玻璃体视网膜膜又称增殖性玻璃体视网膜病变（PVR）。在视网膜脱离眼中大约30％有一定程度的膜形成。这种膜是细胞性无血管膜，可以在脱离视网膜的内面、外面或者玻璃体腔中见到。

视网膜前膜的收缩，可以导致裂孔变形、固定和视网膜皱褶。裂孔的变形及固定使术中定位及封洞困难，而皱褶的视网膜变得混浊及僵硬，以至很难与脉络膜紧密粘附。视网膜下膜容易发生在长期视网膜脱离者，可与视网膜前膜共同存在。网膜下膜形成后，可见到视网膜线，广泛分布时视网膜呈“晒衣杆”样外观，视盘周围的网膜下膜引起“抽荷包”样改变。这种膜的收缩，形成了切线牵引，松解十分困难，严重时导致全视网膜脱离，使视网膜缩短成板状。玻璃体腔内的纤维细胞膜，可出现在视网膜脱离之前或脱离之后，是增殖反应的一部分，这种膜对视网膜的牵引，可造成视网膜脱离，又常使视网膜脱离复位手术失败。

因此，玻璃体视网膜膜形成的有无、轻重，对视网膜脱离的形成、手术方式选择及预后均有着重要意义。视网膜脱离手术前除应仔细寻找裂孔外，尚需详细了解玻璃体与视网膜情况，根据膜的有无及等级，选择恰当的手术方式，并尽量减轻膜的牵引力或将膜切除，才能提高视网膜脱离手术的成功率。

视网膜脱离手术前为何要全面检查眼底？

视网膜脱离手术前眼底检查主要包括三个内容：视网膜脱离的详细情况、玻璃体情况、玻璃体与视网膜的关系。这些检查对手术方式的选择、预后的判定有重要意义。

（1）视网膜脱离情况：①黄斑受累：如黄斑未受累，手术应尽早进行，以免脱离范围扩大波及黄斑，损害中心视力。如黄斑已脱离，则向患者说明手术后中心视力不一定能恢复。 ②网膜脱离轮廓：预示着网膜裂孔的位置。如果视网膜脱离外形及网膜下液分布不能用发现的裂孔加以解释，那么肯定还有其他裂孔被遗漏。③视网膜裂孔：仔细寻找裂孔，根据裂孔大小及位置选择加压区的范围及加压物的放置。④周边视网膜变性区：视网膜裂孔大多位于变性区内或附近。对找不到裂孔的病例，将可疑变性区作裂孔处理。⑤视网膜下液：要注意观察网膜下液的深度（尤其是裂孔下方）及网膜下液的流动性，因为这涉及到术中是否需放液。

Vitreoretinal membrane, also known as proliferative vitreoretinopathy (PVR). About 30% of the retinal detachment has some degree of film formation. This membrane is a cellular, avascular membrane that can be seen on the inside, outside or in the vitreous chamber from the retina.

Retinal membrane contraction, can lead to deformation of the hole, fixation and retinal folds. Holes deformation and fixation of intraoperative positioning and closure of the hole difficult, and wrinkled retina becomes turbid and stiff, it is difficult to closely adhere with the choroid. Subretinal membrane prone to long-term retinal detachment, with the pre-retinal co-exist. After the formation of subretinal film, you can see the retina line, the retina was widely distributed in the "clothes rod" -like appearance, subretinal membrane around the optic disc caused by "pumping purse" -like changes. This contraction of the film, the formation of a tangential traction, release is very difficult, resulting in serious retinal detachment, the retina shortened into a plate. Intravitreal fiber cell membrane, may appear before or after retinal detachment, is part of the proliferative response, this film on the retina traction, can cause retinal detachment, and often the retinal detachment surgery failed.

Therefore, the presence of vitreoretinal membrane formation, severity, the formation of retinal detachment, surgical options and prognosis are of great significance. In addition to retinal detachment surgery should be carefully looking for the hole, you still need to learn more about the vitreous and the retina, according to the presence and absence of the membrane, select the appropriate surgical approach, and try to reduce the traction of the membrane or the membrane in order to improve retinal detachment surgery The success rate. The company is located in:

Retinal detachment surgery before why a comprehensive examination of the fundus?

Retinal detachment before the operation of the fundus examination mainly consists of three elements: the details of retinal detachment, the vitreous, the vitreous and the retina. These tests on the choice of surgical approach, the prognosis of the decision is of great significance.

(1) retinal detachment: ① macular involvement: If the macula is not involved, surgery should be carried out as soon as possible to avoid the spread of the scope of macular affected, damage to central vision. If the macula has been detached, then to the patient that the center of vision after surgery may not be able to recover. ② retinal detachment outline: indicating the location of retinal breaks. If the retinal detachment profile and subretinal fluid distribution can not be found with the hole to be explained, then there are certainly other holes were missed. ③ retinal hiatus: Carefully look for the hole, according to the size and location of the hole to select the pressure zone and the placement of pressurized material. ④ peripheral retinal degeneration area: most of the retinal breaks in or near the degeneration area. For cases in which no hiatus can be found, the suspicious degeneration area is treated as a hiatus. ⑤ subretinal fluid: pay attention to observe the depth of subretinal fluid (especially below the hole) and subretinal fluidity, because it involves the need for fluid during operation.
