The macula is part of the retina at the back of the eye. If the eye were a camera then the retina is the film inside the camera that captures light energy, converting it into electrical impulses that are then sent down the optic nerve to the brain. Using the same analogy the optic nerve is thus equivalent to the cable that connects the camera to the computer.
The entire macula is little larger than a single grain of rice but is responsible for the central part of your vision. The macula provides much of the sharpness, fine detail and colour for your vision. This is because the macula has a very high concentration of photoreceptor cells. These cells are able to detect individual pulses of light and convert them into electrical signals that then travel into the complex retinal processing layers before being sent down to the optic nerve. The retina outside the macula area provides you with your peripheral vision – also called the visual field.
In this section we outline the different types of macular degeneration and the treatment options that can be considered for these conditions.
Broadly macular degeneration can be divided into:
- Dry Macular Degeneration
- Common Wet Macular Degeneration
- Uncommon Wet Macular Degeneration conditions
