Annual Eye Exams
Glaucoma is a group of eye disorders that lead to progressive damage to the nerve that connects the eye to the brain called the optic nerve. People with glaucoma can lose nerve tissue, resulting in vision loss.
The optic nerve is a bundle of about 1 million individual nerve fibers that transmits the visual signals from the eye to the brain. In the most common form of glaucoma, primary open-angle glaucoma, the fluid pressure inside the eye increases. This increase in pressure may cause progressive damage to the optic nerve and loss of nerve fibers. Advanced glaucoma may even lead to blindness.
Not everyone with high eye pressure will develop glaucoma, and some people with normal eye pressure will develop glaucoma. When the pressure inside a person’s eye is too high for a particular optic nerve, whatever that pressure measurement may be, glaucoma will develop.
Glaucoma is the second-leading cause of blindness in the U.S. It most often occurs in people over age 40, although an infant (congenital) form of glaucoma exists. People with a family history of glaucoma, African Americans over the age of 40 and Hispanics over the age of 60 have an increased risk of developing glaucoma. Other risk factors include thinner corneas, chronic eye inflammation and taking medications that increase the pressure in the eyes.
The most common form of glaucoma, primary open-angle glaucoma, develops slowly and usually without any symptoms. Many people are not aware they have the condition until they have significant vision loss. Initially, glaucoma affects peripheral or side vision, but it can advance to central vision loss. If left untreated, glaucoma can lead to significant vision loss in both eyes, and may even lead to blindness.
A less common type of glaucoma, acute angle-closure glaucoma, usually occurs abruptly due to a rapid increase of pressure in the eye. Its symptoms may include severe eye pain, nausea, redness in the eye, seeing halos or colored rings around lights and blurred vision. This is an emergency condition in which severe vision loss can occur quickly; see your optometrist immediately.
Glaucoma cannot currently be prevented. But if it is diagnosed and treated early, it can usually be controlled. Medication or surgery can slow or prevent further vision loss.
However, vision already lost to glaucoma cannot be restored. That is why the American Optometric Association recommends an annual dilated eye examination for people at risk for glaucoma. Depending on your specific condition, your doctor may recommend more frequent examinations.
Symptoms and Diagnosis of AMD
In its early stages, the following signs of macular degeneration can go unnoticed.
- Gradual loss of ability to see objects clearly.
- Shape of objects appears distorted.
- Straight lines look wavy or crooked.
- Loss of clear color vision.
- A dark or empty area in the center of vision.
If you experience any of the above signs or symptoms, contact your doctor of optometry immediately for a comprehensive eye examination. Your optometrist will perform a variety of tests to determine if you have macular degeneration or any other eye health problems.
Central vision that is lost to macular degeneration cannot be restored. However, low-vision devices, such as telescopic and microscopic lenses, can maximize existing vision.
Treatment of AMD
With “dry” macular degeneration, the tissue of the macula gradually becomes thin and stops working properly. There is no cure for dry AMD, and any loss in central vision cannot be restored.
However, researchers and doctors believe there is a link between nutrition and the progression of dry AMD. Making dietary changes and taking nutritional supplements can slow vision loss.
Less common, “wet” macular degeneration occurs when fluids leak from newly formed blood vessels under the macula. This leakage blurs central vision. Vision loss can be rapid and severe.
If detected early, wet AMD can be treated with intraocular injections of anti-VEGF medications.
Researchers have linked eye-friendly nutrients such as lutein and zeaxanthin, vitamin C, vitamin E and zinc to reducing the risk of certain eye diseases, including macular degeneration. For more information on the importance of good nutrition and eye health, please see the diet and nutrition section.
Dry Eye Treatment
Dry eye is a condition in which a person doesn’t have enough quality tears to lubricate and nourish the eye. Tears are necessary for maintaining the health of the front surface of the eye and for providing clear vision. Dry eye is a common and often chronic problem, particularly in older adults.
With each blink of the eyelids, tears spread across the front surface of the eye, known as the cornea. Tears provide lubrication, reduce the risk of eye infection, wash away foreign matter in the eye and keep the surface of the eyes smooth and clear. Excess tears in the eyes flow into small drainage ducts in the inner corners of the eyelids, which drain into the back of the nose. Dry eyes can occur when tear production and drainage is not in balance.
People with dry eyes either do not produce enough tears or their tears are of a poor quality:
- Inadequate amount of tears. Tears are produced by several glands in and around the eyelids. Tear production tends to diminish with age, with various medical conditions or as a side effect of certain medicines. Environmental conditions, such as wind and dry climates, can also decrease tear volume due to increased tear evaporation. When the normal amount of tear production decreases or tears evaporate too quickly from the eyes, symptoms of dry eye can develop.
- Poor quality of tears. Tears are made up of three layers: oil, water and mucus. Each component protects and nourishes the front surface of the eye. A smooth oil layer helps prevent evaporation of the water layer, while the mucin layer spreads the tears evenly over the surface of the eye. If the tears evaporate too quickly or do not spread evenly over the cornea due to deficiencies with any of the three tear layers, dry eye symptoms can develop.The most common form of dry eyes occurs when the water layer of tears is inadequate. This condition, called keratoconjunctivitis sicca (KCS), is also referred to as dry eye syndrome.
People with dry eyes may experience irritated, gritty, scratchy or burning eyes; a feeling of something in their eyes; excess watering; and blurred vision. Advanced dry eyes may damage the front surface of the eye and impair vision.
Treatments for dry eyes aim to restore or maintain the normal amount of tears in the eye to minimize dryness and related discomfort and to maintain eye health.
Dry eyes can be a chronic condition, but your optometrist can prescribe treatment to keep your eyes healthy and comfortable and to prevent your vision from being affected.
The primary approaches used to manage and treat dry eyes include adding tears using over-the-counter artificial tear solutions, conserving tears, increasing tear production, and treating the inflammation of the eyelids or eye surface that contributes to the dry eyes.
- Adding tears. Mild cases of dry eyes can often be managed using over-the-counter artificial tear solutions. These can be used as often as needed to supplement natural tear production. Preservative-free artificial tear solutions are recommended because they contain fewer additives, which can further irritate the eyes.
People with dry eyes that don’t respond to artificial tears alone will need to take additional steps to treat their dry eyes.
- Conserving tears. Keeping natural tears in the eyes longer can reduce the symptoms of dry eyes. This can be done by blocking the tear ducts through which the tears normally drain. The tear ducts can be blocked with tiny silicone or gel-like plugs that can be removed, if needed. Or a surgical procedure can permanently close the tear ducts. In either case, the goal is to keep the available tears in the eye longer to reduce problems related to dry eyes.
- Increasing tear production. Your optometrist can prescribe eye drops that increase tear production. Taking an omega-3 fatty acid nutritional supplement may also help.
- Treating the contributing eyelid or ocular surface inflammation. Your optometrist might recommend prescription eye drops or ointments, warm compresses and lid massage, or eyelid cleaners to help decrease inflammation around the surface of the eyes.
You can take the following steps to reduce symptoms of dry eyes:
- Remember to blink regularly when reading or staring at a computer screen for long periods of time.
- Increase the humidity in the air at work and at home.
- Wear sunglasses outdoors, particularly those with wraparound frames, to reduce exposure to drying winds and the sun.
- Nutritional supplements containing essential fatty acids may help decrease dry eye symptoms in some people. Ask your optometrist if taking dietary supplements could help your dry eye problems.
- Avoiding becoming dehydrated by drinking plenty of water (8 to 10 glasses) each day.
Contact Lenses & Fittings
Contact lenses prescribed by a licensed doctor of optometry are worn safely and comfortably by millions of people worldwide and have a long history of providing wearers with a safe and effective form of vision correction. While contact lenses provide many vision benefits, they are not risk-free. Your doctor of optometry can help you better understand how to get the full benefits of your contact lenses and reduce your chances of developing problems.
Protect your eye and vision health with proper hygiene
Contact lens-related eye infections and other injuries can lead to long-lasting damage but often are preventable. Clean and safe handling of contact lenses is one of the easiest and most important measures patients can take to protect their vision. Hygiene is the most critical aspect of successful long-term contact lens wear.
Many common care mistakes, including failing to clean and store lenses as directed by a doctor of optometry and sleeping while wearing contacts, can increase the chance of getting bacteria in the eyes and causing infection. Serious eye infections can lead to blindness and affect up to one out of every 500 contact lens users per year, and even minor infections can be painful and disrupt day-to-day life.
A contact lens is a medical device that requires a prescription
All contact lenses, even purely cosmetic ones, are considered medical devices and require a prescription. If contact lenses are right for you, your doctor of optometry will provide you with the lenses, lens care kits, individual instructions for wear and care and follow-up visits over a specified time.
Contact lens prescriptions generally expire on a yearly basis, unless otherwise determined by your doctor of optometry. Prescriptions for contact lenses and glasses may be similar, but are not interchangeable. Also, different contact lenses often are made from different materials and in different sizes, some of which can be comfortable and healthy for you to wear, while others can lead to discomfort and even eye health problems.
A prescription for contact lenses therefore involves more than simply knowing the optical power that corrects for nearsightedness, farsightedness, or astigmatism.
