Wet Macular Degeneration

DEFINITION

Wet macular degeneration occurs when new blood vessels grow abnormally, then flood the leak under the macula. Macula is the area where the light-sensitive cells with tightly wrapped in the center of the retina.

Many cases of wet macular degeneration is a continuation of dry macular degeneration. Early detection and treatment can reduce the effect it causes.




SYMPTOMS
Symptoms of wet macular degeneration include:

• The vision is distorted. For example, straight objects look like wavy or bent.
• Central vision deteriorated

• Reduction in the intensity or clarity of the color
• The image blurred or blind spot in vision
• The vision deteriorated rapidly
• Viewing hallucinations. For example, formed an unusual pattern, certain objects, animals or even faces. This is due to communication errors between the macula and the brain.

Your vision may be worse in only one eye in the first years. However, the disease can affect both eyes at a later date.


Causes & Risk Factors
Cause
Wet macular degeneration occurs when new blood vessels grow abnormally in the bottom of the choroid and the retina in the macular. Abnormal blood vessels are leaking and flooded with blood. Blood between the choroid and retina and macula affects the function of causing your vision is blurred. In addition, is the sight looks like a bumpy and the blind spots in your vision. If you experience this condition in one eye, then you can experience it in both eyes at a later date.

As with dry macular degeneration, wet macular degeneration is caused by decreased function of the exhaust system of the eye. Cells that are sensitive to light in the retina die and come together and affect the supply of nutrients to the retina. However, what triggers the growth of abnormal blood vessels that remain unexplained.

Retinal pigment epithelial detachment
Another form of wet macular degeneration is a retinal pigment epithelial detachment that occurs when fluid from the choroid and berkupul bocort between the inner cell layer. No vessel growth of abnormal cells during RPE affected. But the fluid under the RPE causes it to look like a bump under the macula.


Risk factors
Wet macular degeneration risk factors include:
• Aged between 60 years and over
• a family history of macular degeneration
• Women are more likely to develop this condition because of age women tend to be longer than men
• Smoking
• Obesity
• Iris-colored eyes
• Exposure to sunlight, including ultraviolet light
• Lack of nutrients to the eye
• Having condition cardiovascular disease


Prevention
You can prevent macular degeneration with:
• Eat foods that contain antioxidants
• Stop smoking
• Control your condition if you have high blood pressure or other cardiovascular disease
• Frequent train your eye to move it (eye exercise)
• Routine check of your eyes
