直接接触式眶压计及正常人眶压的研究

Immediate contact orbitonometer and a study on intraorbital pressure of normal people

目的 研究眶压测量器械、正常人眶压及其影响因素。方法 用自行设计制造的直接接触式眶压计对 331例正常人的 6 6 2只眼进行了眶压及眼球突出度测量。结果 用此种眶压计测得正常人眶压为 5 .5 2～ 9.0 0 k Pa。年龄与眶压有高度负相关关系 (r=-0 .97)。眼球突出度与眶压正相关 (r=0 .6 1)。结论 直接接触式眶压计可同时测量眶压和眼球突出度 ,是一种简单、非损伤性的、客观的眶压测量方法。测量眶压有助于了解眶内容物的量和性质 ,为眼眶病的诊断提供依据。

Objective To study the instruments for estimating intraorbital pressure of normal men and the factors affecting it.Methods The immediate contact orbitonometers designed and made by ourselves were used to measures the intraorbital pressures and the prominences of 662 eyes of 331 normal men.Results Measured with this kind of orbitonometer, the intraorbital pressure of the normal men was 5.52~9.00 kPa. There was a high negative correlation between the age and the intraorbital pressure ( r = - 0 97). The intraorbital pressure was positively correlated with the amount of exophthalmos ( r = 0.61).Conclusion The intraorbital pressure and exophthalmos can be measured at the same time with this kind of orbitonometer. This orbitonometer is a simple, non invasive, objective technique for measuring intraorbital pressure. The intraorbital pressure may reveal the amount and the property of the tissue in the orbit and provide diagnostic signs of the orbital diseases.
