Principle of retinal detachment: Retinal detachment is the separation of the neuroepithelial layer of the retina from the pigment epithelial layer. There is a potential gap between the two layers and the fluid trapped in the gap after separation is called subretinal fluid. According to the etiology, they can be categorized as foramen ovale, tractional and exudative retinal detachment. The detached part of the retina does not work properly and the brain receives incomplete or total absence of images from the eye. It is related to the condition of the retina itself, the condition of the vitreous body and the eye itself and even genetic factors. The disease is most common in middle-aged or elderly people, most have myopia, and both eyes may develop successively. Symptoms of retinal detachment: (1) Flying mosquitoes and flashes of light: the earliest to appear. It is actually a symptom of posterior vitreous detachment. Middle-aged and old people, especially patients with high myopia, should be alert to the possibility of retinal detachment when a large number of flying mosquitoes suddenly appear and a certain direction of continuous flash. (2) Center vision loss: retinal detachment in the posterior pole part, vision decreases sharply. When the peripheral part of the initial detachment, there is no effect or very little effect on the central vision. Again, the fundus should be examined in detail in high-risk patients with vision loss. (3) Deformation of vision: when the peripheral detachment spreads to the posterior pole or shallow detachment occurs at the posterior pole, there is deformation of vision in addition to a decrease in central vision. (4) Visual field defects: in retinal detachment, some sensitive patients can detect visual field defects. However, only the lower visual field defects have early diagnostic value. Retinal detachment treatment: The first is the traditional scleral ring ligation or scleral external compression, or known as exenteration surgery, for general retinal detachment. Those with old retinal detachments will not regain their vision even if the surgery is successful and the retina is reset. The second surgical method, i.e. vitrectomy and retinal reset combined surgery, is suitable for some complex retinal detachment, which can not be cured by general surgical methods only. The third is laser treatment, which can be used for the retinal tear that has not yet detached; the fourth is traditional Chinese medicine (TCM) treatment, which treats retinal detachment with four types of symptoms, namely, deficiency of the liver and kidney, dampness and flooding of the spleen and kidney, and deficiency of both qi and yin. The fourth is TCM treatment. Different types of retinal detachment are treated with different remedies. Retinal surgery recovery: 1, eye retinal detachment after laser surgery, note that we still need to frequently review, close cooperation, reading books, watching TV should be appropriate, pay attention to the combination of work and rest, to avoid overuse of the eyes, to ensure the quality of sleep; to prevent eye trauma, pay attention to the value and protection of eyesight has been restored. Do a good job to keep warm, prevent colds and coughs, when coughing or sneezing vigorously, the tongue should be held against the palate, to prevent patients from retinal detachment again; 2, eye retinal detachment after laser surgery, pay attention to increase the crude fiber food, eat more fresh vegetables, fruits and moderate amount of liver, etc., avoid smoking, prohibit the consumption of alcohol, eat less or do not eat stimulating food, keep the bowel movement, and encourage it to form the habit of regular bowel movement, avoiding Excessive force bowel movement, to ensure that the eyes recover sufficient nutrition and prevent the occurrence of retinal detachment again; 3, eye retinal detachment laser surgery, attention should be paid to the postoperative 3 months should be frequently to the hospital for review, appropriate oral neurotrophic drugs, such as vitamin B1, inosine, adenosine triphosphate and so on, is conducive to the recovery of the retinal function, 3 months should be regularly rechecked, such as the eyes of the flashing sensation or the flashing of the spark, should immediately go to the hospital to dilate the pupil to check the retina, and the eyes should be dilated to check the pupil. If there are flashes or sparks in front of your eyes, you should go to the hospital immediately to check the fundus with dilated pupils, in order to find out the site and degree of retinopathy at an early stage, and then treat it in time, so as to prevent retinal detachment from occurring again. 4. Some surgeons ask you to sleep on your back or side after surgery. This is because the silicone oil or gas that is filled during the surgery will hold the retina in place, allowing the retina to reset faster. Although there are those Vision Advantage eye supports available after surgery that can ease the pain of sleeping on your back and help you recover faster, it’s still important to pay more attention to your eye health in general. Maintaining a healthy mindset and protecting the health of your eyes is the only way to completely eliminate retinal detachment.
