Age-Related Macular Degeneration
What Optometrists Can Do for Age-Related Macular Degeneration
We look for early signs of macular degeneration during your comprehensive eye exam, even before you notice any vision changes. Using advanced imaging and a dilated exam, we can spot tiny deposits called drusen or changes in the macula that may suggest AMD. Small drusen can be a normal part of aging, and an AMD diagnosis depends on the size and pattern of drusen, macular pigmentary changes, and other clinical features.
Catching AMD in its earliest stages allows us to recommend protective steps that may slow its progression. Regular eye exams are especially important if you are over 50, have a family history of AMD, or have other risk factors.
Once we detect AMD, we will schedule follow-up visits to track any changes in your macula. These monitoring appointments help us see whether the disease is staying stable, progressing slowly, or converting from dry to wet AMD.
We use specialized imaging tests at each visit to compare your macula to previous exams. If we see any worrisome changes, we can act quickly to adjust your care plan or refer you to a specialist.
For patients with intermediate AMD or advanced AMD in one eye, we may recommend a specific formula of vitamins and minerals based on the AREDS2 research study. This supplement includes vitamin C, vitamin E, zinc, copper, lutein, and zeaxanthin. It has not been shown to help early AMD or to restore vision that has already been lost.
Taking AREDS2 vitamins daily can reduce your risk of AMD progression by about 25 percent in certain stages of the disease. We will let you know if this supplement is right for you and help you find a brand that meets the correct formula.
If AMD has affected your central vision, we can fit you with low vision devices such as magnifiers, special reading glasses, or electronic aids. These tools help you continue everyday activities like reading the newspaper, using your phone, or enjoying hobbies.
We also connect you with low vision rehabilitation services that teach strategies for making the most of your remaining vision. Our goal is to help you maintain independence and quality of life despite vision loss.
When we detect wet AMD or significant worsening of your condition, we refer you to a retina specialist, also called an ophthalmologist who focuses on diseases of the retina. These doctors perform treatments such as anti-VEGF injections that can help control wet AMD and protect vision.
We work closely with retina specialists to make sure you get timely appointments and the right level of care. Early referral is important because treatment works best when started promptly.
Even when you see a retina specialist for injections or other procedures, we continue to monitor your overall eye health and manage any other conditions you may have. This team approach ensures continuity of care.
We stay in regular contact with your retina specialist, sharing test results and updates. You benefit from both our comprehensive primary eye care and the specialized expertise of the ophthalmologist.
Understanding Age-Related Macular Degeneration
The macula is a small area at the center of your retina responsible for sharp, detailed central vision. In AMD, this delicate tissue begins to break down due to aging, genetics, and other factors.
As the macula deteriorates, you lose the crisp central vision you need for tasks like reading, driving, and recognizing faces. Your side vision usually remains intact, so you can still move around safely.
Dry AMD is the most common form and develops slowly when yellowish deposits called drusen build up under the macula. Over time, the macula may thin and lose function, leading to gradual central vision loss.
Wet AMD is less common but more serious. It occurs when abnormal blood vessels grow under the macula and leak fluid or blood, causing rapid and severe vision loss. Wet AMD can develop suddenly, sometimes in someone who already has dry AMD, though it can also occur without a known prior diagnosis of dry AMD.
Early AMD often causes no symptoms at all, which is why regular eye exams are so important. As the disease progresses, you may notice that straight lines appear wavy, colors seem less bright, or you need more light to read.
- Blurry or fuzzy central vision
- Dark or empty spots in the center of your vision
- Difficulty recognizing faces
- Trouble reading or doing close work
- Straight lines that look bent or distorted
Certain symptoms suggest that dry AMD may be converting to wet AMD, which requires urgent evaluation. If you notice a sudden increase in blurriness, new distortion of straight lines, or a dark spot that appears quickly in your central vision, contact us the same day or within 24 hours.
Prompt evaluation is important because delays can reduce the chance of the best outcome. We will arrange for you to see a retina specialist right away if we suspect wet AMD.
Age is the biggest risk factor, with most cases occurring in people over 60. You are also at higher risk if you have a family history of AMD, smoke cigarettes, have high blood pressure, or are overweight.
- Being over age 50
- Having a parent or sibling with AMD
- Smoking or a history of smoking
- Being of Caucasian or European descent
- Having cardiovascular disease or high cholesterol
How We Diagnose Age-Related Macular Degeneration
We start by putting drops in your eyes to widen your pupils, allowing us to see the back of your eye clearly. Once your pupils are dilated, we use a special lens and bright light to examine your macula for signs of drusen, pigment changes, or abnormal blood vessels.
The dilation process takes about 20 to 30 minutes, and your vision may be blurry for a few hours afterward. We recommend bringing sunglasses and arranging a ride home if you are not comfortable driving with dilated eyes.
OCT is a painless, non-invasive scan that creates detailed cross-section images of your macula. This technology lets us see the layers of your retina and measure thickness, helping us detect early AMD and monitor changes over time.
The scan takes only a few minutes and feels similar to having your photograph taken. We often use OCT during your visits to compare your current macula to prior scans and catch any progression early.
The Amsler grid is a simple chart with a pattern of straight lines and a dot in the center. During your exam, we ask you to look at the dot and tell us if any lines appear wavy, broken, or missing.
We also give you an Amsler grid to use at home. Checking the grid regularly with each eye, often daily for higher-risk eyes, lets you spot new distortion or blank areas quickly, which may signal that dry AMD is converting to wet AMD. We will guide you on how often to check based on your individual risk.
If we suspect wet AMD or need more detailed information about blood vessels in your retina, we may refer you for fluorescein angiography. This test involves injecting a special dye into your arm and taking photographs as it travels through the blood vessels in your eye. You may experience temporary skin and urine discoloration and occasional nausea, which are normal. Allergic reactions are rare but can occur. If you experience trouble breathing, hives, or swelling, seek urgent care immediately.
Other advanced imaging techniques, such as OCT angiography, can show blood flow in the retina without injections. These tests help retina specialists plan the best treatment for wet AMD or other complications.
Treatment Options for Age-Related Macular Degeneration
The AREDS2 supplement is the only proven nutritional therapy shown to slow progression of intermediate and advanced dry AMD. We may recommend this formula when your disease has reached a stage where it is likely to benefit from extra antioxidants and minerals. It is most helpful for patients with intermediate AMD or advanced AMD in one eye, where the fellow eye is at risk. AREDS2 has not been shown to help early AMD or to restore vision that has already been lost.
- Vitamin C 500 milligrams
- Vitamin E 400 international units
- Zinc 80 milligrams and copper 2 milligrams
- Lutein 10 milligrams and zeaxanthin 2 milligrams
Because the formula contains high doses of antioxidants and minerals, discuss it with your primary care clinician or pharmacist if you take blood thinners, have liver disease, or take other supplements. The vitamins can interact with certain medications and conditions.
Wet AMD is treated with injections of anti-VEGF medications directly into the eye. These drugs block a protein that causes abnormal blood vessels to grow and leak. They often slow or stop further vision loss and may improve vision in some patients, especially when treatment is started early.
Injections are performed by retina specialists in an office setting using numbing drops. Most patients need injections often monthly at first, then the schedule is adjusted based on how your macula responds. Some regimens and newer medications allow for longer intervals between injections.
After your injection, you may notice mild irritation, tearing, or a foreign-body sensation for a short time. These are common and usually resolve within a day or two. However, you should seek urgent care if you experience worsening pain, increasing redness, rapidly decreasing vision, new dense floaters, severe light sensitivity, eye discharge, or a severe headache. Serious complications are rare but can include infection, retinal tear or detachment, bleeding inside the eye, or a spike in eye pressure.
- Mild irritation, tearing, or foreign-body sensation is common and temporary
- Worsening pain or increasing redness requires urgent evaluation
- Rapidly decreasing vision or new dense floaters should be reported immediately
- Severe light sensitivity, discharge, or headache may signal a complication
- Rare serious risks include infection, retinal tear, bleeding, and pressure spikes
Laser photocoagulation was once used for wet AMD but has largely been replaced by anti-VEGF injections, which preserve vision better. In rare cases, your retina specialist may consider laser for specific types of abnormal vessels away from the center of the macula.
Photodynamic therapy, which combines a light-sensitive drug with a special laser, is also used less often now but may be considered in specific cases when anti-VEGF alone is not enough.
Geographic atrophy is an advanced form of dry AMD in which areas of the macula progressively thin and lose function. There are now approved intravitreal treatments aimed at slowing the growth of atrophy in geographic atrophy, though they do not restore vision that has already been lost. Your retina specialist can help determine if you are a candidate.
- Approved geographic atrophy treatments are given by injection into the eye
- These treatments aim to slow the enlargement of atrophic areas, not reverse damage
- Potential risks include an increased chance of conversion to wet AMD
- Ongoing monitoring is essential to watch for new blood vessel growth
- Additional therapies are in clinical trials, including longer-acting drugs, implantable devices, gene therapies, and treatments targeting novel pathways
If you are interested in learning about clinical trials for newer treatments, we can discuss whether you might be a candidate. Participating in research can give you access to investigational therapies while helping advance care for future patients.
We refer you to a retina specialist if we detect wet AMD, rapid worsening of dry AMD, geographic atrophy that may benefit from treatment, or any complications that require advanced care. These ophthalmologists have extra training in diseases of the retina and perform procedures we cannot do in our office.
Getting to a specialist promptly is essential for wet AMD because treatment is most effective when started early. We coordinate your referral and make sure your records are sent ahead of your appointment.
Managing Your Vision and Eye Health with AMD
We will give you an Amsler grid to keep at home and check regularly. Test each eye separately in good lighting, wearing your reading glasses if you use them. For higher-risk eyes, we often recommend daily checks, but we will guide you on the best schedule for your situation.
If you notice any new wavy lines, blank spots, or other changes, call our office immediately. Catching a conversion to wet AMD early can make a big difference in preserving your vision.
A diet rich in dark leafy greens like spinach and kale, fatty fish such as salmon, and colorful fruits and vegetables may help protect your macula. These foods provide antioxidants and omega-3 fatty acids that support retinal health.
- Spinach, kale, and collard greens
- Salmon, tuna, and other fatty fish
- Oranges, berries, and other colorful fruits
- Nuts and legumes for healthy fats
Ultraviolet light from the sun may contribute to AMD progression, so we recommend wearing sunglasses that block 100 percent of UVA and UVB rays whenever you are outdoors. A wide-brimmed hat provides extra protection.
Some patients find that lenses with blue light filters reduce glare and eye strain during computer use or other screen time. Current evidence does not show that blue light filtering prevents AMD progression, but these lenses are safe and may help with visual comfort if you have symptoms related to screen use.
Smoking is the single most important modifiable risk factor for AMD. If you smoke, quitting can significantly reduce your risk of developing AMD or slow its progression if you already have it. We can connect you with resources to help you quit.
Managing your blood pressure, cholesterol, and overall cardiovascular health is also important. Regular exercise and maintaining a healthy weight may help protect your eyes and reduce your risk of AMD progression.
- Quit smoking or avoid starting to reduce your AMD risk
- Control high blood pressure and cholesterol with medication and lifestyle changes
- Engage in regular physical activity most days of the week
- Maintain a healthy weight through balanced diet and exercise
If AMD has reduced your central vision, specialized devices can help you maintain independence. Handheld magnifiers, stand magnifiers, and electronic video magnifiers enlarge text and images so you can read labels, recipes, and books.
We fit you with the right magnification and teach you how to use these tools effectively. Many patients also benefit from large-print materials, talking watches, and high-contrast labeling in the kitchen.
The frequency of your follow-up visits depends on the severity and type of AMD you have. Patients with early dry AMD may need exams every six to twelve months, while those with intermediate or advanced disease typically come in every three to six months. Your individual schedule may vary based on symptoms and other risk features.
If you are receiving anti-VEGF injections for wet AMD, your retina specialist will see you as often as every four weeks, though schedules vary. We coordinate with your specialist to continue monitoring your overall eye health between injection visits.
Frequently Asked Questions
Currently, there is no cure for AMD, and vision loss from advanced dry AMD cannot be reversed. However, anti-VEGF injections for wet AMD can stop further damage and sometimes improve vision if started early. Approved treatments for geographic atrophy aim to slow progression but do not restore lost vision. Researchers are working on new therapies that may one day restore vision or halt the disease entirely.
AMD affects only your central vision, not your peripheral side vision, so it typically does not cause total blindness. However, it can cause legal blindness and significant disability that affects reading, driving, and face recognition. Most people with advanced AMD can still navigate their homes, see large objects, and maintain some level of independence with the help of low vision aids and rehabilitation.
AREDS2 vitamins are most beneficial for patients with intermediate AMD or advanced AMD in one eye. If you have only small drusen and no other significant risk factors, the supplements may not provide meaningful benefit. We will review your specific exam findings and discuss whether the vitamins are right for you.
Injection schedules vary from person to person and depend on how your macula responds to treatment. Many patients start with monthly injections and then move to longer intervals such as every six to eight weeks. Some newer medications and treatment regimens allow for even less frequent visits while still controlling the disease.
Whether you can drive safely depends on how much AMD has affected your central vision and whether you meet your state's vision requirements for a driver's license. We can perform a vision test and discuss your driving safety. Some patients with mild AMD continue driving during the day, while others need to limit or stop driving as the disease progresses.
