Dry and wet macular degeneration both affect the macula, the part of the retina responsible for sharp central vision, but they progress in different ways. Dry age-related macular degeneration is more common and usually develops gradually, while wet age-related macular degeneration is less common but can worsen much faster because abnormal blood vessels leak under the retina. Knowing the difference matters because symptoms, urgency, and treatment options are not the same.

What is the difference between dry and wet macular degeneration?
Both types are forms of age-related macular degeneration, often called AMD. The main difference is what is happening inside the eye.
Dry macular degeneration
Dry AMD usually develops when the macula becomes thinner over time and small yellow deposits called drusen build up under the retina. It tends to progress slowly, often over years. In the early stages, some people notice very little change, while others begin to find reading, recognising faces, or seeing in dim light more difficult.
Wet macular degeneration
Wet AMD happens when abnormal blood vessels grow under the retina and leak blood or fluid. This can distort or damage the macula more quickly. Wet AMD is generally considered more urgent because vision changes can come on suddenly and progress faster than the dry form.
Which type is more common?
Dry AMD is much more common than wet AMD. Most people diagnosed with macular degeneration have the dry type. Wet AMD accounts for fewer cases overall, but it is responsible for a larger share of severe central vision loss linked with AMD.
How symptoms can feel different
The two forms can overlap, but there are patterns that often help people tell them apart.
Common signs of dry AMD
- Gradually blurrier central vision
- Needing brighter light for reading
- Colours seeming less vivid
- Trouble recognising faces from a distance
- Slower adjustment when moving from bright to dim settings
Common signs of wet AMD
- Sudden worsening of central vision
- Straight lines appearing bent or wavy
- A dark or blank patch near the centre of vision
- Rapid change in clarity in one eye
If someone notices a sudden change, especially distortion or a dark patch in central vision, that should be treated as urgent and checked quickly by an optometrist, GP, or eye specialist.
Can dry AMD turn into wet AMD?
Yes. Some people who start with dry AMD later develop wet AMD in one or both eyes. That is one reason regular monitoring matters. An eye professional may suggest follow-up visits and, in some cases, tools such as an Amsler grid to help track changes between appointments.
What causes dry vs wet macular degeneration?
There is no single cause, but several risk factors are linked with both forms. Age is one of the strongest factors. Family history, smoking, high blood pressure, and overall cardiovascular health may also play a role. Dry AMD is linked with ageing changes and drusen build-up in the retina. Wet AMD involves abnormal blood vessel growth beneath the macula.
We usually think of dry AMD as a slower structural change and wet AMD as a more active, leaking process. That difference helps explain why wet AMD often needs faster medical treatment.
How are they diagnosed?
An optometrist or ophthalmologist can look for signs of AMD during an eye examination. Diagnosis may involve:
- a discussion of symptoms and medical history
- a dilated eye exam
- retinal imaging such as OCT scans
- sometimes fluorescein angiography if wet AMD is suspected
These tests help confirm whether the condition is dry or wet and how advanced it may be.
Treatment differences
Dry AMD treatment
There is currently no single cure for dry AMD, but management may include monitoring, regular eye checks, and lifestyle support. Depending on the person and stage, clinicians may discuss smoking cessation, diet, blood pressure management, and specific nutritional formulations for certain patients. Not every supplement suits every person, so it is worth checking what is appropriate with a health professional.
Wet AMD treatment
Wet AMD often requires specialist treatment. Anti-VEGF eye injections are commonly used to help reduce leakage and slow vision loss. In some cases, other treatments may also be considered by an ophthalmologist. Because timing matters, fast assessment is important when wet AMD is suspected.
Is one type more serious?
Wet AMD is generally considered more immediately serious because it can damage central vision more quickly. Dry AMD may still have a major impact on daily life, especially in later stages, but the pace is often slower. For families and caregivers, the key point is that sudden visual distortion or rapid loss of clarity needs urgent review.
Daily living and practical support
Whether AMD is dry or wet, early support can make daily life easier. We often suggest focusing on practical steps such as better lighting, larger print, regular eye appointments, medication review where relevant, and keeping track of any new visual changes. For older adults, it can also help to ask one family member to coordinate appointments and symptom notes.
When to seek help quickly
Book an eye check promptly if there is any new central blur, difficulty reading, or trouble recognising faces. Seek urgent assessment if straight lines suddenly look wavy, central vision drops quickly, or a dark patch appears. Those changes can point to wet AMD and are worth checking without delay.
FAQs
What are the early signs of dry vs wet macular degeneration?
Early dry macular degeneration may cause gradually blurrier central vision, reduced contrast, and a need for brighter light when reading. Early wet macular degeneration is more likely to cause sudden distortion, wavy lines, or a rapid drop in central vision.
What causes dry vs wet macular degeneration?
Dry macular degeneration is linked with ageing changes in the macula and drusen build-up under the retina. Wet macular degeneration involves abnormal blood vessels growing under the retina and leaking fluid or blood. Risk factors for both can include age, smoking, family history, and cardiovascular factors.
How is dry vs wet macular degeneration diagnosed?
Dry and wet macular degeneration are diagnosed through an eye exam, usually with dilated retinal assessment and imaging such as OCT. If wet macular degeneration is suspected, an eye specialist may use additional tests to look for leaking blood vessels.
Can dry vs wet macular degeneration be treated or slowed down?
Dry macular degeneration is usually managed with monitoring, lifestyle measures, and in some cases nutritional support recommended by a clinician. Wet macular degeneration often needs medical treatment such as anti-VEGF injections to help slow progression and protect vision.
When should you see an optometrist or GP for dry vs wet macular degeneration?
You should book an appointment if you notice ongoing central blur, trouble reading, or difficulty recognising faces. You should seek urgent help if straight lines look wavy, vision changes suddenly, or a dark patch appears in the centre of vision.
