Recently, when I look at things with my eyes, there are always many dark shadows floating around. What is the reason?

1, if it is the elderly, it is cataract.

The lens in the eyes of ordinary people is transparent tissue. Once the lens is turbid for any reason, it is called cataract disease, so cataract is a disease that occurs on the lens in the eye. According to this point, any lens opacity can be called cataract, but when the lens opacity is light, it does not obviously affect vision, and it is not included in the cataract. According to years of investigation, cataract is the most common cause of blindness and visual disability. It is estimated that about 25% of human beings have cataracts. Fortunately, this is an eye disease that is easy to cure.

How to treat cataract?

The treatment of cataract can be divided into non-surgical treatment and surgical treatment. Non-surgical treatment: Cataract, phenytoin and other eye drops can be added in the early stage of cataract to control the development. Surgical treatment: The visual acuity of cataract is below 0.3. As long as the fundus is in good condition and the symptoms of systemic diseases are not obvious, surgical treatment is feasible.

How many surgical methods are there? At present, there are two commonly used surgical methods: one is extracapsular cataract extraction with a pair of glasses after operation; The other is the most advanced surgical method in the world: extracapsular cataract extraction+intraocular lens implantation; Normal vision can be restored immediately after operation. At present, our hospital has introduced the most advanced equipment and instruments in the world and has first-class ophthalmologists in China. The incision of cataract surgery is small, and the operation can be completed in 2 ~ 5 minutes by phacoemulsification. In our hospital, more than 8,000 cataract patients were implanted with intraocular lenses, which enabled them to see again. The postoperative visual acuity of more than 90% patients reached 65438 0.0.

Can the elderly do cataract surgery? People over 90 can have cataract surgery, regardless of age, as long as they are in good health. Because I can see the light again after operation, I feel comfortable and can prolong my life.

What are the drugs for early cataract treatment?

Generally, there are the following drugs to treat cataract: ① Nutritional supplements, such as Li Yanming and Colin Rosso. ② Drugs related to quinone theory, such as Catalin, Folklin, Bainaiting and Zhizhangning. ③ Antioxidant drugs, such as glutathione, thiophene and SOD. (4) Other types such as parotid hormone, nitrocellulose, Lu Shiming, etc.

Traditional Chinese medicine has a certain effect on improving the vision of some patients. Commonly used acupoints are Jingming, Houqiu, Zhuzhu, Fish Waist, Hegu, Zusanli and Sanyinjiao. Traditional Chinese medicine treatment is mainly based on systemic syndrome differentiation, and early cataract is mainly based on nourishing liver and kidney, and Qiju Dihuang Pill or Dendrobium luminous Pill is selected; The weak of spleen deficiency and qi were given the method of invigorating spleen and benefiting qi, and Buzhong Yiqi Decoction was selected. For patients with liver heat disturbance, clearing away heat and calming the liver, cinnamon powder is selected; Those with yin deficiency and damp heat should nourish yin and clear away heat, be lenient and promote diuresis, and choose Ganlu drink.

What are the methods of cataract surgery?

Commonly used cataract surgery methods include cataract extraction, cataract needle aspiration and cataract needle dialing. With the development of microsurgery, modern cataract extraction, intraocular lens implantation and phacoemulsification have appeared.

The traditional cataract extraction is to remove all the lens including the capsule, but not the posterior capsule.

Modern extracapsular cataract extraction is characterized by closed aspiration and perfusion of anterior chamber under operating microscope. Because the intact posterior lens capsule is preserved, it has many advantages compared with intracapsular extraction, such as reducing the chance of vitreous loss, thus reducing complications such as retinal tear and retinal detachment.

Phacoemulsification is an improved extracapsular cataract extraction, which is most suitable for young patients with soft lens nucleus, especially those under 40 and 50 years old, with normal corneal endothelium, normal anterior chamber depth, dilated pupils of more than 7mm and moderate nuclear hardness. The absolute contraindications of this operation are lens subluxation and corneal endothelial decompensation. Relative contraindications mainly depend on the operator's experience and skills, such as corneal endothelial degeneration, shallow anterior chamber, small pupil, lens sclerosis and so on.

Cataract needle aspiration is suitable for congenital or traumatic cataract without hard nucleus under 30 years old.

2. If you are young, you have vitreous opacity.

The reason is:

1. Uveitis, inflammatory exudates and inflammatory cells enter the vitreous body, forming gray dust, flocculent or massive turbidity.

2. Hemorrhage, caused by retinal phlebitis, vein occlusion, diabetes, hypertension, trauma or surgery, enters the vitreous body, and forms red, yellow, gray-white flaky or massive turbidity in the process of blood entry and absorption.

3. Pigment, trauma, uveitis, etc. Make pigment particles enter the vitreous body.

4. Parasites and their metabolites, intraocular tumors or tumors in other parts of the body cause turbidity.

5. Foreign bodies remain in vitreous after ocular trauma.

6. Vitreous fibrous tissue hyperplasia caused by eye trauma, hemorrhage and diabetes.

7. Vitreous degeneration is more common in the elderly and people with high myopia. Vitreous hyaluronic acid depolymerization liquefaction. Diabetes and hypercholesterolemia may have cholesterol crystals deposited in the vitreous body.

Treatment principle: actively treat the primary disease, such as controlling inflammation, and treating fundus bleeding diseases with laser or drugs. For patients with severe turbidity, long course of disease and fibroproliferative changes, vitrectomy can be done.
