■确定眼运动性测试对检测是否存在肌肉卡压的有用性。
■面部创伤继发复视症状患者的横断面研究。纳入标准:年龄在20至80岁之间;面部创伤后复视症状;放射学证实存在眶底骨折;手术时证实存在肌肉卡压;最佳矫正视力0.6或以上。排除标准:计算机断层扫描可见的肌肉卡压;立即手术矫正的候选人;斜视手术史。结果测量:头部位置异常(AHP),赫希伯格角膜反射(CR),盖板/揭开和交替盖板测试,赫特尔眼球测量,近收敛点(NPC),KestenbaumLimbus测试,红色滤光片测试,和Hess屏幕测试.
■46名受试者(38名男性,8位女性,平均年龄27±3.3SD年)。术前评估:46(100%)在RedFilter测试中报告了复视,并在HessScreen测试中显示了一定程度的异常。42例(91%)显示层次分析法。41例(89%)的眼球测量值在两只眼睛和NPC不足之间相差2mm或更多。在KestenbaumLimbus测试中,有32例(69.6%)显示出3毫米或更多的缺陷。16位(35%)的Hirschberg角膜反射异常。11例(24%)表现出恒定或间歇性斜视。
■眼球运动测试可以进行非侵入性区分,术前,并且即使在计算机断层扫描上看不到肌肉卡压的存在也具有成本效益。
UNASSIGNED: Determine the usefulness of ocular motility testing to detect the presence of muscle entrapment.
UNASSIGNED: Cross-sectional study of patients with symptoms of diplopia secondary to facial trauma. Inclusion criteria: age between 20 and 80 years; symptoms of diplopia following facial trauma; presence of orbital floor fracture confirmed radiologically; presence of muscle entrapment confirmed at the time of surgery; best-corrected visual acuity of 0.6 or more. Exclusion criteria: muscle entrapment visible on computed tomography; candidate for immediate surgical correction; prior history of strabismus surgery. Outcome measures: Abnormal Head Position (AHP), Hirschberg Corneal Reflexes (CR), Cover/Uncover and Alternating Cover Test, Hertel exophthalmometry, Near Point of Convergence (NPC), Kestenbaum Limbus test, Red Filter test, and Hess screen test.
UNASSIGNED: Forty-six subjects (38 males, 8 females, mean age 27 ± 3.3 SD years). Pre-operative assessment: forty-six (100%) reported diplopia on the Red Filter test and showed some degree of abnormality on the Hess Screen test. Forty-two (91%) showed AHP. Forty-one (89%) had exophthalmometry values that differed 2 mm or more between the two eyes and insufficient NPC. Thirty-two (69.6%) showed deficits of 3 mm or more on the Kestenbaum Limbus test. Sixteen (35%) had abnormal Hirschberg corneal reflexes. Eleven (24%) demonstrated constant or intermittent strabismus.
UNASSIGNED: Ocular motility testing can differentiate non-invasively, pre-operatively, and cost-effectively the presence of muscle entrapment even when this is not visible on computed tomography.
