What is Age Related Macular Degeneration (AMD)?
Age Related Macular Degeneration (AMD) is the leading cause of sight loss in the UK, affecting more than 600,000 people. It occurs in people of 65+, but there are less common types that can affect people at any age.
“The earlier the AMD is diagnosed, the greater the chances of treatment and maintaining your vision”
A 3D OCT Scan can often detect the early stages of Age Related Macular Degeneration (AMD). Regular eye examinations are important so the Optician can monitor you vision, diagnose and recommend treatment if necessary. We have easy Online Booking for appointments or call 020 8759 9395.
There are two principle types: dry AMD and wet AMD. Dry AMD is typically associated with age and is slower in onset. Wet AMD tends to be more sudden in onset and thus more serious, occurring at any age.
In both types the central part of the eye, known as the macular, deteriorates resulting in a loss of central vision. It involves a build-up of deposits in the eye that can cause a gradual decline in your central field of vision causing damage to the macula.

What are the symptoms?
Most people do not experience symptoms in the early stages of Age Related Macular Degeneration (AMD), especially if dry degeneration is present in only one eye. The most common symptoms are straight lines that may appear wavy and there may be patches in your vision. As the macular cells deteriorate, people may notice the following visual changes:
Straight lines may appear bent or wavy such as door frames and lamp post
Dark spots or gaps may appear in your vision especially first thing in the day (they may look like smudges on a glass)
Words may disappear when you are reading
You may find difficulty in recognising faces
Bright light can be uncomfortable as well as when changing from dark to light environments
Objects may appear to change in shape, size, colour or move or disappear
Colours can appear faded
You may turn your head off centre to see things better
Because Age Related Macular Degeneration mainly affects the loss of central vision, it makes it difficult for people to see objects in front of them such as reading and recognising faces.

What are the causes?
The cause of Macular Degeneration is unknown, however there are certain factors that are believed to heighten the risk of developing the condition including:
Age - macular degeneration is most prominent in over 65s
A family history of the condition
Poor diet - especially one which lacks antioxidants or is high in saturated fat
High blood pressure
Overexposure to UV light
Gender - more women are diagnosed than men
Side effects of some general health medications
What is the treatment?
There are two types of AMD, classified as dry or wet. There is no known effective treatment for dry form of macular degeneration, although lifestyle choices and nutrition may play a role in minimising further progression (see our tips below).
“Wet AMD can often be treated if it is caught early enough, and requires referral to a specialist eye doctor, known as an Ophthalmologist, who will discuss the options available.”
Tips that may prevent or slow down macular degeneration
Evidence shows that improvements to your diet including foods rich in certain nutrients such as lutein and zeaxanthin, and increasing the intake of antioxidants can help reduce the risk of macular degeneration. These are found in spinach, kale, broccoli and sprouts, as well as in specific AMD nutritional supplements. Have a diet rich in Omega 3 which includes oily fish and nuts, and a diet low in saturated fat to maintain a healthy weight and high blood pressure.
Those with AMD often find increased lighting or contrast helpful. The use of electronic devices, such as tablets, can prove very useful, as they can be adjusted for illumination and contrast. Protect your eyes from UV light and high energy blue light with UV and blue light absorbing sunglasses, spectacles and UV blocking contact lenses. Although macular degeneration mainly affects the over 60s, the damage happens throughout your life. It is especially important for children to protect their eyes from UV light as their eyes are more vulnerable. We have a wide range of sunglasses for children from age 3 months.
These tips will also help with macular degeneration:
Have a regular eye exam and include an advanced eye health check in the form of a 3D OCT Scan. This is especially important if you are over 60 or have a family history of macular degeneration (AMD).

The Amsler Grid is a good way for people to monitor their own changes in vision for the signs of AMD because the Optician may only see you every 6 or 12 months. It is especially important if the Optician notices changes at the back of your eyes.
Make sure your screen is at 100% or print the grid
If you need glasses wear you reading glasses (but not varifocals)
Hold the grid at your normal reading distance, or have the screen at your normal reading distance, about 30cm/12 inches away from your face
Cover one eye at a time and focus on the dot in the centre of the grid
Are all the lines straight?
Do you see any distortion, or any broken or wavy lines?
Do you see any missing patches?
If the lines appear wavy, distorted or broken in any way you should make an appointment to see your Optometrist or Ophthalmologist immediately
