巩膜外加压及放液术:适合于球形脱离、网膜下积液较多者,陈旧性视网膜脱离、裂孔处脉络膜显著萎缩者,黄斑裂孔伴巩膜后葡萄肿者及有新裂孔的复发性网脱。
环扎术:环扎造成*性网膜条嵴。应用于多发性视网膜裂孔;视网膜脱离复发伴巩膜脆烂者;脉络膜显著萎缩的视网膜脱离者;玻璃体局限性或广泛性浓缩性萎缩者;视网膜有固定皱褶,即膜形成Ⅱ或Ⅲ级;视网膜大范围变性;无晶体眼及无裂孔视网膜脱离者。
环扎+巩膜外加压术:适用于较严重玻璃体牵引,广泛视网膜病变如Ⅱ或Ⅲ级膜形成;巨大裂孔;鱼嘴样裂孔;牵引性裂孔;大马蹄形裂孔;后极部裂孔;环扎时裂孔不在环扎带上等。网膜下积液多时应放液。
环扎+玻璃体条索剪断术:球内异物引起玻璃体条索牵拉发生的网脱,剪断玻璃体条索,使其游离后,再做环扎及放液。
巩膜层间填充术:一般用于视网膜浅脱离或不脱离的较大裂孔及后极部裂孔。玻璃体切割术:复杂性视网膜脱离,Ⅲ级膜形成,漏斗状网膜脱离,后极部固定皱褶,屈光间质混浊,网膜翻转的巨大裂孔或裂孔大于180°,黄斑及后极部较大裂孔,严重穿孔伤后网膜脱离等。
激光光凝术:适用范围 a.巩膜环扎或巩膜外加压术后视网膜局限脱离并视网膜裂孔封闭不全者;b.黄斑或后极部裂孔注气术后视网膜有浅脱离者;c.玻璃体切割术后视网膜再脱离者;d.视网膜浅脱离未手术者。
对轻度视网膜脱离者,可在裂孔周围光凝1~4排,形成视网膜脱离周围的光凝点包绕。以后重复光凝两三次,直至裂孔封闭。若不能包绕的,可在视网膜脱离后缘施以堤坝状光凝。
视网膜脱离复位手术失败的原因有哪些?
视网膜脱离复位手术失败是临床上经常遇到的一个难题。手术失败的原因很多,主要有以下几点:
(1)未加压到裂孔:未封闭的裂孔可能是不合并视网膜周边膜的网膜脱离手术失败的原因。网膜裂孔可能在术前检查未被发现。因此孔源性视网膜脱离强调反复多次寻找裂孔,对可疑存在裂孔网膜变性灶术中应予特别处理。也有新鲜裂孔引起术后失败的,但极其罕见。另一种情况是术中漏封了裂孔,所以术前检查结果应详细绘图,以便术中参考。
Scleral buckling and draining surgery: suitable for spherical detachment, subretinal fluid more who, old retinal detachment, significant atrophy of the choroid at the hole, macular hole with posterior staphyloma and recurrence of a new hole Net off.
Cerclage: Cerclage resulting in a permanent omentum ridge. Retinal detachment associated with scleral rupture; Significant atrophy of the choroid retinal detachment; Vitreous limited or extensive atrophy; Retina has a fixed fold, the formation of membrane grade II or III; the retina A wide range of degeneration; no crystalline eye and no retinal detachment.
Cerclage + external sclera compression surgery: for more severe vitreous traction, a wide range of retinopathy, such as Ⅱ or Ⅲ grade membrane formation; huge hole; fish mouth-like fracture; Traction Holes; large horseshoe-shaped hole; Holes when the ring is not on the ring and so on. Subretinal effusion should be drained for a long time.
Cerclage + vitreoretinal clipping: intraocular foreign body caused by pulling the vitreous cords pull off the network, cut the vitreous cord, make it free, do cerclage and drain.
Scleral interfacial filling: generally used for shallow retinal detachment or non-detachment from the larger holes and posterior pole hiatus. Vitrectomy: complex retinal detachment, grade III membrane formation, funnel-shaped retinal detachment, posterior pole fixation of folds, refractive mesenchymal opacity, large omentum fissures or fissures greater than 180 °, macular and posterior pole Larger hiatus, severe perforation injury after perforation and so on.
Laser photocoagulation: the scope of a. Scleral cerclage or scleral buckling after retinal detachment and retinal detachment insufficiency; b. Macular or posterior pole hiatus after retinal detachment were shallow; c. Vitreous Retinal retinal detachment after surgery; d retinal detachment without surgery.
For mild retinal detachment, photocoagulation can be around the hole 1 to 4 rows, forming retinal detachment around the photocoagulation point. After repeated photocoagulation two or three times, until the hole closed. If not wrapped around the retina can be applied to the posterior edge of the dam-like photocoagulation.

Retina detachment surgery failed to restore what are the reasons?
Retinal detachment surgery failure is a recurring clinical problems. The reasons for the failure of surgery are many, mainly in the following points:
(1) Uncompromised to open fissures: Unclosed fissures may be the cause of unsuccessful surgical failure of the retinal detachment without peri-retinal detachment. Omental tears may not be found in preoperative examination. Therefore, rhegmatogenous retinal detachment emphasizes repeatedly looking for the hole, the presence of suspected meshoptic degeneration surgery should be special treatment. There are also fresh holes caused postoperative failure, but extremely rare. Another case is the surgery leak hole, so the preoperative examination results should be detailed drawing, so that intraoperative reference.
