TCM interpretation of senile cataract

Abstract: the cortex around the lens becomes turbid, and then gradually develops to the center. At this time, it is not easy to detect under the small pupil. After mydriasis, oblique illumination with electric light can see gray wheel like turbidity. Visual acuity decreased slightly, but the fundus can still be seen.

senile cataract mostly occurs in people over 50 years old. The elderly are characterized by vision loss or even blindness caused by lens opacity. It is one of the common diseases in the elderly. At the initial stage of cataract, vision gradually decreases, eyes are free of redness, swelling and pain, things are blurred, and I feel that there is a fixed black shape in front of me, in strip or dot shape; Or have the feeling of myopia; Especially in dark places, blurred vision will intensify. Most of them are sick with both eyes, but the severity is different. The pathogenesis of senile cataract is still not fully understood. Many people believe that it is caused by lens fiber sclerosis and dehydration. When the human body is aging, the lens fibers gradually harden, the nucleus contracts, and the equatorial cortex is pulled by the suspensory ligament, resulting in cracks between the peripheral lens fibers and lens opacity. It may also increase the osmotic pressure of aqueous humor due to aging, dehydrate the lens and become turbid.

the course of general senile cataract is divided into four stages: initial stage: the cortex around the lens becomes turbid, and then gradually develops to the center. At this time, it is not easy to detect under the small pupil. After mydriasis, oblique illumination with electric light can see gray wheel like turbidity. Visual acuity decreased slightly, but the fundus can still be seen. Immature stage: most of the lens is turbid, but there are still transparent areas. Gray white appears in the pupil area. When the flashlight shines obliquely, it can be seen that the iris shadow falls on the deep turbidity of the lens, showing a crescent shadow. At this time, the patient’s visual acuity decreased significantly and the fundus could not be seen clearly. Mature stage: complete opacity of lens. Oblique iris projection. The swelling subsided, the anterior chamber returned to normal, and the visual acuity decreased significantly. Only manual or only light perception could be distinguished. This stage is suitable for surgical treatment. Overripe stage: the lens cortex is dissolved and liquefied, milky white. The nucleus sinks and is brown in color. Because the capsule is fragile, it sometimes breaks under severe vibration, making the nucleus enter the anterior chamber or vitreous body. At this time, the operation should be carried out in time, otherwise it may be blind forever. The name of cataract in traditional Chinese medicine is named after the change of pupil color according to the different stages of the disease, including “silver cataract”, “round pannus cataract”, “floating pannus”, “heavy pannus”, “yellow heart cataract”, etc. Traditional Chinese medicine believes that “at the age of 50, the liver leaves begin to thin, the bile begins to decrease, and the eyes begin to be unknown”. Therefore, it is often treated with the method of Tonifying the liver and kidney. In recent years, traditional Chinese medicine has a further understanding of cataract, which leads to the loss of liver and kidney; There may also be spleen deficiency, weak Qi, no water and valley, lack of essence and blood, and loss of nourishment of God ointment; There are liver and kidney yin deficiency, damp heat accumulation, yin deficiency and damp heat attack. In the initial stage and edema stage, the application of the above treatment can generally delay the maturity of cataract, especially cortical cataract. The curative effect of Chengde Huangxin cataract in traditional Chinese medicine is not good. In mature stage, traditional Chinese medicine can use improved needle dialing cataract surgery to perform cataract extraction.
