How to prevent dry AMD from worsening?

Question

Hello doctor,

My dad is 76 years old and was told he has early dry macular degeneration. He is still able to read and drive, but is very anxious about losing his vision. His doctor gave him vitamins to slow it down, but are there any other treatments he can try now before it gets worse? He also has diabetes and high blood pressure—do those make AMD (age-related macular degeneration) progress faster? We want to do everything we can early while he still has good sight. Should he see a retina specialist regularly, or is an optometrist enough? He is really scared of going blind.

Kindly help

Hello,

Welcome to icliniq.com

I can understand your concerns.

It is completely understandable that your dad is anxious—dry macular degeneration (AMD) can be emotionally overwhelming, especially when vision is still mostly intact. The good news is that there are proactive steps he can take now to slow progression and protect his sight. You are asking all the right questions—here is a clear plan:

1. What is early dry AMD?

In early AMD, small deposits called drusen form under the retina. It typically progresses slowly over the years, and not everyone goes on to advanced AMD. Vision usually remains good in the early stages, but proactive care is key to preserving it.

2. Yes, diabetes and high blood pressure matter

Both can worsen AMD progression and increase the risk of vision loss:

Poor blood vessel health affects retinal circulation.
Diabetic retinopathy can coexist with AMD, compounding risks.
Keeping tight control of blood sugar and blood pressure is one of the most important things your dad can do.

3. What can he do now?

A. Continue the AREDS2 formula

The AREDS2 (Age-Related Eye Disease Study 2) vitamin supplement is the only proven treatment to slow progression of intermediate AMD.
It contains lutein, zeaxanthin, vitamin C, vitamin E, zinc, and copper.
Make sure he’s on AREDS2 and not a basic multivitamin.

B. Lifestyle changes that help

Quit smoking (if applicable)—it’s the top modifiable risk factor.
Eat a Mediterranean-style diet rich in greens, Oily fish (omega-3s), and berries and nuts
Exercise regularly—good for retinal blood flow and managing BP (blood pressure) or diabetes.

C. Daily home monitoring

Use an Amsler grid daily to check for vision distortions. If he sees waves, blank spots, or sudden changes, call his eye doctor immediately.

4. Should he see a retina specialist?

Yes—a retina specialist is strongly recommended, especially since he has systemic conditions (diabetes, hypertension). Early AMD can turn into wet AMD, which requires urgent treatment. An optometrist is helpful for routine care, but a retina specialist can track subtle progression and monitor for conversion to wet AMD and offer newer options in clinical trials.

5. Are there any emerging treatments?

For early dry AMD, no medications are FDA (Food and Drug Administration)-approved yet, but clinical trials are ongoing (including stem cell and gene therapies). Subthreshold laser therapy and low-level light therapy (LLLT) are being explored in some clinics—results are still mixed.

6. Reassurance you can give him

Most people with early dry AMD do not go blind. With proper monitoring, vitamins, and systemic disease control, he can preserve functional vision for many years. Catching signs of wet AMD early is crucial—treatment with anti-VEGF (anti-vascular endothelial growth factor) injections can preserve or improve vision if caught early.

I hope I have solved your query.

Thank you.
