Age-related macular degeneration (AMD) is a common eye condition associated with the progressive deterioration of the macula. The macula is a part of the eye’s retina that’s responsible for central vision. AMD has two major types: wet and dry.
Read on as Clear View Vision Care, your reliable optometry center when it comes to dry eyes and other eye care problems, talks about AMD classifications in detail.
Approximately 90% of AMD cases are classified as dry. This occurs when the layers of the macula gradually shrink, compromising macular functions. During the early phase, you may experience changes in how you see colors. Yellow deposits may also form on your retina, known as drusen. These are the waste products of the eye’s cells. As the macula further thins and dries out, you may notice problems in your vision.
We advise eating dark, leafy greens, like kale. They are rich in certain antioxidants, lutein and zeaxanthin, which help maintain your eye cells and tissues. Eating fish high in omega-3 essential fatty acids is also advisable, as these promote eye health. Regular eye exams are a must, as well. Having your eyes checked allows us to monitor any changes in your condition, giving us the opportunity to provide necessary treatment.
Although this type only accounts for 10% of reported AMD cases, wet AMD is associated with severe vision loss. In this type, new blood vessels form in your eyes, which is why it’s also referred to as neovascular or exudative AMD. The fragile nature of the new blood vessels, however, causes them to rupture easily, causing fluid and blood to leak into the retina.
As a result, your macula may swell, causing it to rise from its normally flat position. This may gradually compromise your central vision. You may see dark spots across your visual field because of the blood deposits. Straight lines may look wavy, as well. With the wet type of macular degeneration, sudden onset of blindness is also common, which is why it’s considered a medical emergency. We may administer medications to suppress the growth of new blood vessels. Surgery may be needed to stop the blood leaks.
