What is macular degeneration?
Macular degeneration is one of the most common causes of specific vision loss in people aged 50 and above. It occurs when the macula in the retina becomes damaged, and the macula is the part responsible for central vision. The condition is divided into two types:
Dry macular degeneration: This is the most common type, where vision loss occurs slowly and gradually. It has no clear cause and happens when the light-sensitive cells break down over time.
Wet macular degeneration: This occurs when blood vessels begin to grow abnormally under the retina, leading to leakage of fluid and blood.
What are the symptoms of macular degeneration?
Most people do not show symptoms early on, and signs usually appear in later stages. However, you may notice:
Difficulty seeing in dim light.
Blurred vision.
Problems or changes in how colors appear.
Weak vision.
Straight edges of objects appearing wavy or curved.
Seeing empty spots or dark patches in your field of vision.
What causes macular degeneration?
The cause depends on the type, but most of the causes may be related to:
Genetics
Diabetes
Head injuries.
Infections.
A diet lacking essential nutrients.
The likelihood of developing it may increase when:
You are 50 or older.
You have a family history of macular degeneration.
You are overweight.
You smoke.
You have high blood pressure.
You follow a high-fat diet.
How is it diagnosed?
The doctor will take your medical history and perform a clinical examination. Additional tests may be requested as needed, such as:
Dilated eye exam: The doctor uses drops to widen the pupils.
Amsler grid test: To detect changes in central vision.
Fluorescein dye imaging.
Optical coherence tomography (OCT).
How is macular degeneration treated?
There is currently no treatment for dry macular degeneration, but some dietary supplements may help slow the progression of the disease, such as vitamin C, zinc, and copper. For wet macular degeneration, treatment involves various procedures as needed, which may include:
Anti-VEGF injections, administered in the clinic by a doctor.
Laser therapy.
How can macular degeneration be prevented?
There is no definite way to prevent the disease, but the risk can be reduced by:
Quitting smoking.
Following a healthy, balanced diet.
Maintaining normal blood pressure and cholesterol levels.
What are the complications of macular degeneration?
Macular degeneration can lead to severe loss of central vision, affecting your daily life and making it difficult to perform everyday tasks.
When should you see a doctor?
You should see a doctor if you experience:
Seeing floaters.
Seeing flashes of light.
Inflammation of the iris.
Severe eye pain.
Light sensitivity.
Frequently Asked Questions (FAQ):
Does macular degeneration cause total blindness?
No, it does not cause total vision loss. It only affects central vision, while peripheral vision remains unaffected.
