Age related macular degeneration (AMD)
The macula is the central part of the retina responsible for fine vision, reading and perception of colour. AMD is a deterioration in this part of the retina due to the build up of waste material underneath the retina. AMD usually causes a slow deterioration in the quality of central vision.
- Decrease in central vision
- Loss of colour appreciation
- Distortion
This is a gradual degeneration of the macula. Most people notice blurring of vision, greater reliance on bright light and difficulty reading. In general vision deteriorates very slowly. The majority (75%) of people with AMD have early, or dry AMD. Dry AMD can progress to wet AMD with a rapid decline in vision.
Wet, or neovascular, AMD is due to the development of blood vessels underneath the retina in response to degeneration. These blood vessels can leak fluid and bleed leading to a rapid reduction in vision, especially if untreated.
If you notice a sudden change in vision please contact us to arrange an urgent appointment. Blurred vision or distortion can indicate the start of wet AMD.
Intravitreal injections (injections into the centre of the eye) are used to treat wet AMD. They are generally successful but early treatment is important.
