Macular Degeneration

Macular degeneration occurs when the cells of the macula become damaged and stop working. This can occasional happen at any age but more commonly in older people. This condition is then called age related macular degeneration or AMD.

Age related Macular Degeneration is the most common cause of bad sight in people over 60, but it rarely leads to complete loss of vision as it affects the macula which is situated at the centre of the retina at the back of the eye, so that only central vision, and not peripheral vision, is lost.

There are two types of AMD, called wet macular degeneration and dry macular degeneration.

The most common type is dry AMD and occurs in about 90% of instances of AMD. Some of the cells stop working and gradual loss of colour or central vision occur in the central field of vision.

Wet AMD occurs when there is a build up of fluid under the retina. It accounts for about 10% of cases. It causes bleeding and scarring and can develop swiftly. However it can be treated with lasers if caught in the early stages.

Age related Macular Degeneration will usually occur in both eyes, although one eye may become affected earlier than the other.

If you suspect that you may have AMD in one or both eyes, you must see an optometrist as soon as possible as early treatment in the case of wet AMD is
advisable.

Unfortunately glasses or stronger glasses will not improve your vision where it has been affected by AMD.
