Vision plummeting, distortion of vision, frequent dark shadows in front of the eyes, flashing sensations in front of the eyes, etc., these are all high-risk signs of “big problems” in the eyes, because the “culprit” of these symptoms often lies in the occurrence of lesions in the fundus of the eye. 1, which groups of people are most “favored” by fundus disease? The cornea, iris, and lens in front of the eye are defined by ophthalmology as the anterior segment of the eye, while the vitreous, retina, and choroid in the back are defined as the posterior segment of the eye. The base of the posterior segment of the eye is called the fundus. The fundus consists of the retina, the blood vessels of the fundus, the optic nerve papillae, the optic nerve fibers, the macula on the retina, and the choroid behind the retina, and lesions in these areas are collectively referred to as fundus. “If the eye is compared to a camera, a lesion in the front of the eye is equivalent to a broken lens, and a fundus lesion is a problem with the negative. There are many types of fundus diseases, with complex causes, and they are difficult to treat.” The causes of fundus disease are related to systemic diseases, such as diabetes, kidney disease, and hypertension. The main danger of fundus disease to people is that it affects the ability to see and can cause blindness in severe cases. Retinal detachment, macular degeneration, diabetic retinopathy, neovascular glaucoma, retinal vein obstruction, and complex eye trauma are common fundus diseases. Distortion of vision: seeing things bigger, smaller or curved is an important symptom of fundus disease, often indicating lesions in the macula, the sharpest visual area of the fundus; floating black shadows in front of the eyes: severe cases often suggest vitreous clouding or hemorrhage; flashing sensation in front of the eyes; narrowing or deficiency of the visual field; color vision changes: such as color blindness, etc. In addition, it is important to remind the elderly that when diabetes, arteriosclerosis and other systemic diseases occur, they should not only focus on treating the original disease, but also ignore the easy complications of fundus disease, and should go to the ophthalmology department regularly to check whether there are fundus lesions, so as to take early precautions. Diabetic patients are one of the most favored groups of people with fundus disease, and these people need to regularly ‘visit’ two departments: one is the endocrinology department for treating diabetes; the other is ophthalmology, and they need to be reviewed regularly after treatment.” Yu Xiaoyi stressed. 2, vitreoretinal surgery is the treatment of fundus disease “magic weapon” because the fundus disease is more complex, so the treatment is more difficult, many patients often have to endure the torture of the disease, or even helplessly accept the cruel reality of blindness. “In the past, the traditional method of treating fundus disease appeared to be somewhat ‘clumsy’, as it was difficult to visualize the condition of the fundus, so slightly complex fundus disease would give doctors a headache.” With the use of vitreoretinal surgery, especially with the improvements and developments of recent years, the success rate of fundus surgery has increased significantly, allowing surgery to achieve both cure or control of fundus disease and, more importantly, to give some otherwise untreatable and serious fundus disease a chance to restore light. For example, in severe fundus trauma, vitreoretinal surgery can accurately remove foreign bodies under direct vision, avoiding blindness and minimizing damage to surrounding tissues. In addition, all conditions within the eye can be “scouted” at the same time to resolve other hidden problems, avoiding multiple surgeries that can damage the intraocular structures of the affected eye, reducing the patient’s hospitalization costs, and maximizing the restoration of visual function in the affected eye. Mr. Wu, 47, is the “beneficiary” of vitreoretinal surgery. In recent times, Mr. Wu’s vision “plummeted” and there were black shadows in his vision, he rushed to the hospital and was diagnosed with retinal branch vein obstruction vitreous hemorrhage, which is commonly known as a blockage of blood vessels in the eye, and the retina became edematous and congested due to lack of oxygen. He was treated with medication for more than 3 weeks, but his vision deteriorated. Then, he opted for vitreoretinal surgery. In cases like Mr. Wu’s, if surgery is not performed in time, it will lead to serious consequences in a short time, such as neovascular glaucoma and cataract, and even blindness. It is understood that vitreoretinal surgery is mainly used for: complex retinal detachment, severe eye trauma, diabetic retinopathy, retinal vein obstruction, etc. If vitreoretinal surgery is the “magic weapon” for treating fundus disease, then minimally invasive surgery is the “new weapon” for treating fundus disease. If vitreoretinal surgery is a “powerful weapon” for treating fundus disease, then minimally invasive surgery is a “new weapon” for treating fundus disease. According to the introduction, the most practical minimally invasive technology for treating fundus disease is 23G minimally invasive vitreoretinal surgery. The minimally invasive surgery incision is only 0.6mm, the operation time is short, there is almost no bleeding in the wound, no need to cut the conjunctiva, the post-operative recovery is fast, there are few complications, and the post-operative inflammatory reaction is almost non-existent, the patient’s foreign body sensation, pain, tearing and other irritation symptoms are extremely mild. Within the scope of indications, such as macular fissure, macular anterior membrane, vitreous blood accumulation, simple retinal detachment, traumatic vitreoretinopathy, diabetic retinopathy, hypertensive retinopathy, retinal vascular obstruction, macular edema, endophthalmitis, etc., 23G vitreoretinal surgery can achieve excellent treatment results. In addition, it is worth mentioning that Chinese herbal medicine is unique in the treatment of fundus disease. At present, more than 80% of the drugs used in the treatment of fundus disease at home and abroad are herbal medicines or natural plant extracts. Chinese medicine treatment can improve retinal microcirculation, stimulate optic cell activity and improve optic nerve function to a certain extent.
