What is the wing in the eye?
A:
In fact, this problem is called pterygium, which is a chronic inflammatory disease. The main manifestation is that on the surface of our bulbar conjunctiva, a layer of fibrous vascular membrane will grow out of the white eyeballs, which will grow into the middle of the cornea in a triangular shape. Because it looks like an insect’s wings in appearance, it is called pterygium. Traditional Chinese medicine used to be called “Phymal Supplementing Eyes”. There is also a saying called “fish”. Of course, there are some patients who may mistakenly think that they are cataracts, but they are not.
Q:
Who are more likely to get pterygium?
A:
The cause of pterygium disease may be related to frequent exposure to ultraviolet light. Therefore, it may be frequent outdoor activities, outdoor enthusiasts, and some, that is, farmers may be more common, so there are some fishers. , This kind is more common
Q:
What are the hazards of pterygium?
A:
Mainly include, one is the appearance, because it has more fibrous blood vessels, it looks red in appearance, and the patient will respond to eye congestion. When it becomes inflamed, it will cause the discomfort of foreign body and tearing. Another thing is that there are more and more people who love beauty now, especially young people. With long wings on his eyes, he will feel that it affects his appearance. . There are also some, when they are relatively large, it will also restrict the movement of the eyeballs, and even some people will have double vision when they see things.
Q:
Does pterygium affect vision?
A:
The impact on vision depends on the size of the pterygium. If the pterygium is still relatively small, it may not necessarily affect the vision. If it grows to a certain size, it will cause a certain degree of corneal astigmatism. At this time, it may affect the vision, then even if it grows larger, it may cover the pupil. In this case, it will affect the vision.
Q:
Can pterygium be treated with medication?
A:
It also depends on the stage of his development. If it does not affect the vision, for example, when it is relatively small, it only affects the appearance. Then the eyes will be prone to redness, sometimes some foreign body sensation, uncomfortable feeling, then this Sometimes it can be treated with drugs to relieve symptoms. When it grows to a certain extent, it will grow to the middle, or when it grows larger and affects vision, then surgery may be considered in this case. Up.
Q:
What problems should be paid attention to before and after the operation of pterygium?
A:
For pterygium, under which conditions may need to be operated, then the first possibility is re-visibility. I just mentioned that it affects vision, that is, it covers the pupil. In this case, we call it re-visibility. Surgery, this kind of operation is to be done. The second type of choice, if the pterygium is also larger, it may cause a certain degree of corneal astigmatism. When some people have cataracts, if you do not remove the pterygium first, it may affect the degree of the lens. There is another type of measurement that is actually affected by the appearance just mentioned. Then there are more young people like him, and he will choose to have surgery. If you still need to pay attention before surgery, he must consider it carefully. Some older people may need to control their blood pressure and blood sugar better. Then there are some lesbians who are in menstrual periods and so on, she might best avoid them. Because surgery during that menstrual period may be easier to bleed a little. During the operation, the patient is mainly asked to cooperate well, because his pterygium is on one side, and the operation may have to turn his eyes to the opposite side. In this case, the operation will be better. Of course, in this case, doctors and nurses usually have explanations before and after the operation. After the operation, the main reason is to review regularly. Because of the medication, some thread irritation may need to be dealt with in time.
Q:
Is it easy to relapse after pterygium surgery?
A:
Pterygium surgery, the recurrence rate was relatively high in the past, so we usually encounter patients, many patients may even relapse, but the previous recurrence is relatively high, which may be 10%-20% about. So what are the reasons for this? One may be the problem of the choice of the surgical method. Another problem is that he did not cooperate with a certain review after the operation. Like the previous operation, maybe he just said to cut off, simply do pterygium resection, then the recurrence is relatively high. So the current standard for pterygium surgery should be pterygium resection combined with autologous conjunctival transplantation, or amniotic membrane transplantation, so this recurrence rate can be controlled very low. This recurrence rate should be reduced to less than 1%, so there is basically no need to worry about the recurrence rate of pterygium surgery.
Q:
How to prevent pterygium in life?
A:
As I mentioned earlier, it may be related to too much UV exposure. That is to say, especially the pterygium, it is found that there is a tendency to grow pterygium, if we find that there is a palpebral fissure. Then this may develop into pterygium, if some of our patients see that there is fibrous blood vessel growth. It should be noted that when you go outdoors, you may have to wear a hat or sunglasses, that is, take precautions when the ultraviolet rays are strong. If you do get more ultraviolet rays, your eyes will start to become a little irritated. Using some drugs, for example, some hormones and the like, can still control inflammation.
