目的研究直接眶压的测量方法、正常值及影响因素。方法使用自行设计组装的直接眶压计对40例40只正常眼眶进行测量,同时测量眼压、眼球突出度与间接眶压。结果我国正常人的直接眶压值为(49±12)mmHg。直接眶压与眼压有正相关关系(r=056),与年龄有负相关关系(r=-040)。结论该直接眶压测量仪操作简便、创伤性小,结果准确稳定、能客观反映眼眶内的真实压力。 Objective To study direct measurement of orbital pressure, normal and influencing factors. Methods 40 patients with 40 normal orbital eyes were measured by direct orbital pressure gauge designed and assembled by ourselves. Intraocular pressure, protrusion of the eyeball and indirect orbital pressure were measured at the same time. Results In our country, the direct orbital pressure was (49 ± 12) mmHg. Direct orbital pressure and intraocular pressure have a positive correlation (r = 056), and age has a negative correlation (r = -040). Conclusions The direct orbital pressure measuring instrument is simple, less traumatic, the results accurate and stable, can objectively reflect the true pressure within the orbit.
