Macular Degeneration Treatment Options: Dry and Wet AMD

Wet AMD is primarily treated with anti-VEGF injections into the eye, which can stabilize or improve vision by blocking abnormal blood vessel growth. Dry AMD has no cure, but the AREDS2 antioxidant supplement formula reduces the risk of progression to late-stage disease in eligible patients. A retina specialist manages both forms.

Why dry AMD and wet AMD are treated differently

Age-related macular degeneration (AMD) has two distinct forms, and the distinction matters enormously for treatment 1.

Dry AMD progresses slowly as the retinal pigment epithelium thins and small deposits called drusen accumulate beneath the macula. There is currently no treatment that reverses dry AMD, but specific nutritional supplements can slow its progression in certain patients.

Wet AMD develops when abnormal blood vessels grow beneath the retina (a process called choroidal neovascularization). These vessels are fragile and can leak fluid or blood, causing rapid central vision loss. Wet AMD is a medical urgency — the sooner treatment begins after onset, the better the visual outcome 1. Anti-VEGF injections are the standard of care and have transformed wet AMD management over the past two decades.

Anti-VEGF injections: the mainstay of wet AMD treatment

VEGF (vascular endothelial growth factor) is a protein that drives the growth of the abnormal blood vessels in wet AMD. Anti-VEGF medications block this protein, causing the vessels to stop growing and often causing them to shrink, which allows fluid beneath the retina to reabsorb.

These medications are delivered by injection into the vitreous (the gel inside the eye). The procedure is performed in an outpatient office setting by a retina specialist, using a very fine needle. The eye is numbed beforehand, and most patients tolerate the procedure well.

Several anti-VEGF agents are used in clinical practice. The treating retina specialist chooses based on clinical factors, practice patterns, and patient preferences. Injection schedules vary — some patients begin with monthly injections and then extend the interval as their disease stabilizes; others are monitored closely and treated when imaging shows signs of fluid 1.

With consistent treatment, many patients with wet AMD can maintain or even modestly improve their central vision. Stopping treatment prematurely is a common reason for vision loss in wet AMD — the disease tends to return if injections are discontinued 1.

AREDS2 supplements: slowing dry AMD progression

The Age-Related Eye Disease Study 2 (AREDS2) tested a specific formulation of antioxidants and minerals in people who had intermediate AMD in one or both eyes, or advanced AMD in one eye. The AREDS2 formula includes: - Vitamin C - Vitamin E - Lutein and zeaxanthin - Zinc - Copper

In people who met the enrollment criteria for the AREDS2 trial, this supplement formula reduced the risk of progression to advanced AMD over five years [1, 2]. It is not a cure and does not reverse existing damage.

Important caveats: - AREDS2 supplements are not recommended for people with early AMD or no AMD — the benefit was shown in people with intermediate or advanced (one eye) disease. - People who currently smoke or have recently stopped smoking should discuss their specific situation with their doctor, as some components interact with smoking history. - Generic AREDS2 formulations exist and can be substantially less expensive than branded versions; the key is matching the exact tested formula.

Your ophthalmologist or retina specialist will tell you whether AREDS2 supplements are appropriate for your stage of disease 1.

Lifestyle factors that may support eye health

While no lifestyle change can reverse AMD, several factors are associated with AMD risk and progression:

  • Stopping smoking is the single most important modifiable lifestyle factor for AMD. Smoking meaningfully increases the risk of developing and progressing AMD 1.
  • Diet rich in leafy green vegetables (spinach, kale, collards) and other colorful produce provides lutein, zeaxanthin, and antioxidants that are concentrated in the macula.
  • Cardiovascular health: managing blood pressure and cholesterol according to your primary care provider's recommendations may have benefits beyond heart health.
  • UV protection: wearing sunglasses that block UV-A and UV-B light is reasonable, though the evidence linking UV exposure to AMD is less definitive than for some other eye conditions.
  • Regular exercise and maintaining a healthy weight may lower systemic inflammatory burden.

Other treatment approaches (photodynamic therapy, laser)

Before anti-VEGF medications became available, photodynamic therapy (PDT) and thermal laser were used for certain subtypes of wet AMD. These approaches are now rarely used as primary treatment because anti-VEGF injections have proven more effective at preserving and improving vision. In specific clinical situations, retina specialists may still consider them 1.

Several new treatments for geographic atrophy (advanced dry AMD with extensive retinal cell loss) have received regulatory attention in recent years. This is an evolving area of research. Your retina specialist will be the best source of information about the latest options.

What kind of doctor treats AMD?

  • Optometrists and general ophthalmologists can monitor early and intermediate dry AMD and advise on supplements and lifestyle.
  • Retina specialists (vitreoretinal surgeons and medical retina specialists) manage wet AMD and advanced dry AMD, including performing anti-VEGF injections. If your eye doctor sees signs of wet AMD on imaging — particularly fluid on OCT — you are typically referred to a retina specialist promptly 1.

Common questions

Are the injections for wet AMD painful?

Most patients find the procedure more manageable than they expected. The eye is numbed with anesthetic drops, and the injection itself is typically brief. Some patients feel pressure; a sharp pain during the injection is unusual and worth reporting to the doctor. Afterward, mild discomfort or a foreign-body sensation for a day is common.

How often do I need AMD injections?

This varies considerably by patient and by medication. Some people need monthly injections indefinitely; others are able to extend to every two or three months once their disease is stable. The retina specialist monitors the retina with OCT imaging and adjusts the schedule based on whether fluid is present.

Can dry AMD turn into wet AMD?

Yes. People with dry AMD have a lifetime risk of developing wet AMD, particularly if they have intermediate AMD or large drusen. This is why regular follow-up exams and home Amsler grid monitoring are important — to catch the conversion early.

Is there a cure for AMD?

There is currently no cure for AMD. Anti-VEGF injections can stabilize or improve vision in wet AMD for many patients, and AREDS2 supplements can slow progression in intermediate or advanced dry AMD in one eye. Research into gene therapy and other approaches is ongoing.

When to seek same-day eye care

  • —Sudden distortion of straight lines (new waviness of door frames, text, or lines)
  • —A new dark spot or blank area in the center of your vision
  • —Sudden blurring that did not exist yesterday
  • —Any rapid change in vision if you have a known AMD diagnosis

New or worsening distortion, a new blind spot, or any sudden vision change in a person with AMD should be evaluated the same day — call your retina specialist or ophthalmologist immediately. If the office is closed, go to an urgent eye care center or emergency department.
