With the continuous improvement of people’s living standards, people can study, work and live comfortably in an air-conditioned environment, whether in the hot summer or in the cold winter, but dry air in an air-conditioned room for a long time is very easy to get dry eyes.
Dry eye syndrome is a condition in which people can experience a foreign body sensation in both eyes, dryness, itching, easy fatigue, inability to tolerate a smoky environment, and some unexplainable discomfort. It is often misdiagnosed clinically as common conjunctivitis, which cannot be alleviated with a variety of anti-inflammatory eye drops, and is only diagnosed after dry eye testing. In recent years, the incidence of dry eye has been on the rise.
The main causes of the disease.
primary or secondary dryness”.
2, young people are generally caused by excessive evaporation of tears, such as: long time in air-conditioned rooms, dry air; or because of wearing corneal contact lenses for too long, disrupting the balance of the eye surface; or because of long time to look at the computer, reducing the number of transient eyes, ordinary people blink once every 5 ~ 10 seconds on average, and long time to look at the computer, due to mental concentration, sometimes more than 20 seconds blink once, so that the tear film on the front surface of the cornea soon The tear film on the anterior surface of the cornea is quickly ruptured and loses its protective effect.
Different treatment methods should be used for the etiology of the disease.
1. Etiological treatment.
(1) Young people should wear as few corneal contact lenses as possible; pay attention to more transient eyes when operating a computer, or take a break after a period of time to look into the distance; in an air-conditioned room, put a basin of water to increase the humidity of the air, and if necessary, use artificial tear drops.
(2) For patients with secondary dry eye, the primary disease (such as collagen system disease) should be actively treated, and when the primary disease improves, the symptoms of dry eye will be reduced. Patients with excessive tear evaporation can clean their eyelids and apply hot compresses.
2, alternative treatment of tear components: the best artificial tears are self-serum, but its source is limited. For severe patients artificial tears without preservatives should be used as much as possible.
3, preservation of tears: methods include wearing silicone eye shields, wet room lenses or diving goggles; tear pegs or tear peg closure; therapeutic corneal contact lenses.
4.Promote tear secretion: oral administration of Bixupine, Mao Guo Yun Xiang Xiang Yin or Neostigmine can promote tear secretion in some patients, but the efficacy is not certain.
5. Reduce evaporation and exposure: Because when reading a book, the lid fissure is exposed small; when gazing at a computer fluorescent screen, the lid fissure is exposed large. Therefore, those who are frequently gazing at the fluorescent screen should pay attention to blinking more often.
6.Submandibular gland transplantation, corneal rim stem cell transplantation: may bring good news for patients with severe dry eye.
7, Chinese medicine treatment: According to Chinese medicine, the liver opens the eyes. The five organs produce five fluids and the liver produces fluids for tears. Therefore, “Su Wen – Xuan Ming Wu Qi Chapter” says: “The five organs transform fluid …… liver into tears. The Yinhai Jingwei clearly states: “Tears are the fluid of the liver”. Tears have the function of moistening the eye pearl. The production and excretion of tears are related to the function of the liver. Tears run in an orderly manner and do not overflow, which is the result of the restraining effect of liver qi. If the liver blood is insufficient, there will be few tears, dry eyes, blurred vision or even night blindness. On the contrary, if the liver is dysfunctional and cannot control the tears, the tears will be like weeping, so the “Ling Shu – Nine Needles” says: “The liver is the master of weeping”.
Dry eyes are called “white astringency” and “Shen Shui will dry up” in Chinese medicine. Liver and kidney yin deficiency or internal heat burning, decoction of fluid, can cause a decrease in tears.
1, Chinese medicine eye drops: with pure fresh honey, plus sterile distilled water, autoclaved sterilized and made. or with snow pear juice, ground pear juice, chrysanthemum, yellow lily, honey and CMC.
2.Chinese herbal fumigation of eyes: wild chrysanthemum, Qinpi, Huangbai, peppermint, mulberry leaf, safflower, etc.
3, Chinese herbal spray: Chai Hu injection + saline or Fishoil injection + saline.
4.Acupuncture and acupressure. Acupuncture mechanism to be studied in the future.
5.Chinese herbal soup: nourish liver yin, nourish eyes and brighten eyes. Qiju Dihuang Tang is the main ingredient.
The formula: Chinese wolfberry, white chrysanthemum, dogwood, raw earth, poria, zedoary, peony skin, white yam, etc.
If the mouth is dry and less fluid, add Wu Wei Zi, Xuan Shen, Sha Shen, Chuan Shi Dendrobium, Mai Dong, Yu Zhu, Tian Tian Tian Fan, Ge Ge Gen, etc.
Modern pharmacological analysis: Lycium barbarum has immune active active ingredients, is a class of complex structure of the sugar suffix, its sugar chain part may be its main active structure to play immune activity.
The main component in Lycium barbarum: Lycium polysaccharide, with strong cytoprotective effect and immune activity, can activate T lymphocytes and B lymphocytes, to enhance cellular immunity, but also to enhance humoral immune function.
Carotene in the fresh fruit of Lycium can be transformed into VitA in human body, which can promote the synthesis or regeneration of retinal intraretinal optic violet and maintain normal vision.
