What is a modern vitreous surgery? July 26, 2004
Vitrectomy developed in the early 70's microsurgery. Its appearance is considered a revolution history of eye treatment, many previously incurable eye diseases that access to treatment. With the continuous improvement of surgical instruments and the accumulation of experience, expanding indications for surgery, ophthalmology centers in developed countries, cataract extraction after vitrectomy and intraocular lens implantation has become the second leading ophthalmic surgery. Modern indications for vitrectomy growing, not only to remove the vitreous cavity of the vitreous, but also forward removal of soft cataracts, pupillary membrane, into the anterior chamber of the lens, vitreous, blood; back the machine to remove compounds retinal surface . In addition to angular extent of surgery, scleral buckling, almost throughout the entire eye, so that in the past, many are not treated, can not even imagine the eye difficult disease to be healed. Vitrectomy indications what? (1) of the anterior segment Indications: soft cataracts: a more complete removal of vitrectomy lens cortex function, so that pupils receive completely transparent, without an after-cataract. pupil: pupil various causes can be removed. anterior segment perforating injury: perforation of the anterior segment injury with traumatic cataract, vitreous prolapse, especially when the wound was closed immediately after vitrectomy for the crystal and the former can improve vision and reduce the after-cataract and intraocular unit membrane. off in the anterior chamber crystals: Crystal removed without a hard pre-approved. vitreous with cornea syndrome: cataract surgery, if the vitreous into the anterior chamber through the pupil and corneal endothelial , can make corneal endothelial decompensation. Therefore, the vitreous into the anterior chamber should be fully removed. malignant glaucoma: removal of anterior vitreous, the lifting block drainage of aqueous forward, so that high intraocular pressure under control. (2) the posterior segment Indications: vitreous hemorrhage: is vitrectomy, a major indication. After conservative treatment of vitreous hemorrhage in 3 to 6 months does not absorb, it should be vitrectomy. But once observed retinal detachment surgery should be timely. Children to prevent amblyopia, general surgery should be as soon as possible. Surgery can be traumatic vitreous hemorrhage early. intraocular foreign bodies: vitrectomy foreign body is taken under direct vision, especially for non-magnetic foreign bodies, or when accompanied by other ocular tissue damage, easy to deal with. eye inflammation Content: surgery to clear the bacteria and their toxins, removal of necrotic tissue and inflammatory substances, and direct injection of drugs to the vitreous cavity. retinal detachment: vitreous opacities, a huge hole merger proliferative vitreoretinopathy, macular hole, vitreous traction caused by the proliferation of retinal detachment, diabetic retinopathy, retinal detachment caused by the situation, suitable for vitrectomy. Some also choose to recurrent retinal detachment vitrectomy. Others: lens dislocation into the vitreous; cataract surgery with debris falling into the vitreous body; macular pucker, macular epiretinal membrane and macular hole dry; intravitreal cysticercosis and other diseases, but also indications for vitrectomy. What vitrectomy for retinal detachment? Although the vast majority of conventional retinal detachment surgery as a way of patient selection, but the introduction of vitrectomy has greatly broadened the scope of cure. Vitrectomy, in some cases adapted to the initial surgery, not only after failure of conventional surgery to consider using, because each for an operation, the more poor visual prognosis. Retinal not see the situation: a number of reasons can cause turbidity and refractive pupil can not be opened just could not see the eyes, so the hole retinal detachment is unknown, treatment difficult. The B-and electrophysiological studies to determine with network off, and retinal function is good, vitrectomy should be to clear the haze refractive and safe to open large pupils, improve fundus observation, to improve visual acuity. Traction retinal detachment: often caused by ocular trauma and retinal vascular diseases. Vitrectomy is the best traction retinal detachment surgery. Surgery to lift the traction on the retina in all directions, cut, proliferation of vascular membrane separation, removal of epiretinal membrane. With the lifting of traction, the retina may be a good reset. Sometimes required for retinal incision, drainage and intraocular photocoagulation. Proliferative vitreoretinopathy retinal detachment: proliferative vitreoretinopathy retinal detachment surgery leading to failure of the main reasons. This disease often occurs in long-term, old retinal detachment, intraocular inflammation, retinal detachment associated with vitreous hemorrhage, a huge hole, multiple network failures or excessive reduction procedure for removal of retinal coagulation, condensation operation. These conditions should be vitrectomy, membrane peeling, intraocular fluid discharge, gas or silicone oil filled eyes, intraocular photocoagulation and scleral buckling surgery, if necessary, cut or removed as the retina to help reset the retinal release. Huge hole retinal detachment: a huge hole flap flip, giant retinal tear fixed, could be vitrectomy, membrane stripping to remove the vitreous traction on the retina. Necessary for gas or silicone oil tamponade and scleral layer compression technique. Stiffness or traction retinal posterior pole retinal detachment: the complexity of these nets off the disease, conventional surgery difficult to perform, easy to damage the optic nerve and macular. Can be combined with vitrectomy for treatment of gas or silicone oil tamponade. Recurrent retinal detachment: the network several times off the reset routine surgery or vitrectomy failed, leading to severe vitreoretinopathy, retinal folds and more fixed, retinal stiffness, weakened. Therefore required to be filled with vitrectomy and vitreous surgery combined scleral buckling. Why use vitrectomy eye laser surgery? Surgical indications for vitrectomy growing, thanks to improvements in technology, and some auxiliary equipment for a wide range of applications provide a reliable guarantee. The use of laser eye, so many complex retinal detachment and vitrectomy operation more simple and secure. (1) closed hole: the conventional retinal detachment surgery by condensation or coagulation closed hole. Ocular tissue damage, and easily generate proliferative vitreoretinopathy. Sealing is the use of laser eye under direct vision, high accuracy, reliable sealing, eye tissue damage, even without outside pressure for the sclera, or the filling between layers, simplifying the surgical procedure. (2) prevention of bleeding: the eye laser photocoagulation on retinal neovascularization bleeding may occur, reducing the possibility of bleeding. (3) retinal photocoagulation lesions: Many of proliferative retinopathy after the removal of proliferative membranes, with the corresponding region of intraocular retinal laser photocoagulation intensive, opportunities for reduction of postoperative vitreous hemorrhage and improve the success rate of surgery. (4) preventive photocoagulation: vitrectomy dangerous peripheral retinal degeneration found in kitchen when timely laser photocoagulation can prevent the occurrence of new retinal breaks. In the retinal detachment surgery for scleral buckling pressure, scleral encircling layer after filling or, if not well attached to that hole in the pressure ridge, can be used to add laser eye. Such as retinal incision, omental resection, removal of subretinal membrane and so operation of regional retinal photocoagulation in advance, to ensure the safety of surgical procedures. What are the complications of vitrectomy, how to prevent and deal with it? Vitrectomy sometimes produce some complications and the complications of surgery to prevention, in case, a timely treatment. Common complication of vitrectomy are the following. (1) corneal edema: often occurs in diabetic patients. Because diabetes reduces the density of corneal endothelial cells, if combined with crystal cut more likely, is generally self-limiting. (2) Cataract: Diabetes patients prone to cataracts, and sometimes simultaneous removal of cataracts. Perfusate of sometimes causing temporary lens opacities, the best use of glutathione - sodium bicarbonate - Ringer, not near the cutting head or the front of posterior capsular lens posterior capsule cut to avoid traumatic cataract. (3) vitreous incarceration: vitreous incarceration in the wound, can produce fibrous vascular membrane, the occurrence of vitreous traction. Incision should be complete removal of the vitreous that may exist. (4) vitreous hemorrhage: intraoperative and postoperative can cause. Bottles of blood loss can improve the perfusion fluid to increase perfusion pressure, but also under water coagulation; intraoperative and postoperative photocoagulation of lesions can prevent bleeding; postoperative bleeding can be self-absorbed most of the observed 3 to 6 months does not absorb may re-operation. (5) glaucoma: a common complication after surgery. For a moment, or edema caused by inflammation of the trabecular, drugs can control. If the ghost cell glaucoma, first with medication, can be used for stubborn cases of anterior chamber irrigation. Can also occur after surgery for neovascular glaucoma, drug therapy generally does not work, try filtering surgery or ciliary body cryotherapy. (6), retinal tear or retinal detachment: surgery in poor lighting, or organization a confusion, cutting head and appeal directly to the retina or vitreous traction and retinal adhesion can occur when the cable. Therefore, patients must have a good microscope and lenses, lighting should be adequate, the cutting head must be sharp, can not pull the cord. Recent application of low suction force of the retina cutting, high cutting rate. Intraoperative retinal breaks were found, with the eye for the prevention of laser photocoagulation. Can occur when the eye Wangmo from the laser or condensation sealing, vitreous gas injection, scleral buckling pressure, such as ring rolling approach. (7) endophthalmitis: rare. By conventional therapy. Also re-vitrectomy. (8), sympathetic ophthalmia: The incidence of other significant intraocular surgery. Symptomatic treatment. (9) ocular atrophy: occasionally occur. Silicone oil in vitreoretinal surgery what is the value, the use of silicone oil which will have side effects? Silicone oil is a good eye filler. Silicone oil transparent, refractive index 1.40, close to the water and vitreous, refractive surgery does not change the power and influence surgical operation, and there is help after photocoagulation; silicone oil has a certain viscosity, and surface tension, so the hole can be closed; expansion of non-silicone oil filling material, the chance of postoperative high intraocular pressure is small; silicone oil in the eye does not absorb, a long residence time within the eye; silicone oil also reduced the growth of epiretinal membrane and hemostasis. Intraoperative use of silicone oil in patients with supine position, patients do not have to take a special position. Because of these advantages of silicone oil in vitreoretinal surgery is widely used, common indications are: (1) proliferative vitreoretinopathy retinal detachment: This disease reduces the activity of the retina, prevent closed hole. Proliferation of silicone oil can ease the body of the traction on the retina, restoring the activity of the retina, which will help close holes. (2) a huge hole retinal detachment: in the implementation of vitreous surgery to reset flip flap, silicone oil tamponade is better than gas tamponade, the retina nails and other methods. (3) rigid posterior pole with retinal hole retinal detachment: silicone oil surgery in the supine position, after having stomach, silicone oil is better than the gas well. (4) proliferative diabetic retinopathy: often off the traction network, multiple holes, multiple neovascularization, retinal activity is poor, refractive media opacity, combined with vitrectomy and intraocular silicone oil could save part of the visual function of laser photocoagulation . (5), recurrent retinal detachment: After vitrectomy, gas tamponade failure surgery, silicone oil can be used to obtain a certain effect. However, intravitreal silicone oil injection may produce some complications such as cataracts. Silicone oil tamponade, the crystal must cloudy, affecting vision when the cataract extraction with intraocular lens implantation possible surgery. Some academics have also filled with silicone oil at the same time removal of a transparent crystal.
