FORMS OF AMD
Dry AMD is a gradual process of deterioration as retinal cells die and are not replaced.. Many people carry on as normal for some time, including continuing to drive. This process can take months or even years. There are no cures for DRY AMD so far. However, 10-15% of DRY AMD cases develop into WET AMD, where abnormal blood vessels grow into the macular. These leak blood or fluid, leading to scarring of the macula and rapid loss of central vision.
WET AMD requires fast referral to a retinal specialist
If you have DRY AMD and your Optometrist detects a sudden change in your vision it is vital that referral to a retinal specialist is sought at once.
If you have AMD in one eye, it may affect the other eye in a few years
Gaps in vision, dark spots- especially in early morning
Objects change shape, size or colour- or disappear
Bright light glaring and uncomfortable. Change from dark to light difficult to adapt to.
Words may disappear when reading
Straight lines such as door frames, window frames and lamp posts may look distorted.
The macula is a small portion of the retina. Though quite small it enables central vision, most of the colour vision and the fine detail of what we view. The rest of the retina handles peripheral vision.
The terms DRY and WET refer to two forms of deterioration of the macular.
