If you’ve received a diagnosis of macular degeneration, it’s essential to grasp how this eye condition advances and what measures you can take to slow it down. While there isn’t a cure yet, we can offer specific treatments and therapies that may help you safeguard your vision for years to come.
What Is Macular Degeneration?
Macular degeneration, also known as age-related macular degeneration (AMD), stands as one of the primary causes of vision loss and blindness among individuals aged 55 and older. This ailment involves the deterioration of the macula, which is the central region of the retina. In its very early stages, AMD might not exhibit noticeable symptoms. However, as it progresses, it can significantly impact everyday activities like driving, watching TV, or looking at family photos.
There are two primary types of macular degeneration:
Dry AMD: This more prevalent form develops gradually due to the thinning of macular tissue and the formation of small deposits called drusen on the retina.
Wet AMD: This less common but more severe form is caused by the growth of abnormal blood vessels beneath the retina, which can lead to bleeding or fluid leakage.
Diagnosing AMD:
Eye doctors typically diagnose AMD through:
- A pupil dilation exam
- Digital Retinal Image or Optical Coherence Tomography (OCT)
- Amsler grid test
- Phases of AMD Progression:
The pace of AMD progression depends on the type, early diagnosis, and treatment. Here are the phases of AMD:
First Phase of Dry AMD:
In the initial phase of dry AMD (the more common and less serious form), eye doctors identify small drusen deposits on the retina during a comprehensive eye exam. Patients usually have no symptoms or vision loss at this stage.
Second Phase of Dry AMD:
In the second phase, the drusen becomes larger, and the retina starts to thin out, resulting in the loss of neural tissue. The retinal pigment epithelium layer (RPE), responsible for supplying nutrients to the retina and absorbing light, may become damaged. This can significantly affect vision.
Third Phase of Dry AMD:
In this phase, the growth of drusen becomes more severe, and the RPE layer is extensively damaged. Vision declines, making daily activities more challenging, and functional blindness can occur. Patients may require low vision aids to enhance daily life.
Wet AMD:
Wet AMD progresses more rapidly than dry AMD since it’s caused by the development of fragile blood vessels. These abnormal blood vessels grow beneath the retina and can easily leak fluid or blood, leading to sudden or rapid vision decline.
How Fast Does Macular Degeneration Progress?
Dry AMD typically progresses over several years, often within a decade, from initial diagnosis to significant vision loss. However, appropriate treatment can reduce the risk of substantial vision loss, though the disease’s course can be unpredictable, emphasizing the need for regular eye exams.
Can Macular Degeneration Be Stopped?
While there’s no complete cure for halting macular degeneration, early detection, treatment, and lifestyle improvements can significantly increase the chances of preserving vision. Several strategies can aid in preserving vision and slowing AMD progression:
- Regular comprehensive eye exams
- Smoking cessation
- A diet rich in leafy greens, orange-colored vegetables and fruits
- Foods high in omega-3 fatty acids, like oily fish
- AREDS-2 vitamins are designed to slow AMD progression
- Sunglasses that block 100% of UV rays
- Maintaining a healthy weight
- Regular exercise

Frequently Asked Questions with Our Optometric Team:
Q: Is macular degeneration hereditary?
A: Having a family history of AMD, such as a parent or sibling with the condition, increases your risk of developing it. Therefore, it’s essential to share your family’s health history with your eye doctor and schedule regular comprehensive eye exams.
Q: Does dry macular degeneration progress to wet AMD?
A: Wet AMD, which is also known as advanced neovascular AMD, is a relatively uncommon form of late-stage AMD characterized by a more rapid deterioration of vision. Wet AMD always occurs in the late stage of the disease and can develop from any stage of dry AMD. It occurs when abnormal blood vessels grow in the rear of the eye, leading to damage in the macula.
