Causes and Risk Factors
AMD is linked to age-related changes in the retina. The exact cause can vary, but several factors may increase the likelihood of developing AMD or of the condition progressing over time.
AMD / Medical Retina
Age-Related Macular Degeneration / AMD
Understanding Changes in Central Vision Caused by AMD
Age-related macular degeneration, often called AMD, affects the macula – the part of the retina responsible for sharp central vision. It can make activities such as reading, recognising faces, watching television or driving more difficult. At IOES, our specialist team can assess changes in your vision and guide you towards the most appropriate next step.
Overview
AMD is a condition that affects central vision rather than side vision. It usually develops later in life and may affect one or both eyes. Some people notice gradual changes over time, while others can experience more sudden distortion or loss of central detail, particularly if wet AMD develops.
- Affects the macula, which supports detailed central vision
- Can make reading, driving or recognising faces more difficult
- May affect one or both eyes
- Can develop gradually or change more quickly depending on the type of AMD
- Early assessment helps identify whether monitoring, treatment or support is needed
Symptoms
AMD symptoms can be subtle at first, especially if only one eye is affected. Changes may become more noticeable when reading, looking at faces, using screens or checking straight lines.
- Blurred or reduced central vision
- Straight lines appearing wavy or distorted
- Difficulty reading small print or seeing fine detail
- Trouble recognising faces or seeing clearly in low light
- A dark, blurred or empty patch in the centre of vision
When to Seek Help
You should arrange an eye assessment if you notice new or changing central vision symptoms. Prompt assessment is especially important if changes happen suddenly or if straight lines begin to look distorted, as some forms of AMD may need timely treatment.
It is important to have your eyes assessed if:
How It Is Diagnosed
At IOES, AMD is diagnosed through a detailed retinal assessment. The aim is to understand the type and stage of AMD, check whether there are signs of fluid or bleeding, and identify whether treatment or monitoring is needed.
Diagnosis and Next Steps
Once your assessment is complete, your clinician will explain whether AMD is present, what type or stage it appears to be, and what this may mean for your vision. Depending on the findings, the next step may include monitoring, lifestyle advice, treatment for wet AMD, or support for living with reduced central vision.
Treatment Overview
AMD treatment and support depend on the type and stage of the condition. Some forms of dry AMD may be monitored over time, with advice on eye health, lifestyle and visual support. Wet AMD may require prompt treatment to help control abnormal leaking blood vessels and reduce the risk of further central vision loss. AMD Treatment should explain the available care pathways in more detail, including monitoring, injections where appropriate, follow-up and ongoing support.
Frequently Asked Questions
What is AMD?
AMD is an age-related condition that affects the macula, the part of the retina used for detailed central vision. It can make reading, recognising faces and seeing fine detail more difficult.
What is the difference between dry and wet AMD?
Dry AMD is usually more gradual and is linked to changes in the macula over time. Wet AMD can develop when abnormal blood vessels grow and leak under the retina, which may cause faster changes in central vision and may need prompt treatment.
Does AMD cause complete blindness?
AMD mainly affects central vision rather than side vision. It can have a significant impact on reading, driving and recognising faces, but it does not usually cause total blindness.
Can AMD be treated?
Treatment depends on the type and stage of AMD. Wet AMD may be treated with eye injections where clinically appropriate. Dry AMD is usually monitored, with advice and support focused on protecting vision, managing risk factors and maintaining independence.
When should I seek urgent advice?
You should seek prompt eye assessment if you notice sudden distortion, a new blank or dark patch in central vision, or a rapid change in one eye. These symptoms may need timely specialist review.
