Macular Degeneration
Overview
Age-related macular degeneration (AMD) is an eye disease that affects the macula, the small central part of the retina responsible for sharp, detailed vision. You use your macula to read, drive, recognize faces, and see fine details.
AMD is a leading cause of vision loss in adults over 50. It does not cause complete blindness, because side (peripheral) vision usually remains, but it can make everyday tasks difficult. Early detection, healthy habits, and prompt treatment of the wet form can help protect your vision. At Bespoke Eye Care in Chester Springs, we monitor retinal health closely and refer quickly when treatment is needed.
Symptoms
Early AMD often causes no symptoms, which is why regular eye exams matter.
Dry AMD
The most common form. Small yellow deposits called drusen build up under the retina and the macula slowly thins. Changes are usually gradual and may include:
- Blurry or dim central vision.
- Needing brighter light for reading.
- Difficulty adapting to low light.
- Reduced contrast and faded colors.
Late dry AMD, called geographic atrophy, can cause a blind spot in central vision.
Wet AMD
Less common but more serious. Abnormal blood vessels grow under the retina and leak fluid or blood, which can cause faster vision loss:
- Straight lines appearing wavy or bent.
- A dark or empty spot in the center of your vision.
- Rapid changes in central vision.
- Difficulty recognizing faces.
Causes & Risk Factors
AMD involves age-related changes beneath and within the retina. Genetics, oxidative stress, inflammation, and abnormal blood vessel growth can contribute depending on the form and stage.
Who is at risk?
You may be at higher risk if you:
- Are over age 50, with risk increasing as you get older.
- Smoke. Smoking is the most important risk factor you can change.
- Have a family history of AMD.
- Have high blood pressure or cardiovascular disease.
- Are of European descent.
- Have a diet low in leafy greens and other nutrient-rich foods.
Why it matters
Advanced AMD can cause permanent central vision loss, making reading, driving, and recognizing faces difficult. Low vision rehabilitation can help people maintain independence.
Diagnosis
AMD is diagnosed during a comprehensive eye exam. At Bespoke Eye Care, we use modern imaging to detect early changes and monitor them over time.
- Dilated retinal exam: Examining the macula for drusen and other changes.
- Optical Coherence Tomography (OCT): Detailed scans of the retina's layers to detect thinning or fluid.
- Retinal photography: Images to compare changes over time.
- Amsler grid testing: A simple grid that helps detect distortion in central vision.
- Visual acuity testing: Measuring how clearly you see.
Treatment & Management
There is no cure for AMD, but treatment and healthy habits can slow progression and protect vision.
Dry AMD Management
- AREDS2 vitamins: For people with intermediate or advanced AMD, this specific supplement formula may lower the risk of progression. Ask us whether it is right for you.
- Healthy habits: Don't smoke, eat leafy greens and fish, stay active, and manage blood pressure.
- UV protection: Wear sunglasses outdoors.
- Home monitoring: Check each eye daily with an Amsler grid.
Wet AMD Treatment
We refer wet AMD urgently to a retina specialist. The main treatment is:
- Anti-VEGF injections: Medication injected into the eye to stop abnormal vessel growth and leakage. Many patients maintain or improve vision with ongoing treatment.
Living With AMD
Low vision aids, magnifiers, and good lighting can make daily tasks easier. We continue to monitor your eyes and coordinate care with your retina specialist.
