Medications That Cause Macular Degeneration

Macular degeneration is a serious condition that can affect vision as we age, particularly for seniors. It is a progressive eye disease that primarily impacts the macula, the part of the retina responsible for central vision. Many people may not realize that certain medications could increase their risk of developing macular degeneration¹. Being aware of these medications can help individuals make informed choices in consultation with their healthcare providers.

What is Macular Degeneration?

Macular degeneration, or age-related macular degeneration (AMD), is a common eye condition among people over 50. It causes vision loss in the center of the field of vision, which can interfere with activities like reading, driving, and recognizing faces². While genetics and lifestyle factors play a significant role, some medications have been linked to an increased risk of AMD.

Medications Linked to Macular Degeneration

Several common medications may be associated with a higher risk of macular degeneration. Here are a few categories of medications that may pose this risk:

1. Corticosteroids

Corticosteroids are often prescribed to reduce inflammation in the body. However, long-term use of corticosteroids, especially at high doses, has been linked to increased pressure in the eyes and potential damage to the retina, including the macula³. Conditions such as arthritis, asthma, and autoimmune diseases may require corticosteroids, but alternative medications or dosages may be worth discussing with a healthcare provider.

2. Antipsychotic Medications

Certain antipsychotic medications, commonly used to treat conditions like bipolar disorder and schizophrenia, have been associated with potential eye complications. Drugs in this category may increase the risk of macular degeneration due to their impact on blood flow to the retina⁴. Patients taking these medications should be aware of these risks and consider regular eye check-ups to monitor their eye health.

3. Blood Pressure Medications

Some blood pressure medications, specifically vasodilators, can impact blood flow to the retina, leading to macular degeneration over time. High blood pressure medications are crucial for managing cardiovascular health, but patients should speak to their doctor about any potential side effects on their vision¹.

4. Anti-Malaria Drugs

Medications used to treat malaria, such as chloroquine and hydroxychloroquine, have long been associated with retinal toxicity. While these drugs are effective for conditions like lupus and rheumatoid arthritis, they pose a risk of macular degeneration with prolonged use². Patients prescribed these medications for extended periods are encouraged to have regular eye exams.

Protecting Your Vision

While some medications are essential for managing chronic conditions, discussing potential side effects with a healthcare provider can help mitigate risks to eye health. Here are some ways to protect your vision if you're taking these medications:

• Regular eye exams to monitor for early signs of macular degeneration.
• Consulting with a healthcare provider about alternative medications or adjusted dosages.
• Maintaining a healthy lifestyle with a diet rich in vitamins and nutrients beneficial to eye health, such as vitamins C and E, lutein, and zeaxanthin.

If you are concerned about your medications and their impact on your eye health, it's essential to consult with an eye care professional who can provide guidance tailored to your needs.

Macular degeneration is a condition that requires vigilance, especially for those taking medications that may contribute to its onset. By staying informed and proactive, seniors can take steps to protect their vision and enjoy a better quality of life³.
