Macular degeneration, a leading cause of vision loss in adults over 65, comes in two main forms: dry and wet. Dry macular degeneration is more common, progressing slowly over years, while wet macular degeneration is less common but far more aggressive, causing severe vision loss in days or weeks. Both conditions affect central vision, making tasks like reading or recognizing faces challenging, but peripheral vision remains intact.
Key Differences:
- Dry AMD: Gradual vision changes due to thinning of the macula and drusen buildup. No cure exists, but lifestyle changes and supplements can slow progression.
- Wet AMD: Rapid vision loss caused by abnormal blood vessel growth and leakage under the retina. Anti-VEGF injections are the primary treatment, requiring urgent care.
Quick Comparison:
| Feature | Dry AMD | Wet AMD |
|---|---|---|
| Prevalence | 85–90% of cases | 10–15% of cases |
| Progression | Slow (years) | Fast (days to weeks) |
| Vision Loss | Mild to moderate | Severe and rapid |
| Cause | Drusen buildup, macula thinning | Abnormal blood vessel growth |
| Treatment | Supplements, lifestyle changes | Anti-VEGF injections, therapy |
If you notice blurred vision, wavy lines, or dark spots, seek immediate medical attention. Early detection and treatment can help manage symptoms and preserve vision.
Dry VS Wet Macular Degeneration – Age Related Macular Degeneration (AMD) Explained
Dry Macular Degeneration
Dry macular degeneration accounts for the majority of age-related macular degeneration (AMD) cases. Unlike its wet counterpart, this form progresses slowly, giving patients and doctors more time to manage the condition. It develops as the macula – the central part of the retina responsible for sharp, detailed vision – gradually thins over several years instead of deteriorating rapidly.
One hallmark of dry macular degeneration is the buildup of yellow deposits known as drusen beneath the retina. These deposits form when the retinal pigment epithelium (RPE) struggles to clear waste from photoreceptor cells. Over time, drusen disrupt the flow of oxygen and nutrients to the macula, causing it to thin and leading to a gradual loss of central vision.
Dry Macular Degeneration Symptoms
In its early stages, dry macular degeneration is often symptomless and typically detected during routine eye exams. As the condition advances to the intermediate stage, patients may notice mild central vision blurring and difficulty seeing in low-light conditions. In the late stage, symptoms become more severe. Central vision loss can significantly impact daily activities like reading, recognizing faces, or performing tasks that require precision. Some individuals may also experience blank spots in their central vision or see straight lines – such as doorframes or telephone poles – appear wavy or distorted. Despite these challenges, peripheral vision generally remains unaffected.
Causes and Risk Factors
Dry macular degeneration is primarily linked to aging, as the natural wear and tear on the macula leads to its gradual breakdown. With age, the retinal pigment epithelium becomes less effective at removing metabolic waste, allowing drusen to accumulate and damage the macula.
Age is the most prominent risk factor, with the condition primarily affecting individuals over 65. Genetics also play a role; having a family history of AMD or specific genetic variations, such as changes in the complement factor H gene, can increase susceptibility. Lifestyle factors further amplify the risk. Smoking, for instance, can triple the likelihood of developing AMD, as tobacco chemicals damage retinal blood vessels and accelerate tissue aging. Other contributors include high blood pressure, elevated cholesterol, and cardiovascular disease, all of which can reduce blood flow to the retina. Excessive sun exposure and unhealthy habits, such as poor diet and lack of exercise, may also heighten the risk. Understanding these factors emphasizes the importance of preventative care and early management.
Treatment Options for Dry Macular Degeneration
Currently, there is no cure for dry macular degeneration. However, several strategies can help slow its progression and preserve vision. One proven option is the use of AREDS2 supplements, which combine vitamin C, vitamin E, zinc, copper, lutein, and zeaxanthin. These supplements are specifically designed to slow disease progression in intermediate or advanced stages and should be taken under medical supervision.
Lifestyle changes play a crucial role in managing dry AMD. Quitting smoking is one of the most impactful steps, as it reduces further retinal damage. Adopting a diet rich in leafy greens and fish provides antioxidants and omega-3 fatty acids that support eye health. Managing cardiovascular health by controlling blood pressure and cholesterol, staying active, and wearing high-quality sunglasses to block UV rays are also important measures. Regular checkups with an eye care professional, along with the use of tools like an Amsler grid at home, can help monitor disease progression and detect any transition to wet macular degeneration.
While current treatments focus on slowing the condition rather than reversing damage, new therapies are under development. Clinical trials are exploring options like stem cell treatments and anti-inflammatory medications, which could lead to more effective solutions in the future. This ongoing research offers hope for better management of dry AMD and improved outcomes for patients.
Wet Macular Degeneration
Wet macular degeneration is a more aggressive form of age-related macular degeneration (AMD). While it accounts for only about 20% of AMD cases, it’s responsible for roughly 90% of the severe vision loss linked to the condition. Unlike the slower progression of dry AMD, wet AMD can lead to significant vision impairment in just days or weeks.
The hallmark of wet AMD is the abnormal growth of fragile blood vessels beneath the macula, a process called choroidal neovascularization. These vessels often leak blood and fluid into the retinal tissue, causing rapid damage to the cells responsible for sharp central vision. This quick progression makes wet AMD a medical urgency, requiring immediate attention.
Wet Macular Degeneration Symptoms
Symptoms of wet AMD tend to appear suddenly, highlighting the need for prompt medical care. One early sign is the distortion of straight lines – objects like doorframes or telephone poles may look bent or wavy. A dark or blurry spot often develops in the center of vision, making tasks like reading or recognizing faces difficult. Colors may appear duller, and patients may struggle to see clearly in dim lighting. These symptoms can escalate rapidly over a short period.
Causes and Risk Factors
Wet AMD frequently develops from dry AMD, as abnormal blood vessel growth beneath the retina triggers rapid vision loss. Several factors contribute to its progression. Age remains the leading non-modifiable risk factor, with the condition most commonly affecting those over 50. A family history of AMD and genetic predispositions also increase susceptibility.
Among modifiable risk factors, smoking plays a significant role in worsening abnormal blood vessel growth. Other contributors include cardiovascular problems, high blood pressure, and excessive exposure to sunlight. Addressing these modifiable risks can help reduce the likelihood of developing wet AMD.
Treatment Options for Wet Macular Degeneration
Given the aggressive nature of wet AMD, early intervention is essential. Anti-vascular endothelial growth factor (anti-VEGF) injections are the primary treatment. These medications work by halting the growth of abnormal blood vessels and reducing leakage beneath the retina. With timely treatment, some vision may be restored. Injections are typically given monthly at first, with the schedule adjusted based on the patient’s response. While mild discomfort during treatment is common, serious complications are rare.
Newer therapies, such as Faricimab (Vabysmo), offer a dual-action approach, providing additional options for patients who don’t respond well to traditional anti-VEGF treatments. In some situations, photodynamic therapy or laser treatments may still be used, though these methods are less common today. The primary goal of all treatments is to stabilize vision and prevent further loss, as restoring lost vision remains challenging. Regular follow-ups are crucial to monitor progress and adjust treatment as needed.
Research continues to focus on developing longer-lasting medications, combination therapies, and advanced delivery systems to reduce the frequency of injections while improving outcomes.

Dry vs. Wet Macular Degeneration Comparison
Understanding the differences between dry and wet macular degeneration is essential for recognizing early symptoms and ensuring timely care. Each type comes with its own unique characteristics and treatment approaches, which are outlined below.
Dry AMD accounts for about 85–90% of all cases and progresses slowly over several years. On the other hand, wet AMD, which represents 10–15% of cases, can lead to severe vision loss in a matter of days or weeks .
The underlying causes of these conditions also differ. Dry AMD is marked by the buildup of drusen deposits that thin the macula over time. In contrast, wet AMD involves the growth of fragile, leaky blood vessels beneath the retina, which can quickly impair vision.
Treatment options highlight another key difference. While there is no cure for dry AMD at this time, management focuses on lifestyle changes – like quitting smoking – and the use of nutritional supplements. Research into potential treatments is ongoing. Wet AMD, however, has more established treatments, including anti-VEGF injections and, in some cases, photodynamic therapy, both of which aim to control abnormal blood vessel growth. For wet AMD, treatment is typically started within two weeks of diagnosis .
Monitoring strategies also vary. Dry AMD requires regular eye exams to track gradual changes, whereas wet AMD demands more frequent monitoring, often using tools like the Amsler grid to catch any rapid shifts in vision.
