The purpose of this study is to evaluate the accuracy of diagnostic ultrasonography in the preoperative evaluation of eyes with media opacity after penetrating ocular trauma and correlate the preoperative findings with ultimate visual outcome.
A retrospective comparison was made between the preoperative ultrasound diagnoses and the intraoperative findings in 46 eyes of 45 patients undergoing pars plana vitrectomy after penetrating ocular trauma associated with dense media opacities. The preoperative echographic findings were correlated with long-term visual and anatomic outcome.
Preoperative echography was both sensitive and specific in evaluating traumatized eyes for retinal detachment, intraocular foreign bodies, posterior scleral wounds, and hemorrhagic choroidal detachments. The overall anatomic success rate was 87% (40/46) with 48% (22/46) of eyes obtaining visual acuity of 20/200 or better after surgery. The visual prognosis was worse in those eyes in which preoperative echography detected retinal detachment, subretinal blood, massive choroidals, or posterior exit wounds.
Diagnostic echography is accurate and provides useful prognostic information in eyes with media opacity after penetrating ocular trauma.
本研究旨在评估诊断性超声检查在穿透性眼外伤后伴有介质混浊的眼部术前评估中的准确性，并将术前检查结果与最终视觉结果相关联。
对45例穿透性眼外伤伴致密介质混浊患者的46只眼进行了回顾性比较，比较了术前超声诊断与术中发现。将术前超声检查结果与长期视觉和解剖学结果相关联。
术前超声检查在评估受伤眼睛的视网膜脱离、眼内异物、巩膜后伤口和出血性脉络膜脱离方面既敏感又特异。总体解剖成功率为87%（40/46），48%（22/46）的眼睛术后视力达到20/200或更好。术前超声检查发现视网膜脱离、视网膜下出血、大量脉络膜病变或后出口伤口的眼睛，其视觉预后较差。
诊断性超声检查准确，可为穿透性眼外伤后伴有介质混浊的眼睛提供有用的预后信息。
