There are two types of ARMD, the so called "Dry" variety and the "Wet" type. The good news is that the early stages of ARMD don't usually cause any serious problems, and the other good news is that there are treatments now that can control the more serious "Wet" variety. But the "not so good" news is that there is no current cure for either types and no specific active treatment at all for the "Dry" variety!
The disease is caused by problems with the lining at the back of the eye where light entering the eye is turned into electrical impulses and transmitted to the brain in order to reach "consciousness". In the direct "Visual Axis" of the eye where we do most of our seeing, there is an area known as the Macular, which is where there is a massive concentration of our light receptors. When these are damaged by ARMD, then we lose vision in that area - leaving a blanked out area smack bang in the middle of our vision!
Early detection is important and one of the tools that are used is the Amsler Grid.
- Any of the lines look wavy, blurred or distorted.
- If any areas are missing or there are dark areas in the grid.
- If you cannot see all corners and sides of the grid.
And remember to test both eyes.
For the more serious Wet ARMD, new generation drugs can control the disease, and can conserve sight - so please don't take any risks, get your eyes checked: they're very precious!
