Department of Ophthalmology, Beijing Tongren Hospital: Retinal detachment, where is the detachment? How dangerous is it?

Source: Optometry Lecture Expert: Liu Wu, Deputy Director of Beijing Tongren Hospital Eye Center What is retinal detachment? Retinal detachment is the separation of the neuroepithelial and pigment epithelial layers of the retina. There is a potential gap between the two layers, and the fluid retained in the gap after separation is called subretinal fluid. The detached part of the retina cannot perceive light stimuli, resulting in incomplete or missing images from the eye. What are the types of retinal detachment? There are many retinal classification methods. According to the pathogenesis, it can be divided into rhegmatogenous, traction and exudative retinal detachment. According to the extent of retinal detachment, it is divided into two types: partial and complete, and according to its etiology, it is divided into two types: primary and secondary. 1. Primary retinal detachment Primary retinal detachment, also known as rhegmatogenous retinal detachment, is when the fluid in the vitreous cavity enters the subretinal through the retinal hole, causing the separation of the neuroepithelium and the pigment epithelium. Such patients often have retinal degeneration, atrophy, thinning, or high myopia, vitreous liquefaction, detachment, concentration and adhesion to the retina due to certain factors such as high myopia and advanced age. 2. Secondary retinal detachment The cause of secondary retinal detachment is relatively clear, caused by other diseases of the eye or some systemic diseases, such as exudative retinitis, acute diffuse choroiditis, pregnancy-induced hypertension retinopathy, etc. A large amount of exudate accumulates under the retina, causing retinal detachment. After some ocular trauma or periretinal phlebitis vitreous hemorrhage, the organized and proliferating vitreous cords pull the retina down. Some choroidal tumors or subretinal parasites can push up the retina and cause retinal detachment. Systemic diseases such as diabetic vitreoretinopathy, detachment due to vitreous proliferation pulling on the retina. There are also retinal detachment caused by some special eye diseases, such as congenital choroidal defect, Marfan syndrome, etc., which are related to congenital dysplasia of the fundus. Q: I have retinal detachment in my left eye. I have had laser surgery in 2000. Now I feel that objects in my right eye are a little blurry. Is it possible for my right eye to have retinal detachment? Is there a better way to treat retinal detachment? A: I have done it in my left eye Laser surgery, the right eye is a little blurry now, it is recommended to go to the hospital for further examination, because one eye has retinal detachment and the other eye is indeed at risk of detachment. After a detailed examination, it can be determined whether this has happened. fall off. If the scope of retinal detachment is small, there are no clinical symptoms, and it can be controlled by laser. However, most patients with retinal detachment will have symptoms, and it is difficult to ensure the effect of laser treatment for symptomatic patients. It is best to go through surgery. The sooner you do it, the better the effect of vision recovery, so you must find it early. #Super Health Team##Physician Reports Super Energy Team##Health Science Qualifying Tournament#
