How macular degeneration will happen?
Inside the eye with a layer of very special retinal pigment Epithelium (RPE), macular degeneration is Influence this layer of cells eye diseases.
RPE is like a wall, the retina and choroid compartment open. Choroid retina is the main blood vessel network Network. The main function is to provide camp RPE retinal Support, and eliminate waste. At the same time, RPE also served points responsibility from the retina and choroid.
Early macular degeneration with the development of macular degeneration, retinal waste generated open RPE start under accumulation, the formation of point-like yellow, Called drusen.
- Normal retinal
- Retinal pigment epithelial cells
- Retinal pigment epithelium (RPE)
Early macular degeneration Glass film (Bruch’s membrane) Thickened, appears drusen.
Drusen is the first symptom of macular degeneration but is likely to occur also unknown. Therefore, you need to regular eye exams and the macula, which is very important. Optometrist or ophthalmologist optometry using special equipment, be able to see inside the eye to check for early symptoms of macular degeneration (drusen).
A few drusen usually does not cause visual symptoms. Similarly, not all people who appear drusen Vision will necessarily diminish. However, the presence of drusen increased in the later stages of macular degeneration Probability.
Late macular degeneration
Late symptoms of macular degeneration are the representative of vision loss due to RPE cell death, or cannot stop pulse a network of blood vessels under the retina film growth.
Dry macular degeneration
After the RPE cell death, which is located above the retinal cell death also led to the retina part of the “missing loss. “This is commonly referred to graphic atrophy or” dry “macular degeneration, dry macular degeneration development is lagging more slowly, gradually leading to vision loss. In all post-related macular degeneration cases, 33% are the dry type.
Part of the initial or dry macular degeneration in the future will develop wet type, it is a more ferocious eye.
because here, if the sudden change in vision, you need to consult an eye doctor emergency, it is vital that a point. Delay in treatment will only increase the risk of vision loss.
Wet macular degeneration
When RPE cells were unable to prevent blood vessels in the retina choroid When under growth would lead to wet macular degeneration. new the blood vessels called choroidal neovascularization (CNV).
Although the rapid growth of new blood vessels, but very fragile, blood tube liquid under the retina and blood from the blood vessel wall permeability Out and scarring, leading to vision loss.
This is the kind of eye diseases in the most serious symptoms, Australia each year about 21,000 new cases diagnosed appears. Regard force variation is usually very sudden and very serious.
Wet macular degeneration
The rapid expansion of blood vessels, resulting in RPE rupture Vigilance vision changes.
Any sudden changes in vision or develop symptoms should promptly tell the ophthalmologist without delay. reservation
See a doctor will not take more than a week. Early detection is the key to the preservation of wet macular degeneration vision.
The earlier the treatment, the greater the possibility of preservation of vision. Delay treatment of vision loss can only increase Possibilities.
You see suspicious symptoms or sudden vision changes, you can use the Amsler Grid for self-testing.
This is an essential tool. You should use the Amsler Grid detection observed daily. but,
This test does not replace regular eye exams and macula. Amsler Grid is about as detailed in paragraph
What incentive is macular degeneration?
Macular degeneration incentives from both genetic and environmental aspects. Age, family history, smoking, eating and living
Information is the incidence of risk factors. In Australia, people over the age of 50, one in seven people who have this eye
Disease symptoms. The frequency of occurrence increases with age. Macular degeneration is also often hereditary.
If the immediate family In the case of patients, the incidence probability is 50%. Since at least 70% of cases with genetic, and therefore
Macular degeneration patients should tell their siblings and children, and encourage them to check the eyes and macula.
Related studies also show that smokers suffer from macular degeneration chance of non-smokers three to four times, at the same time,
Compared with nonsmokers, smokers early average age of five to ten years. Suction specific genetic predisposition but will significantly increase the chances of smokers suffering from wet macular degeneration.
Why Eyes Need Nutrition?
Studies have shown that diets to reduce macular degeneration and alleviate the worsening plays an important role. Balanced and contain large amount of antioxidants, vitamins and other nutrients in a healthy diet to maintain your eye health.
Lutein and zeaxanthin are all beneficial to the quality of eye health important antioxidants. These two substances in healthy
The macula has a very high content, can help protect the eyes. Spinach and beets (Junda dishes) and other deep green Leafy vegetables contain these two ingredients, corn and pepper west natural yellow fruits and vegetables can also find To.
In addition, vitamin C, vitamin E, zinc, and selenium are important antioxidants help maintain the macula health.
Omega-3 fat acids on eye health also assumed an important role. all fish and shellfish contain omega-3, but salmon, mackerel the content of fish, anchovies and trout and another oily fish is relatively high.
With respect to the intake of high glycemic index (GI) carbohydrates higher proportion
People, low GI carbohydrate intake more people suffering from macular degeneration.
The risk is smaller. Low GI carbohydrates include fruits, vegetables,
Whole grain cereals and whole grain bread.
