在2100例视网膜脱离手术眼中有78眼(70人)为锯齿缘离断,发病率为3.71％。8例为双眼。其中67.1％有挫伤。单侧锯齿缘离断有挫伤史者46例(74.2％)、双侧有挫伤史者1例(12.5％)。锯齿缘离断范围大于90°的占大多数(85.7％)。由直接挫伤所致的锯齿缘离断多在鼻上方,常并发玻璃体基础部脱离。在颞下方的锯齿缘离断,外伤性者占30.2％,自发性者占69.8％。手术宜用巩膜缩短加阔肌膜填充垫压,如并发ⅢA或ⅢB膜形成则宜环扎加压。复位率为93.4％。文中讨论了手术中的并发症。
In 2100 eyes with retinal detachment, 78 eyes (70) were serrated and the incidence was 3.71%. 8 cases for both eyes. 67.1% of them were contused. 46 cases (74.2%) had a history of contusion on one side with serrated edge, and 1 case (12.5%) had bilateral contusion history. Serrated edge break off the range of more than 90 ° accounted for the majority (85.7%). Serrated by the direct bruise cut off more than the top of the nose, often complicated by the separation of the basal body. In the inferior temporal jagged off, traumatic accounted for 30.2%, 69.8% of spontaneous. Surgical sclera should be used to shorten the width of the sphincter filling cushion, such as concurrent Ⅲ A or Ⅲ B film formation should be cerclage pressure. The reset rate was 93.4%. The article discusses the complications in surgery.
