Age-related macular degeneration, or AMD, damages the macula, the small central part of the retina at the back of the eye. The macula helps you see fine detail directly in front of you. When it is damaged, reading, recognizing faces, and other everyday tasks can become harder. AMD mainly affects central vision; side vision is usually preserved. National Eye Institute: AMD
New wavy lines, a new dark or missing patch in your central vision, or a sudden change in sight need urgent attention. Contact an eye-care professional right away rather than waiting for your next routine appointment. American Academy of Ophthalmology: Understanding Macular Degeneration
Dry AMD and wet AMD: What is the difference?
Dry AMD is the more common form. Deposits called drusen and changes in the tissues beneath the retina can develop. It often progresses slowly, and early disease may cause no noticeable symptoms. An advanced form, called geographic atrophy, involves the loss of retinal cells and can cause significant central vision loss. American Society of Retina Specialists: Dry AMD and Geographic Atrophy
Wet AMD develops when abnormal blood vessels grow beneath the retina and leak fluid or blood. It can damage central vision quickly. Someone with dry AMD can develop wet AMD, so new changes in vision should be checked promptly. The terms “wet” and “dry” describe changes inside the eye, not whether the eyes feel watery or dry. American Society of Retina Specialists: AMD
What changes might you notice?
AMD may cause:
- Straight lines, such as doorframes or lines of text, to appear bent or wavy.
- Blurry, dim, or missing areas in the center of vision.
- Difficulty reading or recognizing faces.
- Trouble seeing in dim light or adjusting to darker surroundings.
- Colors that seem less vivid.
You can have AMD before these changes appear. Symptoms alone cannot tell you which type you have. American Society of Retina Specialists: Dry AMD and Geographic Atrophy
Who is at risk, and how is AMD found?
Risk increases with age, particularly after 55. A family history of AMD and smoking also increase risk. Regular comprehensive eye examinations can find changes before you notice a problem. Ask your eye-care professional how often you should be examined based on your age, family history, and eye health. National Eye Institute: AMD
A dilated eye examination lets the clinician inspect the retina. An optical coherence tomography scan, or OCT, provides detailed images of retinal layers and helps assess changes such as fluid or thinning. Further imaging may be needed to identify abnormal blood vessels. American Society of Retina Specialists: AMD
If you have AMD, your clinician may recommend monitoring at home with an Amsler grid. Check each eye separately as instructed, and report new distortion or missing areas immediately. Home checks support follow-up care but do not replace eye examinations. American Academy of Ophthalmology: Daily Vision Checks
Treatment depends on the type and stage
Wet AMD: Anti-VEGF medicines, given as eye injections after numbing, reduce leakage from abnormal blood vessels. They can preserve vision and sometimes improve it, but they do not cure AMD. Repeated treatment and monitoring are usually necessary, with timing tailored to the individual eye. National Eye Institute: Treatments for Wet AMD
Selected cases of geographic atrophy: In the United States, injections of pegcetacoplan (Syfovre) or avacincaptad pegol (Izervay) can slow the enlargement of damaged areas. They do not restore lost vision or cure the disease. A retina specialist can help weigh the expected benefit against the treatment burden and risks, including infection, inflammation, and development of wet AMD. Availability differs by country.

AREDS2 supplements: This specific vitamin-and-mineral formula can reduce the risk of progression in people with intermediate AMD and may be appropriate for selected people with advanced AMD. It does not prevent AMD from starting and is not a general eye-health supplement for everyone. Newer research also supports a possible benefit for some people whose geographic atrophy has not reached the very center of the macula. Ask your clinician whether it fits your diagnosis and other medicines. Current or former smokers should avoid older AREDS formulas containing beta-carotene because of increased lung-cancer risk; AREDS2 uses lutein and zeaxanthin instead.

Everyday steps that help
Avoid smoking, stay physically active, include leafy green vegetables and fish in a balanced diet, and work with your healthcare team to manage blood pressure and cholesterol. Keep recommended appointments, even when your vision seems unchanged. National Eye Institute: AMD
If vision loss is affecting daily life, ask about low-vision rehabilitation. Better lighting, magnifiers, larger text, and accessibility settings can help you make the most of your remaining sight. National Eye Institute: Low Vision
Know your diagnosis, keep your follow-up visits, and act quickly on new vision changes.
