Central vision eye condition
Macula Degeneration
Macula degeneration can affect central detailed vision, including reading, faces, and fine detail.
The macula is the central part of the retina at the back of the eye. It is responsible for sharp, detailed central vision.
Macula degeneration, often called age-related macular degeneration or AMD, can make central vision blurred, distorted, missing, or harder to use. Peripheral, or side, vision is usually less affected.

Why the macula matters
The macula is small, but it is very important for detailed visual tasks.
Reading and fine detail
The macula helps with reading, recognising small print, seeing detail, and doing close tasks.
Recognising faces
Central vision helps with recognising faces, watching television, and seeing what you are looking directly at.
Colour and contrast
The macula also helps with colour, contrast, and sharp central vision.
Macula changes may not be obvious at first
Early macula degeneration may not cause obvious symptoms. Sometimes one eye can compensate for the other, making changes harder to notice without an eye exam or checking each eye separately.

How macula degeneration can affect vision
Macula degeneration usually affects the centre of the vision rather than the side vision. This can make detailed tasks harder, even if you can still move around reasonably well.
Straight lines may look bent or wavy, words may appear blurred or missing, or a smudge, shadow, or blank area may appear near the centre of vision.
Any new distortion, new central blur, or sudden change in central vision should be checked promptly.
Sudden central vision changes need prompt attention
Please phone us promptly if you notice new distortion, a new dark or blank patch, sudden central blur, a sudden change in reading vision, or straight lines looking wavy.
These symptoms do not always mean macula degeneration, but they should not be ignored.
Types of macula degeneration
Macula degeneration is often described as dry AMD or wet AMD. The type and severity affect monitoring and treatment options.
Dry macula degeneration
Dry AMD is the more common form. It often changes gradually over time and may be monitored with eye exams, OCT imaging, and home vision awareness.
Wet macula degeneration
Wet AMD can develop when abnormal blood vessels grow and leak under the retina. It can progress more quickly and usually needs prompt specialist assessment.
Possible signs of macula degeneration
Symptoms can vary depending on the type, stage, and whether one or both eyes are affected.
Distortion
Straight lines, door frames, tiles, or text may look bent, wavy, or uneven.
Blurred central vision
Reading, faces, television, or fine detail may become blurred or harder to see clearly.
Dark or missing area
Some people notice a smudge, shadow, blank patch, or missing area near the centre of their vision.
How macula degeneration is checked
A full eye exam helps check whether macula changes are present and whether further monitoring or referral is needed.
Vision and symptom history
We ask about your vision, symptoms, family history, general health, and whether symptoms are gradual or sudden.
Retinal examination
The optometrist examines the retina and macula for signs of macula changes, bleeding, fluid, or other eye health concerns.
OCT and retinal imaging
OCT gives a detailed cross-section of the macula and can help detect fluid, thinning, deposits, or structural change.
Our eye exam includes macula imaging
At Waipapa Eyecare, our complete eye exam includes retinal imaging and OCT. These help us check the macula and compare findings over time where needed.
If changes are detected, we can explain what we have found and discuss whether monitoring, further testing, or referral is appropriate.
Managing macula degeneration risk
Not all risk factors can be changed, but some lifestyle and health factors may be worth discussing.
Smoking
Smoking is an important modifiable risk factor for macula degeneration. Stopping smoking may help reduce future risk.
Diet and general health
A healthy diet, general health management, and regular eye checks may be useful parts of an overall plan.
Family history
Tell your optometrist if macula degeneration runs in your family, as this may affect how often monitoring is recommended.
Supplements are not one-size-fits-all
Some people with certain stages of macula degeneration may be advised to consider specific eye supplements. They are not suitable or necessary for everyone and should be discussed with an eye care professional, especially if you smoke, have smoked, or have other health conditions.
If wet AMD is suspected
Wet AMD usually needs prompt specialist assessment because treatment may be time-sensitive.
Prompt referral
If signs suggest wet AMD, referral to an eye specialist may be recommended urgently.
Specialist testing
The specialist may use additional imaging and tests to confirm whether treatment is needed.
Treatment options
Wet AMD treatment may include injections into the eye to reduce leakage and help preserve vision where appropriate.
Related eye health information
Central vision changes can have more than one cause. A complete eye exam helps check the bigger picture.
OCT eye scans
OCT provides detailed 3D imaging that can help assess the macula, retina, and optic nerve.
Cataracts
Cataracts can make vision cloudy, hazy, glary, or less clear over time.
Glaucoma
Glaucoma can affect the optic nerve and may affect side vision before central vision.
Does macula degeneration cause complete blindness?
Macula degeneration usually affects central vision rather than side vision. It can have a major effect on reading and detail, but many people keep useful peripheral vision.
Can I check each eye at home?
It is useful to be aware of each eye separately. Cover one eye at a time when checking reading, straight lines, or any new distortion. New changes should be checked promptly.
Is all macula degeneration treated with injections?
No. Injections are generally associated with wet AMD treatment. Dry AMD is usually monitored unless specialist treatment or advice is appropriate for a particular stage.
How often should I be checked?
This depends on your age, symptoms, family history, macula appearance, OCT findings, and whether changes are stable or progressing.
