Macular degeneration significantly affects your central vision, making tasks like reading and recognizing faces challenging. At our practice, we specialize in comprehensive care for this condition and are committed to helping you maintain your vision health.
Macular degeneration is an eye condition that affects the central part of your vision by damaging the macula, a small yet critical area in the retina responsible for seeing fine detail. It is especially common in people over the age of 50, though it can sometimes affect younger individuals due to various risk factors. While macular degeneration does not lead to complete blindness, it significantly impairs your ability to see directly in front of you, impacting tasks such as reading and recognizing faces.
Macular degeneration is an age-related eye disease that primarily impacts the macula—the central portion of the retina that handles detailed vision. In untreated macular degeneration, the macula gradually deteriorates, making tasks like reading, driving, or recognizing loved ones more challenging. Although peripheral vision remains largely unaffected, the loss of central vision can change everyday activities in a meaningful way.
There are two main forms of macular degeneration that patients should be aware of: dry and wet. Each type differs in terms of progression, severity, and the level of impact on central vision.
Dry (Atrophic) Macular Degeneration
Nearly 90% of those affected have the dry form. It is characterized by the gradual buildup of tiny yellow deposits known as drusen under the macula. Over time, the macula thins out and dries, leading to a slow, progressive loss of central vision. Although vision loss happens gradually, this form can sometimes advance to the more severe wet type.
Wet (Exudative) Macular Degeneration
This type is less common, affecting about 10% of patients, but it is the more severe variant. It occurs when abnormal blood vessels form beneath the retina and start leaking fluid and blood. This leakage causes a bulge or distortion of the macula, leading to dark or blank spots in central vision. The wet type can cause rapid vision loss if not promptly managed.
The dry type of macular degeneration is often described in three stages, each marking a progression in the deterioration of central vision:
At this point, some changes occur in the macula, but they rarely affect vision noticeably. Regular eye exams are key to detecting these early signs.
Vision may begin to appear wavy or blurry. Patients might notice minor distortions in straight lines or slight color changes, indicating further macular deterioration.
Central vision becomes significantly compromised. Although peripheral vision continues to work well, daily activities that rely on sharp central focus become increasingly difficult.
Wet macular degeneration, by definition, is an advanced stage of the disease and therefore should be addressed promptly by our retina specialists to preserve as much vision as possible.
Macular degeneration is not solely a consequence of aging; several other factors can contribute to its development. While the exact cause of the macula's degeneration often remains unclear, both inherited and environmental elements play a role. Here’s a look at some of the main contributors:
Being over 50 is the most significant risk factor for macular degeneration, which is why the condition is often referred to as age-related macular degeneration (AMD).
A family history of macular degeneration increases your likelihood of developing the condition.
Tobacco use is a well-known risk factor, as it may contribute to the damage of the central retina over time.
Diets high in saturated fats, along with being overweight, can negatively affect retinal health.
High blood pressure is linked to a higher risk of developing AMD.
Certain genetic variations may predispose individuals to both dry and wet forms of the disease.
Conditions such as diabetes or past eye injuries can increase the risk of developing macular degeneration.
Understanding these risk factors empowers you to make lifestyle changes that could help protect your vision over time.
Macular degeneration can be challenging to detect in its early stages because it often does not produce noticeable symptoms initially. However, as the condition progresses, you may experience the following signs:
Distorted Vision
Straight lines might appear wavy or bent, an early red flag that your central vision is being affected.
Blurred Central Vision
Reading text, recognizing faces, or seeing fine details becomes difficult.
Dark or Blotchy Spots
These can appear in the center of your vision and may expand as the disease worsens.
Difficulty in Low Light
Your ability to see clearly in dimly lit environments might be reduced.
Color Changes
There could be subtle shifts or migrations in how you perceive colors.
If you notice that straight lines suddenly appear distorted or if you experience any other changes in your central vision, it is wise to contact our retina specialists promptly. Early detection can allow for timely interventions that may slow the condition’s progression.
Since macular degeneration often develops without early symptoms, regular eye examinations are crucial, especially if you have risk factors or a family history of the condition. Our retina specialists employ several diagnostic tools that examine the retina and macula in detail:
You might be given a grid with a central dot and asked to report any areas where the lines appear blurry, wavy, or broken. This simple at-home test can help monitor changes in your vision over time.
Special eye drops widen your pupils, allowing the specialist to use a high-powered lens to closely inspect the back of your eye.
In this test, a yellow dye is injected into your arm, which travels to the blood vessels in your eye. A specialized camera then takes images that reveal any leakage under the macula.
This non-invasive imaging test creates detailed cross-sectional images of your retina and macula. It helps identify any thinning or swelling in these vital areas.
OCTA uses laser light reflection to provide 3D images of blood flow within the retina, offering a quick and detailed look at the health of your blood vessels.
These diagnostic techniques allow for a comprehensive evaluation of your eye’s health. Regular check-ups are one of the best ways to catch macular degeneration early and determine the most effective course of action.
Dry macular degeneration, which accounts for about 90% of cases, tends to progress gradually. One of the main strategies for managing the dry form is nutritional supplementation.
The Age-Related Eye Disease Studies (AREDS and AREDS2) have shown that a specific blend of vitamins and minerals can help slow the progression of dry AMD. Key ingredients include:
It is noteworthy that the earlier version of these supplements contained beta-carotene, which has been replaced in newer formulas with zeaxanthin and lutein due to health concerns for smokers.
These nutritional supplements are used to support overall retinal health and potentially slow down the progression of the disease. While they may not reverse vision loss, they can help manage symptoms over time.
Wet macular degeneration requires a different treatment approach because of its rapid progression:
Medications that counteract vascular endothelial growth factor (VEGF) are critical in halting the formation of abnormal blood vessels. Our retina specialists may administer these injections directly into the vitreous after numbing the eye. The treatment can sometimes improve vision by stopping or reducing fluid leakage. Common medications include Aflibercept, Ranibizumab, Bevacizumab, Faricimab, and Brolucizumab.
This treatment involves an injectable light-sensitive drug, which is then activated by a laser to target and destroy the abnormal blood vessels beneath the macula without causing significant damage to surrounding tissues.
One of the earliest treatments for wet AMD, this method employs a focused laser beam to seal off leaking blood vessels. Although its use has diminished with the advent of anti-VEGF injections, it can still be useful in certain cases.
Each treatment option carries potential side effects and risks such as eye infections, retinal detachment, or even the progression of cataracts. Our retina specialists will discuss these factors with you to determine the most suitable plan that balances benefits and risks.
The primary impact of macular degeneration is the loss of central vision, which can affect reading, facial recognition, and activities that rely on focused sight.
Changes in vision can sometimes lead to feelings of isolation, depression, or anxiety. It is important to address these feelings and seek support if needed, as emotional well-being is a key part of managing any chronic condition.
Some individuals with significant vision loss may experience visual hallucinations. Although these hallucinations are not linked to mental illness, they can be unsettling without proper understanding and management.

Options like anti-VEGF injections or photodynamic therapy may carry risks such as eye infections, retinal detachment, or other structural damage that could further impact vision.
While some risk factors, such as age and genetics, are beyond our control, there are several lifestyle choices that can help lower your risk of developing or worsening macular degeneration.
Smoking has been linked to an increased risk of macular degeneration. Stopping smoking can not only promote better eye health but also improve overall well-being.
Embracing a diet rich in leafy greens, fruits, and fish—similar to the Mediterranean diet—can provide essential nutrients that benefit your eyes. Staying away from high levels of saturated fats can also be beneficial.
Regular physical activity and a balanced diet help keep your weight in check, reducing the chances of developing related conditions like high blood pressure and diabetes.
Keeping these in comfortable ranges can support vascular health in the eyes.
Incorporating these steps into your lifestyle not only benefits your vision but also contributes to your overall health. It’s a proactive way to manage your risk and safeguard your quality of life.
Adjusting to changes in your vision can be an emotional journey. Coping with macular degeneration involves understanding the condition and adapting your daily routines to focus on what you can see clearly. Even if central vision declines, there are many strategies and tools you can use to help maintain independence and confidence.
Tools like magnifying devices, brighter lighting solutions, or specialized eyeglasses can support you in tasks such as reading and using a computer.
Small adjustments at home, like using high-contrast colors for important objects and labeling items clearly, can help you navigate your environment more easily.
Connect with support groups or counselors who understand the challenges you face. Sharing experiences can foster a sense of community and reduce feelings of isolation.
Even though macular degeneration leads to a gradual loss of central vision, many people find ways to continue enjoying their hobbies and maintaining a full life with appropriate support and adaptive strategies. Our retina specialists encourage you to remain proactive and involved in your care plan.
