-factorial disease that causes damage to the optic nerve that eventually leads to vision loss. Peripheral (side) vision loss occurs due to damage of the optic nerve of eye, which is similar to a fiber optics cable with about 1.2 million fibers that send images from the eye to the brain. There are two main types of glaucoma: primary open angle glaucoma and angle closure glaucoma. Both are usually marked by increased eye pressure inside the eye, but differ in the anatomical structure of the drainage system of the eye.
Risk factors for glaucoma? Everyone is at risk for glaucoma, newborn babies and senior citizens alike. However, there are several groups of people with an increased risk of developing the disease. Risk is heightened by:
- Race (African Americans, Asians and Hispanics)
- Diabetes
- High blood pressure
- Steroid Use
- Age (People over 60)
- History of eye trauma
- Family History of glaucoma
- High near-sighted patients
What are the common symptoms of glaucoma? The majority of people that have glaucoma are without symptoms. The visual symptoms that do occur tend to occur later in the disease process.
How to diagnose glaucoma? A comprehensive eye evaluation is imperative to rule out any suspicion for glaucoma. There are several important factors that need to be assessed prior to making a diagnosis. These include: measurement of eye pressure (normal range 12-22), a close assessment of the optic nerve, a peripheral visual field measurement, an exam of the drainage system of the eye, and finally a measurement of the cornea of the eye. These measurements are repeated once or twice a year or more often if there is any concern about progression.
How is glaucoma treated? The best way to protect your vision if diagnosed with glaucoma is to continue care
with your eye care provider. The goal of treatment is to lower the intraocular pressure to prevent further damage to the optic nerve. When diagnosed with glaucoma, the first line of treatment usually starts with the use of a single eye drop that is instilled once a night. If further pressure lowering is needed, additional drops can be used. Further treatment options include laser therapy or, if necessary, surgical treatment.
Glaucoma is a very complicated disease and this is only a brief overview. Some questions may still remain; a great
resource for information is glaucoma.org, a website that is constantly updated with information for those with glaucoma and for those who may know others with glaucoma.

Age-Related Macular Degeneration: Symptoms and Treatment
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.

Education on Glaucoma and Cataracts Detection and Treatment
More than 3 million Americans have glaucoma, yet half are unaware that they have it, while cataracts, the leading cause of visual loss in people 65 and older, will affect half of adults by age 80. These are two very different diseases that have one big thing in common; they are both treatable if caught early.
Glaucoma
Glaucoma refers to a group of diseases that can affect your sight without warning and, if left untreated, can lead to blindness.
Everyone is at risk for glaucoma, however, certain factors may increase this risk including: if you are over 60 years of age, if you are African American, if you have high myopia (nearsightedness), diabetes, hypertension, or if you are a steroid user.
The bad news is that there is currently no cure for glaucoma. The good news is that early detection and treatment (medication and surgery) have been proven to slow down or even prevent further vision loss due to glaucoma, which is why regular eye exams are so important.
Cataracts
A cataract, or clouding of the eye’s natural lens, is a disease usually brought on by age – affecting half of adults by age 80. After years of natural wear and tear, the lens becomes clouded, much like a clear plastic window on a convertible car that turns yellow after years of exposure to sun and weather.
Cataracts symptoms include: blurry sight and sometimes double vision; halos and glare—the eyes become dazzled by bright light, making night driving difficult; colors may become faded; and frequent changes in glasses prescription.
Whether you are experiencing symptoms of cataracts or you fear you may have glaucoma, the earlier you are diagnosed by a certified ophthalmologist, the more a doctor will be able to help you without major intervention/surgery. If you feel you may be at risk, schedule an eye appointment right away.
At Anne Arundel Eye Center, a state-of-the-art treatment center offering complete ophthalmic exams as well as diagnostic surgical eye care, the staff works to not only treat you, the patient, but also educate you about your diagnosis.
“When you give people that knowledge and power, it gives them the ability to take part in their care,” Dr. Samuel Boles told What’s Up Magazine “Patients are more likely to comply with their therapy if they know what you’re asking them to do and why you’re asking them to do it. It’s important to me to help my patients understand the importance of taking care of themselves.”
