Introduction
Your eyes have a very special part called the macula. It helps you see things right in front of you, like reading a book or watching television. Have you ever noticed how you can see words clearly when you're reading? That is your macula at work! When someone gets age-related macular degeneration, this part stops working well, usually in people older than 50.
What happens if age-related macular degeneration is not caught early? If not identified, age-related macular degeneration can lead to vision problems and even cause loss of vision. That is why it is so important to detect and diagnose it as early as possible. There is no single specific treatment for age-related macular degeneration. Once it is confirmed, the goal of macular degeneration treatment is to slow down the condition and help prevent serious vision loss.
What Is AMD (Age-Related Macular Degeneration)?
It is an eye problem that usually happens to older people, especially those over 50 years old.
There is a small part in the back of your eye called the macula. It helps you see things clearly right in front of you, like when you are reading, looking at someone’s face, or watching TV.
When someone has this condition, the macula gets damaged.
This makes it hard for them to see things in the middle of their vision. It is like having a blurry or blank spot right where you are trying to look. In the beginning, people might not notice anything is wrong. But as it gets worse, they may not be able to read, drive a car, or recognize faces easily
There are two main types of age-related macular degeneration (AMD):
-
Dry AMD (The Common Kind): This type happens slowly over time. Small yellow spots form under the back part of the eye (the retina). These spots can make it harder to see clearly, especially when reading or seeing small details.
-
Wet AMD (The Serious Kind): This one is less common but more dangerous. Tiny, weak blood vessels grow under the retina. These vessels can leak blood or fluid, which can quickly damage vision and make it hard to see straight ahead.
How Is AMD Diagnosed?
-
Eye Tests - The eye specialist opens the eyelids wide using drops prior to examining the back of the eye with the aid of a special instrument. The ophthalmologist will be looking for a patchy appearance caused by Drusen, which are yellow spots that form on the retina.
-
Optical Coherence Tomography (OCT) - The retina is detailed in cross-section in this non-surgical imaging procedure. It reveals areas of the retina that could be thinned, thickened, or swollen. These can occur as a result of fluid buildup from leaks in and behind the retina's blood vessels.
-
Fluorescein Angiography - The ophthalmologist may inject a dye through an arm vein while doing this test. The dye travels into the eye and makes the blood vessels in the eye visible. A specialized camera takes several pictures while the dye goes through the blood vessels. The scans will show the retinal or blood vessel abnormalities, which are signs of macular degeneration.
-
Ultrasound Eye Examination - Ultrasound sends high-energy sound waves to scan the eye by producing echoes as they move through the inner tissues. A probe that both sends and receives the sound waves is placed on the surface of the eye softly after applying eye drops to anesthetize the eye. The echoes create a view inside the eyes.
What to Do Next After Being Diagnosed With Age-Related Macular Degeneration?
Some people with the dry type of age-related macular degeneration may later get the wet type, which is more serious. If you have the dry type now, it is important to check your vision regularly.
Here is what to do:
-
Check your vision once a week.
-
Test one eye at a time by covering the other eye.
-
Use an Amsler Grid Chart (a grid with straight lines).
-
You can print it and put it on your fridge, or use it on your computer or tablet.
-
If you notice wavy lines, blurry spots, or anything that looks different, tell your doctor.
1. If You Have the Wet Type:
-
Even if you have had treatment for the wet type, you still need to check your vision often.
-
Watch for new blind spots or if old ones are getting bigger.
-
New blood vessels can grow even months or years after treatment, so keep checking.
2. If Only One Eye Is Affected
If you only have macular degeneration in one eye, your doctor will check the other eye during regular eye exams to catch any new problems early.
What Are the Treatment Options for Age-Related Macular Degeneration?
The following are some of the treatment options for age-related macular degeneration.
-
Anti-angiogenic Drugs - Drugs for macular degeneration are Bevacizumab, Faricimab-svoa, Pegaptanib, and Ranibizumab. The drugs assist in inhibiting the development of blood vessels and the leakage from the vessels within the eye that results in wet macular degeneration.
-
Diet - Physicians may recommend that patients eat a healthy, antioxidant-rich diet consisting of salmon, dark leafy greens, and other foods that are good for the eyes, such as yellow fruits and vegetables.
-
Supplements - Based on the findings of a large study (age related eye disease study - AREDS), the precise combination of vitamins and nutrients can guard against eye disease in some patients with intermediate or late age-related macular degeneration. The supplements could help prevent intermediate age-related macular degeneration from advancing to more serious stages and maintain vision for some individuals.
-
Injections - Anti-vascular endothelial growth factor (VEGF) medication, which combats fluid accumulation in the macula, an area of the retina responsible for central vision and reading small print, decreases swelling, and the patient is given a steroid injection in the eye by the physician.
-
Laser Therapy - Laser closes off blood vessels that are near the macula by burning them. This prevents them from leaking, and they may not feel a lot of pain due to the lack of pain nerves in the retina.
-
Low Vision Aids - They are helpful tools for people with vision loss from age-related macular degeneration. These devices use special lenses or electronics to make things look bigger and easier to see. Examples include reading magnifiers, special eyeglasses, and electronic glasses.
-
Photodynamic Therapy - The doctor initially gives you some special medication through a needle in your arm, which travels to the abnormal blood vessels in your eye (for wet AMD). Second, a laser beam is flashed into your eye to activate the medicine, and this stops the blood vessels from leaking (as seen in AMD).
Conclusion
Some eye problems can make it hard to see things clearly in the center of your vision, like when you are reading, seeing faces, or looking straight ahead. This often happens to older people over the age of 50. The part of the eye that helps you see things in front of you is called the macula. If it gets damaged, it can be hard to do everyday things like reading or driving. At first, there might not be any signs, so people do not always know there is a problem. But if you or someone you know starts having trouble seeing clearly, it is a good idea to see an eye doctor. They can help keep your eyes healthy.
Note from iCliniq
