In the ophthalmology clinic, or patient consultation, many patients and friends have the problem of floating black shadows in front of their eyes, these symptoms of patients, often no effect on vision, but very distressed, more patients and friends worried about going blind, it is no wonder, there are only two human eyes, once blind, the beautiful world can not appreciate, in fact, ah, patients with this problem need not be nervous, but still need to find a good examination of the ophthalmologist, some cases The eye doctor’s explanation will make you feel better and solve your problems. There are many vitreous lesions, including vitreous degeneration in the elderly, hemorrhage in the retina or uvea that invades the vitreous, high myopia, embryonic cells or tissues that remain in the vitreous from birth, ocular trauma, posterior vitreous detachment, intraocular foreign bodies, parasites and tumors that lead to varying degrees of vitreous clouding. Common causes include: degenerative, inflammatory, hemorrhagic, traumatic, and systemic diseases. So what are the dangers? This requires an eye examination to first rule out retinal choroidal lesions, such as hemorrhage, degeneration, and fissures, and to see what kind of vitreous lesions are present and how severe the clouding is. The next step is targeted treatment. Western medicine: generally firstly, anti-inflammatory or hemostatic treatment for the cause, followed by the application of iodine preparations, hyaluronidase, urokinase or calcium agents to promote absorption: physical therapy using ultrashort wave, or ultrasound and sodium iodide iontophoresis. Chinese medicine: according to the patient’s constitution, symptoms and local conditions of Chinese medicine for flexible identification and use of drugs to treat vitreous turbidity has been generally recognized by the medical community. Combined Chinese and Western medicine treatment: Chinese medicine and Western medicine treatment combined with modern treatment means. It can reduce the adverse reactions caused by the use of Western medicine alone, shorten the course of treatment and improve the efficacy compared with the use of Western medicine alone, and Chinese medicine can also increase the route of administration of Chinese medicine with the help of modern technology, so the combination of Chinese and Western medicine in the treatment of vitreous opacities has a wide range of prospects for surgical treatment of more serious vitreous lesions, such as severe opacities, vitreous parasites, proliferative vitreoretinopathy, viable vitreous Vitrectomy can successfully cure such cases. Removal of the vitreous helps to restore vision. Intraoperative treatment such as retinal photocoagulation can be done to address the cause. Many vitreous turbidities are seen in young patients, and there are many adhesions between the posterior vitreous membrane and the retina, which need to be removed intraoperatively, but it is very difficult to separate the adhesions. The postoperative inflammatory response usually requires systemic immunosuppressive therapy. Optic nerve atrophy or retinal damage, especially macular cystoid edema, is the main cause of limited postoperative visual recovery. Therefore but, vitreous opacities due to simple degenerative vitreous lesions usually do not require surgery. Chinese medical treatment is recommended.
