What You Need to Know About Age-Related Macular Degeneration (AMD)
Understanding Age-Related Macular Degeneration
This section explains how AMD affects the eye and why early detection matters.
AMD damages the macula, the central part of the retina responsible for sharp, detailed vision. As the macula weakens, tasks like reading or recognizing faces become harder.
The macula provides the clarity needed for everyday activities such as driving, using digital devices, and spotting facial expressions. When it fails, peripheral vision stays, but central detail fades.
AMD is usually slow at first, producing few symptoms. Over time, blurred or distorted areas can appear in the center of vision, and the disease can advance to more serious stages if untreated.
Types and Stages of AMD
AMD occurs in two main forms, each with specific stages that influence treatment decisions.
Dry AMD accounts for about 80–90 percent of all cases. It begins with small yellow deposits called drusen beneath the retina and may slowly reduce central vision.
Wet AMD is less common but more severe. Abnormal blood vessels grow under the retina, leak fluid, and cause rapid vision loss. Immediate attention is crucial.
Dry AMD typically moves from early to intermediate and then late geographic atrophy. Wet AMD is always considered advanced because of its rapid damage.
Dry AMD Explained
Most patients first encounter the dry form, so knowing its stages helps with timely care.
At this stage, vision seems normal but drusen are present. Routine eye exams often reveal the condition before symptoms appear.
Subtle vision changes may occur, such as slight blurring or trouble adjusting to low light. Dietary changes and supplements based on the AREDS2 study can slow progression.
Large areas of retinal tissue break down, leading to significant central vision loss. Research continues, but there is no cure yet.
Dry AMD represents the majority of AMD cases. Risk rises sharply with age, affecting nearly half of adults older than 85.
Risk Factors for AMD
Some risk factors cannot be changed, but lifestyle choices can lower overall risk and slow disease progression.
The chance of developing AMD climbs after 40 and increases each decade thereafter.
Having a close relative with AMD raises personal risk. Regular exams help detect early signs when family history is positive.
Smoking, poor diet, obesity, and lack of exercise contribute to AMD development and progression.
Long-term exposure to sunlight may slightly raise AMD risk, so protective eyewear is recommended.
Healthy choices can make a difference.
- Quit smoking to improve blood flow to the retina.
- Eat leafy greens, colorful fruits, and fish rich in omega-3 fats.
- Exercise regularly to support circulation.
- Manage blood pressure and cholesterol.
- Wear sunglasses that block UV rays.
Dry vs Wet AMD Treatments
Treatment goals vary by type and stage, focusing on slowing damage and preserving remaining vision.
Doctors recommend AREDS2-based supplements, balanced nutrition, regular exercise, and smoking cessation. Vision rehabilitation tools, such as magnifiers, help patients adapt.
Wet AMD often requires anti-VEGF injections that slow abnormal vessel growth. Photodynamic therapy or laser treatment may be used in select cases. Ongoing care limits further vision loss.
Diagnosing AMD
Comprehensive eye exams detect AMD early and guide therapy choices.
Eye drops widen the pupil, allowing a clear view of the retina and macula.
A simple grid helps reveal wavy or missing lines, early signals of macular damage.
OCT creates cross-section images of retinal layers, showing fluid buildup or thinning.
A dye highlights retinal blood vessels, helping identify leaks linked to wet AMD.
Living with AMD
A supportive care plan and regular follow-ups help patients maintain independence and quality of life.
Low vision aids, enhanced lighting, and assistive technology can make daily tasks easier and improve safety at home.

Key nutrients support eye health.
- Lutein and zeaxanthin filter harmful blue light.
- Vitamins C and E act as antioxidants.
- Zinc and copper aid retinal cell function.
- Omega-3 fatty acids reduce inflammation.
Each plan is tailored to disease type and stage. Dry AMD focuses on slowing progression, while wet AMD may need periodic injections or other therapies. Regular assessments keep treatment on track.

Had my eyes checked with vision chart and received eye drops to dilate my eyes. After a very brief wait I saw Dr. Markovitz for a very thorough eye exam. The visit I had today was extremely pleasant..
Kenneth Gruen
I had an appointment with the retina specialist on Saturday morning. I'm VERY happy with my care there. Office staff was very friendly and Dr was great. I recommend this office.
Joan Schmidt
I have no complaints about the staff or the doctors I've seen over the years. Dr. Markovitz you're a gem, I love you ! Excellent care is given here.
