The poet said: "The night gave me black eyes, but I used them to look for light." But in the eyes of some people, their eyes do not have this ability. In this world, some people have seen the colorful world, but now they only remain in their memories; some people were born and saw only darkness in front of them. In the field of science, there are also eye diseases that are currently incurable. What does the world look like in their eyes? Under the guidance of the Department of Physical Health and Art Education of the Ministry of Education, and jointly produced by Hunan Satellite TV, Mango TV, and People's Daily Video Client Vision, the third episode of the first eye health science documentary "The Story of the Eye" produced by Mango Bojing was released today (August 30 ) Simultaneously broadcast on Hunan Satellite TV and Mango TV at 19:30, we will continue to take you to understand science and pay attention to eye health.
Experience the world in the eyes of the blind. "Eye Story" reveals the irreversible blinding eye diseases
In the second episode of "Eye Story", the audience learned about eye diseases such as dry eye, conjunctivitis and cataract, and received professional treatment Finally, it can be cured. The third episode broadcast tonight will take you to understand those irreversible blinding eye diseases.
Is the world the same in the eyes of a blind person? How are their perceptions different from normal people? In "The Story of Eyes", I interviewed a visually impaired person who was permanently blind due to an accident the day after tomorrow. As time went by, what he saw in his eyes was not darkness, but a sense of emptiness facing the world. He had no feelings for anything. The imagination of things stays in childhood. Perhaps in the eyes of every blind person, there is a dream world that belongs to them.
The visual range of normal people's eyes is about 180 degrees, but there is a group of eye disease patients whose visual range may be only half of ours. This eye disease is glaucoma. The visual world of glaucoma patients is like a large screen that slowly closes from the periphery to the center. The shapes of these screens are different, some are large and some are small. The world in the eyes of each patient is slowly getting smaller in an irregular manner. If it is not detected and treated in time, the final result is blindness. By 2020, there will be about 76 million glaucoma patients in the world, and the number in China is 21 million. Glaucoma has become the second most common blindness disease in the world. However, there is no medical method that can cure glaucoma in the world. The only way to slow down the vision loss of glaucoma is through combined treatment, which is equivalent to putting a "brake" on glaucoma patients. Although it cannot restore vision, it can at least keep the eyes seeing. function.
According to data released by the International Diabetes Federation (IDF): the number of diabetic patients (20-79 years old) in my country has reached 140 million in 2021, ranking first in the world. do you know? Diabetes can cause various eye complications such as fundus retinopathy, cataracts, glaucoma, and ophthalmoplegia, and can lead to blindness in severe cases. In the eyes of patients with diabetic retinopathy, they can see moving bridges and twisted buildings. It is difficult for them to see the true appearance of things. Fortunately, retinopathy has made major breakthroughs in medical research in recent years, and can be improved through immediate discovery and treatment. Therefore, it is particularly important to raise public awareness of diabetic eye disease and establish awareness among diabetic patients of regular fundus examinations!
In the eyes of these eye disease patients, the world appears in an unfamiliar form. I hope this popular science film can give them optimistic confidence in fighting the disease.
Learn about the eyes from "The Story of the Eye": Do you know the secret of the cornea?
Another important eyeball tissue for the human eye to see is the cornea. Its thickness is only about 0.5-1.0 mm, but it has powerful functions. The collagen fibers in normal corneal tissue allow light to enter the eye with almost no obstruction and scattering, so the visual quality will be very good. The oxygen and air permeability of the cornea is very good, which makes it difficult for artificially cultured corneas to completely simulate the human cornea. Once the cornea is severely damaged, it cannot be repaired. Currently, the only option is to wait for another suitable cornea to be replaced.
Currently, the number of people who are blind due to corneal diseases in China is about 4 million. The number of corneas that the deceased are willing to donate is far from enough. Therefore, less than 10,000 patients have the opportunity to regain their sight through surgery every year. The scene of cornea donation and transplantation was also shown in "The Story of the Eye". At the same time, the program team actively cooperated with the Mango Charity Platform and the China Organ Transplantation Development Foundation to carry out the "Donate Light Action" to help more patients with damaged corneas find light. , lovingly supports the public welfare project of "Xinmiao Education Assistance for Transplantation Babies", providing educational charity support for children who are studying after organ transplantation.
According to experts, the technology of corneal transplant surgery is very mature and the success rate of the operation is extremely high. Under normal circumstances, the patient's vision will recover two months after the operation. However, corneal transplant surgery in children is more complicated and time-consuming than that in adults. many. With the continuous development of science and technology, a new concept has emerged in corneal transplant surgery, called corneal component transplantation. Simply put, replacing the damaged cornea will cause fewer problems than replacing the entire cornea, and it can also Make one cornea available for multiple people. Research on artificial cornea has not stopped now. I believe that one day, blindness due to corneal damage will become a thing of the past.
Eyes are the starting point to dreams. The advancement of science and technology has injected vitality into dark eyes, allowing more patients with eye diseases to regain their sight. Lock on Hunan Satellite TV and Mango TV's "Eye Story" at 19:30 today to learn about the correct way to protect your eyes.
