After further retinal optical tomography (OCT) and fundus fluorescein angiography (FAG), it was found that she had macular degeneration when she was young. The doctor said that after three subsequent treatments, her vision can be restored to 0.6, and she is still continuing to follow up the treatment.
The doctor stressed, "Age-related macular degeneration is no longer a patent for the elderly! 」
Risk factors such as macular degeneration, three highs, air pollution and high myopia are all included.
The retina is located at the posterior pole of the eyeball. If the eyes are compared to a camera, the retina is like a camera negative. The retina itself has photosensitive nerve cells, and the macula is the most sensitive photosensitive area in the retina, which has accurate color vision and can help vision to see things clearly.
With the increase of age, the uneven density and distribution of photoreceptor nerve cells in the eye and the accumulation of metabolic waste lead to macular degeneration, which is generally considered to be related to age, race and physique. The doctor said that modern lifestyle and living environment also play an important role, so it can also be regarded as a new civilization disease.
Macular lesion is no longer the limitation of old age.
"High myopia is a risk factor for macular degeneration," the doctor pointed out. "The proportion of people with high myopia in Taiwan Province Province ranks among the top in the world. Research in National Taiwan University Hospital shows that the proportion of children with high myopia has increased significantly in recent years, which may make macular degeneration younger. 」
According to Gong Wei's research, smoking, PM2.5 air pollution, hypertension, hyperlipidemia, diabetes, overweight and cardiovascular diseases may also be related to macular degeneration.
See things distorted and shadowed, don't ignore the symptoms of macular degeneration!
Macular lesions are divided into "dry maculopathy" and "wet maculopathy". The doctor explained that dry macular degeneration is the deposition of some metabolic wastes in the macula; Wet macular degeneration is caused by abnormal neovascularization of choroid under macula. These abnormal neovascularization will cause macular edema and abnormal macular structure, which will cause visual distortion and deterioration. Therefore, when patients with wet macular degeneration see things, the straight line will become wavy or have a central visual field defect.
The doctor shared, "Generally, young people find macular degeneration earlier, because young people use more eyes, and when they find abnormal vision, they will go to the doctor for examination. Clinically, many elderly people wait until the end of large visual field defect or macular degeneration. The photoreceptor cells in macular area have shrunk, died and even formed scar tissue, which not only has a bad prognosis, but also may be at risk of blindness. 」
Timely diagnosis and early treatment of macular diseases
When macular degeneration is suspected, optical tomography (OCT) can be arranged to detect the macular condition. The doctor said that the thickness of macula is very thin, less than 300 microns under normal circumstances. OCT scans the retina by infrared rays, which can help us to understand the structure of macular area without using a developer, and can detect the distribution of blood vessels in macular area, judge the activity of neovascularization and whether there is bleeding or effusion. It can not only diagnose macular disease, but also diagnose macular disease.
After age-related macular degeneration is diagnosed, it is necessary to receive treatment as soon as possible to prevent vision deterioration. The doctor explained that the current treatment methods include intraocular injection of anti-VEGF, laser photocoagulation and PDT.
The doctor stressed, "if we can treat it earlier, the new blood vessels will not extend widely, bleed or form scar tissue." If the new blood vessels are treated early, the vision will be obviously improved, and irreversible vision loss or even blindness will be avoided! 」
Intimate reminder
To develop good eye habits and keep enough eye distance, rest for 5 ~ 10 minutes every 30 minutes. Doctors suggest that we should pay attention to protecting our eyes in our daily life and dim the brightness of the screen when using 3C products.
In order to detect macular degeneration early, the American Ophthalmology Association suggested using amsler grid for self-test every day, covering one eye in turn and staring at the center of the grid with uncovered eyes. Normally, you should see a straight line. If you see twisted, deformed and shadowed lines, it may be macular degeneration. Be sure to see a doctor as soon as possible.
Age-related macular degeneration is no longer a disease of the elderly. High myopia, smoking, air pollution, hypertension, hyperlipidemia, diabetes, overweight, etc. May increase the risk of macular degeneration. People with risk factors should remember to have their eyes checked regularly. Doctors appeal that the older you get, the higher the risk of macular degeneration. People over 50 years old should have regular checkups even if they have no symptoms. If you see something distorted, blurred or shadowed, you must see a doctor as soon as possible, so that you can make an early diagnosis and seize the opportunity for treatment!
