方法：回顾性分析我院2009-01/2012-11收治的有反复发作的局部眼红眼痛的症状及体征的非金属球壁异物患者15例15眼，全部为非急性期。进行数字化裂隙灯眼表照相，经过UBM检查确诊为巩膜异物，手术后证实为非金属异物。

结果：有明确的植物眼外伤史10例10眼，病史不详5例5眼。病程1～6mo，均表现局部反复出现的眼红眼痛，药物治疗好转，停药后再次发作。裂隙灯下见局部的隆起，轻或重的充血，角膜无水肿。UBM检查见结膜下巩膜有高密度影，其后组织不显影声影，诊断：巩膜可疑异物。术后取出异物，11例11眼为植物异物，2例2眼为煤渣样异物，1例1眼为玻璃异物，1例1眼为石子异物。

结论：超声生物显微镜能及时、尽早发现非金属巩膜异物，减少误诊。针对巩膜长期局部反复充血的患者，无论有无外伤史，均应应用UBM检查有否巩膜异物的存在。

METHODS: Retrospective study of 15 patients who were diagnosed as scleral no-metallic foreign bodies. Their symptoms were repeated red-eye and eye-pain. All of them were in no-acute period. UBM were used to diagnose suspicious sclera foreign bodies, and were confirmed as no-metallic foreign bodies by surgical operation.

RESULTS: Medical history of 10 cases confirmed definitely botanical ocular trauma. Medical history of 5 cases was unidentified. Course of disease was 1-6 months. Clinical manifestations were repeatedly red-eye and eye-pain, which could be improved by medical treatment, but appeared once again after ceased medication. All patients presented with local rise in sclera, and lightly or heavy hyperemia without cornea edema. Ultrasound imaging was high-density imaging with the later tissue no imaging. Suspicious scleral foreign bodies were diagnosed. After operation, 11 cases were planted foreign bodies, 2 cases were coal cinder, 1 case was glass bits, 1 case was small stone.

CONCLUSION: UBM could find scleral no-metallic foreign bodies without delay,decrease.
