Macular Degeneration Care
Advanced Testing, Personalized Nutritional Support & Lifelong Vision Care
Age-related macular degeneration (AMD) affects the macula—the central portion of the retina responsible for reading, recognizing faces, driving, and seeing fine detail. Although AMD does not typically affect peripheral vision, changes in central vision can significantly impact everyday activities.
At Wyomissing Optometric Center, we take a comprehensive approach to macular degeneration. Our doctors evaluate retinal structure, visual function, nutritional status, and changes over time to create a personalized plan for monitoring, treatment coordination, and vision support.
Understanding Macular Degeneration
The two primary forms of AMD are:
- Dry macular degeneration: The more common form, which may progress gradually as deposits called drusen accumulate and retinal tissue changes over time. Advanced dry AMD may lead to geographic atrophy.
- Wet macular degeneration: A more urgent form caused by abnormal blood vessels that leak fluid or blood beneath the retina. Prompt evaluation and treatment by a retina specialist are essential.
Early AMD may not cause noticeable symptoms. As the condition progresses, patients may experience:
- Blurred or distorted central vision
- Straight lines appearing wavy
- Difficulty reading or recognizing faces
- Reduced contrast or color perception
- A dark, blurry, distorted, or missing area in the center of vision
- Increased difficulty adjusting from bright light to dim lighting
Advanced Retinal Testing
Our doctors use several technologies to evaluate both the structure and function of the retina.
OCT and OCT Angiography
Optical coherence tomography (OCT) produces detailed cross-sectional images of the retinal layers. It can help identify drusen, thinning, atrophy, fluid, and other changes associated with AMD.
OCT angiography (OCT-A) provides a noninvasive view of blood flow within the retina and underlying choroid. It may help identify abnormal blood vessel patterns without the use of an injected dye.
Retinal Photography and Fundus Autofluorescence
Retinal photographs create a visual record that allows our doctors to compare changes over time.
Fundus autofluorescence provides additional information about the health and activity of the retinal pigment epithelium—the supporting layer of cells beneath the retina. This imaging can be particularly helpful when evaluating areas of retinal stress or atrophy.
Dark Adaptometry
Dark adaptometry measures how efficiently the eyes adjust after moving from bright light into darkness. Difficulty adapting to dim lighting may be associated with changes in retinal function that are not fully reflected by standard visual acuity testing.
This information can help us establish a functional baseline, diagnose early AMD, and monitor changes over time.
Electroretinography
When AMD appears to be advancing, or when symptoms and structural findings do not fully correspond,
electroretinography (ERG) may be recommended. ERG objectively measures the retina’s electrical response to light, providing additional information about how well the retinal cells are functioning.
Carotenoid Testing and Retinal Nutrition
Carotenoids such as lutein and zeaxanthin are concentrated within the macula and help support the retina’s natural defenses against oxidative stress and high-energy light.
We offer two methods of carotenoid assessment:
- LifeMeter testing: A quick, noninvasive fingertip measurement that estimates carotenoid levels within the skin and body.
- Macular Pigment Optical Density testing: MPOD testing estimates the density of protective macular pigment within the central retina.
Together, these tests provide a broader picture of nutritional carotenoid status. Results can be used to guide dietary conversations, establish a baseline, and monitor changes following nutritional or supplementation recommendations. Carotenoid testing complements—but does not replace—a comprehensive retinal examination and imaging.
Customized Nutritional Support and Supplementation
Nutritional recommendations should not be one-size-fits-all. Our doctors consider each patient’s:
- Stage and type of macular degeneration
- LifeMeter and MPOD results
- Current diet and supplement use
- Smoking history
- Medications and other health conditions
- Individual risk factors and family history
Recommendations may include increasing foods naturally rich in retinal-supportive nutrients, such as dark leafy vegetables, colorful fruits and vegetables, fish, nuts, and other sources of healthy fats.
For patients who meet the appropriate clinical criteria, an AREDS2-based supplement may be recommended to help reduce the risk of progression to advanced AMD.
These supplements do not cure macular degeneration or restore vision that has already been lost, and they are not appropriate for every patient. We carefully review supplement ingredients, dosage, smoking history, medications, and overall health before making a recommendation
Education and Home Monitoring
Understanding AMD is an important part of protecting vision. We take time to explain test results, review retinal images, discuss modifiable risk factors, and help patients recognize symptoms that require prompt attention.
Home monitoring may include an Amsler grid, ForeseeHome device prescription, or other recommended vision-monitoring tools. Contact an eye doctor promptly if you notice:
- New distortion or wavy lines
- A sudden decrease in central vision
- A new dark, blurry, or missing area
- A noticeable change in the size or shape of objects
- A sudden change in color or contrast perception
Collaborative Retina Care
When treatment or additional evaluation is needed, we coordinate care with retina specialists. This may include referral for wet AMD, geographic atrophy, or significant progression.
Our doctors continue to provide ongoing monitoring, education, nutritional guidance, and supportive care alongside your retina specialist.
Low Vision Support
When macular degeneration affects daily activities, low vision rehabilitation can help patients use their remaining vision more effectively and maintain independence.
Our goal is to help each patient continue participating in the activities that matter most to them.
Protecting Your Vision for the Future
Macular degeneration care involves more than checking visual acuity. Through advanced retinal imaging, functional testing, individualized nutritional assessment, education, specialist collaboration, and low vision support, we provide a comprehensive plan designed around each patient’s needs.
