Treatment is mostly surgical! Once again, retinal detachment (mainly foraminogenic) is an ophthalmic emergency, with rapid development and serious damage to vision, so it should be treated as soon as possible! Specifically: 1. Pore-derived retinal detachment: must be operated, and as soon as possible! The purpose of surgery: to close the fissure, drain the subretinal fluid, reset the retina as soon as possible, and protect the visual function as much as possible. The key to surgery: find all the fissures and close the holes. Surgical modality: two types. External surgery: ring ligation and external compression. This surgery does not open the eye, but presses the retina topically from the outside of the eye to the inside, like pressing from the outside of a ping pong ball to depress the wall into it. The lacunae are then closed with external condensation. The advantages are that the eye is not cut open, there is little disturbance to the eye, there is no risk of intraocular infection; and the intraocular filling is not used in the procedure and does not have to be removed in another surgery. However, it is not successful in all cases. It is suitable for single lacunae, limited retinal detachment, and retinal detachment without intravitreal traction factors. Internal surgery: vitrectomy + retinal repair. This procedure involves making three holes in the wall of the eye, extending instruments into the eye, removing the vitreous first, closing the retinal fissure from inside the eye, and sucking out the subretinal fluid, and the retina is reset intraoperatively. Since the vitreous body cannot regenerate after removal and the retina takes some time to heal, intraocular fillers such as silicone oil or gas are injected into the eye at the end of the procedure. The advantage is the direct and accurate closure of the fissure during surgery. As microsurgical instruments and techniques become more and more advanced, this procedure is mastered by a wide range of retinal surgeons, making the surgical technique much better and the success rate grows. It should be said that this surgery is applicable to all kinds of complex retinal detachments. Of course, compared to the external surgery, vitrectomy is more disturbing to the eye and has more complications, and if silicone oil is injected, it has to be removed surgically at 3 months. 2. Retinal detachment by traction: surgery. Vitrectomy. 3.Exudative retinal detachment: medication and treatment of the original disease.
