超声显像诊断在玻璃体切除术前选择适应症、以及术后随访观察起着重要作用,尤其玻璃体混浊的病例使用一般方法难以窥入,阻碍了玻璃体手术方法和手术时机的选择,而超声检查财不受屈光间质混浊的影响,依其超高频声束在组织内的传播和界面反射原理直接显示玻璃体病变的部位、形态、密度、范围、活动度,以及与视网膜的关系,为手术提供了十分有用的资料。本文对50例行玻璃体手术的病人进行了术前、术后的超声探查,现分析报道如下。
Ultrasound imaging in the selection of indications before vitrectomy and follow-up observation plays an important role, in particular, the use of the general method of vitreous opacity difficult to peep, hinder the choice of vitreous surgery methods and timing of surgery, and ultrasound examination of Choi Choi Not affected by refractive media opacity, according to its ultra-high frequency beam propagation in the tissue and interface reflection principle directly shows the location of vitreous lesions, morphology, density, range, activity, and the relationship with the retina, providing surgery Very useful information. In this paper, 50 cases of vitreous surgery patients underwent preoperative and postoperative ultrasound probe, the analysis is reported as follows.
