摘要

背景:高分辨率超声(USG)提供了眼后段良好的解剖细节,描绘了影响眼后段的各种病理情况,有助于眼科医生选择最佳治疗方案。本研究旨在探讨高分辨率超声在眼后段病变诊断中的应用。材料和方法:一项以医院为基础的回顾性研究,纳入了一家三级医院的81例患者。行临床及眼科检查,眼眶超声检查。b模式USG采用7.5-13 MHz线性探头。最终的诊断是通过USG结果与临床和眼科检查相关联。统计学分析:采用卡方检验将b超USG的敏感性、特异性、阳性预测值、阴性预测值、准确性与眼科检查结果进行比较。结果:81例患者(男48例,女33例,平均年龄38.98±16.48 [SD]岁)中,有27例(33.3%)患者伴有白内障后段病变,14例(51.9%)患者有后玻璃体脱离(PVD), 10例(37%)患者有视网膜脱离(RD), 1例(3.7%)患者有脉络膜脱离(CD)。钝性眼损伤17例(21%)患者发现后段眼部病变,PVD 8例(47.1%),RD 4例(23.5%),CD 4例(23.5%)。眼部USG的敏感性为87.32%,特异性为80%,准确性为86.42%,USG与眼科诊断后段眼部异常的差异有统计学意义(p值为0.0005)。结论:高分辨率超声是评估眼后段病变的最佳且容易获得的成像方式之一,特别是在存在不透明眼介质的情况下。

Utility of High-Resolution Ultrasonography in the Evaluation of Posterior Segment Ocular Lesions Using Sensitivity and Specificity
Background: High-resolution Ultrasound (USG) provides good anatomical details of the ocular posterior segment and depicts the various pathological conditions affecting the ocular posterior segment, which helps ophthalmologists for choosing the best treatment options. This study aims to evaluate the utility of High-resolution Ultrasonography in the Evaluation of Posterior Segment Ocular lesions by using Sensitivity and Specificity.Materials and Methods: A hospital-based retrospective study enrolled 81 patients in a tertiary care hospital. Clinical and ophthalmological examinations were performed followed by USG of the orbits. B-mode USG was done with a 7.5–13 MHz linear probe. The final diagnosis was made by correlating the USG findings with clinical and ophthalmological examinations.Statistical analysis: Sensitivity, specificity, the positive predictive value, the negative predictive value, and the accuracy of B-scan USG were compared with the ophthalmological findings by using the Chi-square test.Results: Of 81 patients (n=48 males and n=33 females) with a mean age of 38.98 ± 16.48 [SD] years, posterior segment ocular lesions in association with cataracts were found in 27 (33.3%) patients, whereas 14 (51.9%) patients had posterior vitreous detachment (PVD), 10 (37%) patients had retinal detachment (RD), and 1 (3.7%) patient had choroidal detachment (CD). Posterior segment ocular pathologies were found in 17 (21%) patients with blunt ocular injuries, whereas 8 (47.1%) patients had PVD, 4 (23.5%) patients had RD and 4 (23.5%) patients had CD. The ocular USG had a sensitivity of 87.32%, specificity of 80%, and accuracy of 86.42% with a statistically significant difference between the USG findings and the Ophthalmology diagnosis of the posterior segment ocular abnormalities of a p-value of 0.0005.Conclusion: High-resolution ultrasound is one of the best and an easily available imaging modality for the evaluation of posterior segment ocular pathologies, especially in the presence of opaque ocular media.
