A retrospective study of all plain radiographs taken of optic foramina during the six years 1984-9 inclusive, comprising a total of 318 examinations, was carried out in order to determine the role of this investigation in patients with ophthalmic disorders. All but one of the radiographs were reported as showing no abnormality. However, for this exception, review of the radiographs showed that the optic foramina were asymmetrical but fell within the normal range. This study indicates that plain radiographs of the optic foramina have little or no useful function. Abandoning the use of these views as a routine will result both in a reduction in radiation hazard and in considerable financial saving.
对1984年至199年这六年期间拍摄的所有视神经孔平片进行了一项回顾性研究，总共进行了318次检查，目的是确定这项检查在眼科疾病患者中的作用。除一张平片外，所有平片均报告无异常。然而，对于这一例外情况，复查平片发现视神经孔不对称，但仍在正常范围内。这项研究表明，视神经孔平片几乎没有或根本没有有用的功能。放弃将这些视图作为常规检查将既能减少辐射危害，又能节省大量资金。
