What are the signs of blindness when playing with mobile phones? These three methods can cure eye blindness
Eyes are very important to our life and work, especially modern people basically use computers to work. Often looking at computer screens is very harmful to our eyes! Do you know the cause of blindness? What are the signs of blindness? Let's take a look at the detailed introduction below.
What are the causes of blindness?
In addition to congenital blindness, there are many clinical reasons for cataracts large dildo , glaucoma, diabetes, hypertension, high myopia, drugs and various trauma.
1. Cataracts. Cataract is a curable eye disease. The clinical manifestation is that the patient cannot see, but can see shadows and light; glaucoma is an irreversible eye disease that cannot be cured in the advanced stage and is prone to lifelong blindness.
2. Diabetes. Diabetes is a common ocular complication in the past 10 years and can seriously damage vision. It is called diabetic retinopathy magic wands , or sugar network for short. Common ocular complications of diabetes are fundus hemorrhage, exudation and even vitreous hemorrhage my old ass , proliferation of new blood vessels and organized membranes in the eye. The most serious is retinal detachment. In diabetic patients, if their diet is out of control and their blood sugar is too high, eye complications will be aggravated.
3. glaucoma. Glaucoma can be divided into primary and secondary. The cause of primary glaucoma is unknown, and it is suspected that ocular structural variation, anterior chamber shallowness, angle narrowing, iris root dilation or synechia; secondary glaucoma is related to ophthalmia, eye bleeding, and traumatic lens dislocation. Bad habits in patients can induce potential eye disease attacks, such as glaucoma patients and prospective patients. If they are angry, angry, drink large amounts of water at one time remote vibrator , and stay in a dark room for a long time (such as watching movies and TV in a dark room for a long time), an acute attack of glaucoma can be induced.
4. Hypertension. Hypertension mainly causes fundus hemorrhage, which may also lead to blindness.
These three methods can cure eye blindness
1、TTT
This is a laser treatment method developed in recent years. It uses the heat energy generated by the semiconductor laser to act on abnormal new blood vessels through the pupil to achieve the purpose of treatment. The local temperature of TTT is lower than that of traditional laser condensation, which causes little damage to surrounding normal tissues. However, the local normal tissues of TTT are also damaged, and the critical point of irradiation time is difficult to control. TTT is also not suitable for treating lesions in the fovea.
2、pDT
A photosensitizer is injected into the bloodstream through a vein. When the drug circulates to the retina, a non-thermal laser is used to stimulate the photosensitizer for treatment, and then abnormal new blood vessels are destroyed. pDT is used to treat choroidal neovascularization caused by age-related macular degeneration, especially choroidal neovascularization with central depression. It is by far the laser treatment method with the least damage to normal tissue.
3. Laser photocoagulation
This is commonly called a laser and has been used clinically for several years. The heat energy generated by argon laser is generally used to block abnormal new blood vessels and leakage points in the macula area and reduce the generation of new blood vessels. Although the laser can effectively block blood vessel leaks and leaks, it cannot prevent the formation of new blood vessels; it is only suitable for treating foveal lesions in the center of the macula, which cannot be coagulated with laser.
