Your retina and macula control your central vision. As you age, these eye structures can deteriorate, leading to age-related macular degeneration (AMD), one of the top causes of visual impairment and vision loss among adult Americans. Here, Downtown Eyes, your trusted vision care clinic, sheds light on this condition.
Types of AMD
There are two types of AMD: dry and wet. 80-90% of reported cases are dry AMD, which is also referred to as non-exudative or non-neovascular due to the absence of blood or fluid leaks. Dry AMD occurs when your macula’s layers gradually shrink, compromising its functionality. This can lead to eye waste buildup, also known as drusen formation, which may manifest as yellow deposits on your retina.
10% of the AMD cases are the wet type. Although less common, wet AMD deserves attention because it is associated with sudden onset of blindness. With this type of AMD, the blood vessels in your eyes become extremely fragile and eventually rupture, leaking blood, lipids, and other fluids into the retina. Our expert eye doctor explains that this causes the retina to swell, forcing the macula to stray from its original location as well.
Dry AMD often manifests with pigmentation abnormalities and can cause episodes of blurry central vision and limited peripheral and night vision. Wet AMD can involve extensive central vision impairment, distorted eyesight, and the presence of dark spots across your visual field.
Our Suggested Treatment
Visit your trusted eye doctor or optometrist immediately if you experience any of these symptoms. We will perform an optomap retinal exam so we can have a better view of your retina, which will enable us to determine whether you have AMD and which type you are experiencing. We will then create a treatment plan geared to your specific needs.
Eating foods rich in antioxidants and eye-friendly nutrients, like leafy greens, can help prevent the progression of AMD. We may prescribe certain medications to suppress abnormal blood vessel growth. Laser surgery is another option, as it can reduce blood vessel rupture or leaks in your eyes.
