老年性白内障患者眼压及压迫降压的个体差异

Individual differences of intraocular pressure and its reduction resulting from reducer in senile cataract patients

白内障手术前压迫眼球已作为常规降压措施应用于临床。本研究旨在探讨老年性白内障患者眼压有何个体差异、不同个体对压迫降压的反应如何。我们对连续90例患者,采用自制的不锈钢压迫器持续压迫双眼15分钟,用 Schitz 氏眼压计测量压迫前后眼压。结果表明,老年性白内障患者,女性眼压较男性为高, (t 检验 P<0.01);左眼眼压的平均数高于右眼,随着体重指数的上升,眼压平均数略有上升,(F 检验 P>0.05)。压迫器对眼球持续压迫15分钟,无论男女及体重指数如何,压迫后较压迫前眼压均明显降低,下降幅度达0.59～0.75kPa(t 检验 P<0.01)。

To decrease the intraocular pressure before the cataract operation,ocular oppression has been used in clinic as a routine.In this prospective study,an attempt was made to find out the individual diffe- ernce of intraocular pressure and its reaction to reducer among the senile cataract patients.A series of 90 cases was collected.The stainless steel reducer made by ourselves was put on both eyes lasting for fifteen minutes.The intraocular pressure was measured with Schiotz tonometer before and after the reducer was given.The results showed that in the senile cataract patients,the mean intraocular pressure was higher in females than in males(t test,p<0.01),higher in the left eye than in the right eye but no statistical significance,and it increased a little with the increase of the body weight index[weight(Kg)/height(m)~2](F test,p> 0.05).After the reducer was put on the eyes lasting for fifteen minutes,the intraocular pressure obviously dropped no matter what sex or weight index.The reduction ranged from 0.59 to 0.75 kPa(t test,p <0.01).
